Abstract: The main goal of the current study is the benefit of solar energy as the origin of any renewable energy for producing a hot water through multiple solar collectors each one with overall capacity about 26 liter so that, these collectors arranged in sequential order within the construction of the house without affecting the artistic aspects of the house. These collectors will capable of providing the house the needs of hot water for domestics use especially during the winter season. It will reduce the amount of energy such as electricity and or kerosene or any other source of energy that usually used in Basrah.The present study is included the design and manufacture of seven models of solar collectors. The tools that have used into manufactured of these collectors are some cheap materials that are available in Basrah markets. These models are differ from each other by some aspects with additions properties. The thermal performance and efficiency have a test and then choose the best one in order to use it in four different modern designs of solar heaters.the thermal performance of the manufactured heaters models are tested by calculate the amount of hot water supply under difference weathers conditions in the city of Basrah, which sorts as a large abundance of solar radiation. It also test two types of arrangement of difference parts of heaters. The practical test has been proven the advantage of linking hot water reservoir tank with cold water and then linking the whole system with the hot water tank. This arrangement will allow of gradual warming of the water, which allows the consumer get the hot water directly from the system and not from the reservoir. This study include what is called a feedback arrangement system in order to increase the benefit from solar radiation. In this case, the hot water will recycle to allow for moreexposure to solar radiation repeatedly, that in the case of non - use or the case of little use.All the experiment Steps carried out on the roof of the department of physics building's in the college of education for pure Sciences, Basrah university in the northern city of Basrah, located at latitude 30.50 N and longitude 47.80 E during the winter season 2013 - 2014. Al thought this winter characterized by abundant of rain and clouds the models No.5 shows very good results interm of high temperature of hot water and the amount of it. The temperature was reach (900 C). In addition the model No.4 which depend on the technique of feedback idea shows a good result interm of the amount of hot water produce which reach (146 liter) at a temperature about (500 C) with in only five hours starting at 10 : 00 am until the 2 : 00 pm.In order to develop the optimum dimensional measurements of the solar collectors a mathematical model was developed to predict the output temperature of hot water from the solar collectors or from the radiator in general for different dimensions. This model is working successfully and achieved data that in comparable with our experimental ones. The experimental results have been analyzed theoretically to compare the performance of all solar collectors of the heaters, in different weather conditions and in a same time.

Different weight ratio of Aqueous aluminum chloride (AlCl3.6H2O) are added to the Sol - Gel ZnOwith percentage (0.345%, 0.824% , 1.703% and 2.146%). These solutions are deposited by using spin coating on glass substrate .In order to investigate the sensitivity and the response of these samples for the detection about different vapors and gases (ethanol , methanol , acetone and nitrogen ) , pure and (AlCl3.6H2O) doped ZnO films are prepared by using the same technique but by adding Aluminum electrodes on these films with dimensions (2.5x0.5)cm2 .This preparing is followed by thermal treatment for these films by using oven with temperature reaches to 450 oC.The structure properties of these films are studied by using X - ray diffraction (XRD) and the results show that these films are polycrystalline and the calculated lattice constant are close to the standard values . The samples are analyses by Field Emission Scanning Electron Microscopic (FESEM) and the results show that the grain arrangement are regular and these structures are packed and the grain shape is as spherical . But for the AZO films , we notice that the increasing of the doping percentage reduces the gra in size .We also study the optical properties of these films such as Absorption (A) , Transmission (T) , Reflection (R) , Absorption coefficient (α) , extinction coefficient (k) , the energy gap(Eg) , refractive index (n) , with its complex and real dielectric constant( ) , dissipation factor (tanδ) , Optical Dispersion Parameters (Eo , Ed) and optical conductivity ( ) .

This work elucidates and analyzes the studying of the effect of adding (AlCl3 . 6H2O) o Zinc Oxide (ZnO) and the results are with standards agree with the results of many other researchers . The optical constant are tabulated and compared with , the results of other . And in order to determine the electronic transitions type , Absorption coefficient is calculated and it shows that ZnO and AZO films have transition of direct type because the values of α > 104 . The energy gap of the ZnO films with different thickness (58,69 and 77) nm is calculated , since it is found that the increasing of the film thickness gives slight increasing in the energy gap .

Abstract: The study was conducted to investigate several taxonomic aspects which comprised the micro - morphological studies of epidermal layer of leaves, pollen grains, fruits and seeds.In addition to that, the anatomical and molecular studies for 12 species of Euphorbiaceae family which belonged to five genera AndrachneL. , Chrozophora L., Euphorbia L, Mercurialis L. and RicinusL., were performed. One representative species for each genuswas selected; in exception 8 species were chosen for the genus Euphorbia..The current results confirmed that the anatomical characters showed valuable taxonomic traits which can evidently be used to distinguish between species. The most prominent trait was mesophylla tissue in leaves which were observed in three categories;1 - Bifacial leaves : - which found in C.tinctoria, Euphorbia sp ., E. milii, E.annua and R.comminus 2 - Uni - facial (heterogenus) leaves : - this category of the mesophyll was detected in two species only A.telephioides and E.prostrata3 - Uni - facial (homogenus) leaves : - this category were noticed in five species; E.denticulata ,E.helioscopia ,E,macrocarpa , E.microsphaeia and E.peplus The second important comparative anatomical character was the Mid rib, which are in four types with several shapes from which discrimination between the species can be made : - 1. Convex - concave mid rib : - that was showed in E.helioscopia, E.macrocarpa, E.milii and M.annua.2. Convex - convex : - This type was found in three species C.tinctoria , Euphorbia sp.and R. comminus3. Flat - Convex : - This type of mid rib was observed in A.telephioides E.microsphaera, E.peplus and E.prostrata4. Flat - Flat : - This type was observed in only one species E.denticulata In stem, the most prominent parts of taxonomic evidence were pith and vascular bundles.In according to the pith, species can be divided into hollow stem (without pith) and solid stem (containing medulla good configuration). Hollow stem was clear in the stems of A.telephioides , E.microsphaera , E.prostrata and M.annua. While, the solid stem wasseen in the remaining species. Vascular bundles were existed in two types; that's connected vascular bundles that's characterized the hollow stems, and separate vascular bundles. In most of the species with the exception of M. annua, stem with scatteredvascular bundles were in cortex As well as, petiole which have features that a clear taxonomy values .either by outline of petiole or its vascular arc.Micro - morphological studies of epidermal layer of leaves showed very important taxonomical value. This layer of leaves reveals variation in shape of ordinary epidermal cell and nature of anticline cell wall, stomata complexes and Epicuticlular wax crystals.Micro - morphological of pollen was taxonomic evidence as well. It can be considered to divide the species of Euphorbiaceae family into two groups based on the number of germination apertures 1 - Hexocorporate : - this type was confined to C.tinctoria2 - Tricolporate all species studied remainingThe sculpture of pollen wall provided beneficial information invested in the species identification.Both seeds and fruits showed a distinctive role in species identification. Micromorophological study of seeds for species which belong to six genera Andrachne , Chrozophora, Euphorbia, Mercurialis , Phyllanthus and Ricinus were achieved by using Scanning Electron Microscope(SEM). The study concentrated on micro - morphological aspect of Caruncle, seed surface ornamentation and the shape of epidermial cell wall. The result revealed that most studied species were with carunclated seeds ,but some specieswere with ecarunclated seeds as in A.telephioides L. ,C. tinctoria( L) Raf , E.prostrata Atin and P. maderaspatensis L Seed surface ornamentation characteristics showed a significant taxonomical value.Furthermore, current result showed that there are a highly variation in shape, size and color of the seeds walls. With respect to the fruits characteristics, which showed variations in number of mercarpi, shape, size, color and surface ornamentation that can be adopted in the separation of the species studied Molecular study provided significant support for phenotypic and anatomical classification and support genetic convergence between the species in Euphorbiacea family. The genus Euphorbia species showed a significant genetically convergence and participated in predecessors monophyletic. However, the genera in Euphorbiacea family under study probably originated and evolved from different ancestors’ polyphyletic.

Abstract: A total of 401 represented by 128 birds of Himantopus himantopus which belong to the family Recurvirostridae , 93 birds of Chettusia leucura which belong to the family charadriidae and 180 birds of Sturnus vulgaris which belong to the family sturnidae at the period from April 2014 to march 2015 in Al - Sanaf marsh , Suq - Al - Shuyukh city southern of the Thi - Qar province,for searching the nematodes which belong to the family Tetrameridae. Four species of nematodes, which belong to the family Tetrameridae, were isolated in the current study. They were T.nouveli, T.dubia, T.spinosa and Microtetrameres inermis. The H. himantopus was infected with the nematode T.nouveli and the prevalence of infection was 25.8% , bird.Furthermore, the Chettusia leucura was infected, the mean intensity was 3.3 worm in each infected birds. The nematode T.dubia was isolated from H. himantopus with the isolated from the Ch. Leucura mean intensity was 1.7.The nematode T.spinosa was isolated from H. himantopus the the mean intensity of infection was 2.3 and it was isolated from the Ch. leucura , the prevalence of infection 4.3% and the mean intensity was 1.8 worm in each infected worm.The record of these three nematode is considering the first record in Iraq.Microtetrameres inermis was isolated from the Sturnus vulgaris, the each infected birds.Himantopus himantopus from April 2014 to March of 2015.This bird was infected with three species from family Tetrameridae, The seasonal variation study of infection prevalence of Tetrameres spp.in, H. himantopus that there was II Summarycomplete seasonal cycle for nematodes T.nouveli, T.dubia , and T.spinosa .The nematode T.nouveli had hightest infection prevalence in summer the decrease in autumn, winter and spring while the infection prevalence of nematode T.dubia was hight in summer and autumn then decrease in winter and spring. The infection prevalence of nematode T.spinosa was generally low with little increase in autumn .The results of the current of the Ch. leucura indicated that this bird was infected with three species which nematodes T.nouveli, T.dubia and T.spinosa and they had seasonal appearance . There was not any significant effect of host sex on prevalence of infection, and it showed decreased in prevalence of infection when the bird's weight was increased.The study of lifecycle of nematodes : T.nouveli ,T.dubia and M. inermis revealed obtainment the larval stages after success the infection experimental of the grasshopper Schistocerca gregaria for the first time the three isolated nematodes from family Tetrameridae in this study which it was T.nouveli , T. dubia and M.inermis and was included the lifecycle of the three species . The differences were including the period of time to produce and developing the larval stages in addition to the differences in their shapes, it was revealed that were clear differences in the structure and their shape of the tip the posterior end of the third larval stage. The end of the third larval stage of the nematode T. nouveli had three caudal papilla and the posterior end of nematode T.dubia had five caudal papilla while the end of the third larval stage of M.inermis did not have any caudal papilla , so we can distinguish these nematode larval stage depended on the prevalence this character in their third larval stage.The experimental infection of the Columba livia domestica with nematode M.inermis was successful.While the experimental infection to the Columba livia domestica with nematode T.nouveli ,T.dubia .was failed The experimental infection of the Gallus domestica with nematodes of Tetrameridae T.nouveli, T.dubia and M.inermis was failed too.

Abstract: The present study was concerned with some biological aspects of the invasive snail Pomacea canaliculata (Lamarck, 1822) and for this purpose, monthly samples from Shatt Al - Arab banks in the area of Al - Salhia were collected during the period from October 2014 to September 2015. The study included the monthly variations in the density of snail , its egg masses and the population sizes. In the laboratory, the study included many aspects, these are the relationships between female weight with some measurements of its egg masses, embryonic development duration, hatching percentages under different temperatures, food consumption, salt acclimatization, growth under combined effect of salinity and temperature, effect of food type on growth of newly hatched snails and examine samples of snail to detect the infection with parasites if present. The density of the snail was ranged from four to 13 ind. /m2 recorded during January - February 2015 and October 2014 respectively, while the mean density of egg masses was from two to nine egg mass / m2 recorded during April 2015 and October 2014. The statistical analysis showed that the temperature had positive correlated with density of each of snails and its egg masses. On the otherhand, there are positive correlation between the density of each snail and its egg masses. The snails, which had been collected during the study period, were 19 - 68 mm in length, these measurements were classifying into five size classes. The size class 35 - 45 mm was dominanted for nine months, compared with the size class 55 - 65 mm that had less occurrence.The diameter of eggs varied from 2.5 - 4 mm. The 25°C is the most suitable temperature to get a high percentage of hatching and a short period of embryonic development. There was no significant correlation between the weight of the female and the number of its egg masses.The feeding experiment showed that the amount of food consumed lettuce mild during the study period 30 days by one individual ranged from 3 - 29g. The results of the acclimatization was referred to the ability of all size classes' snails to tolerate the low salinity 2.5 psu with 100% survival percentage, while the snails of size classes at least 10 mm and 10 - 25mm were able to tolerate the salinity of 11psu with 10% and 50% respectivly survival.There are variable effects of the combination of temperature and salinity on growth of newly hatched snails for 9 weeks experiment, these effects were reflected on the weight, length and width, and the highest of these measurements were recorded for snails of 2.5 psu - 27°C combination, while the lowest one was recorded in 7.5 psu - 10°C. The lowest survival percentage was 5% recorded for the individuals of 7.5 psu - 27 and 32°C, compared with 90% of distil water - 17°C. On the other hand, the optimum growth was in 2.5 psu all temperatures, while the optimum growth was in all salinities, and temperature of 27°C.The experimental study of five types of food fresh celery, fresh lettuce, fish food, mixed food and animal protein)on growth of newly hatched snails for 9 weeks. Showed that the mean weight, length and width of snails were depending on the food type. The mixed food gave significant increase in growth 382.1 mg weight, 10.10mm length and7.58mm width compared with the other types of food.The highest survival percentage 95% was recorded for the snails fed on celery, lettuce and fish food. The present study on the snail P. canaliculata does not record any infection by the larvae of parasites

Abstract: The purpose of present study was to detection of Rotavirus A and Escherichia Coli from diarrhea cases in children, and characterization of E.coli phag, in addition to study some of factors that influence on Diarrhea.Stool samples were collected between 15/11/2014 and 1/4/2015 from children 0 to 59 months of age who were hospitalized in Basra hospital for women and children, Basra/Iraq. A total of 300 children with acute gastroenteritis were enrolled, including 199 males and 101 females.In this study among children with Diarrhea was 93/300 (31%) Rotavirus positive cases by Immunochromatographic (IC) test as monoinfection (1.66%), coinfection (26.34%), and mixing infections (3%). Out of 50 IC positives fecal samples were tested using electronic microscope, 50(100%) were found positive. A total of 80 stools were examined for Rotavirus using polyacrylamide gel electrophoresis. The overall agreement was 68/80(85%).Furthermore, regardless of the types of infection, monoinfection or coinfection or mixing, Bacteria was isolated, including; 277/300 (92.33%) children had infections with Escherichia coli, 39/300 (13%) cases with Salmonella spp., While, Shigella spp. was reported in 12/300 (4.01%) samples. The identification of bacterial pathogens was later confirmed by Api 20 Enterobacteraceae system. Also parasitic causes were found in 6/300 (2%) samples.Overall, this study recorded 182 /300 (60.66%) of monoinfection cases including; 5 /300 (1.66%) with Rotavirus, 163 /300 (54.33%) with Escherichia coli, 6 /300 (2%) with Salmonella spp., 2 /300 (0.67%) with Shigella spp., 3 /300 (1%) with Entamoeba histolytica, 3 /300 (1%) with Giardia lamblia. Coinfection with another microorganism was observed in 109/300 (36.34%) cases, coinfection with Rotavirus and Escherichia coli were the most common and occurred in 75/300 (25%) cases.Antibiotic susceptibility testing was performed on Muller Hinton agar against five different antibiotics to 30 isolates of E. coli. The antibiotic resistance/susceptibility profile of E. coli isolates revealed that most of the isolates were resistant to three tested antibiotics (Trimethoprim, Ampicillin and Doxycyclin). The phage ɸEC - MH1 was isolation successfully from sewage. The phage titer was determined by serial dilution (10 - 1 to 10 - 9) of the sample by counting the number of plaque forming units (p.f.u.) for each dilution.Results revealed that dilution factor 10 - 2 was the best countable number of plaques. The statistical analysis was significantly decrease P≤ 0.05 in phage titer at the temperature 50C° and 65C° during different times comparing with phage titer at the temperature 37C°. Effects of chloroform on phage titer during different times were completely inactivated comparing with saline environments. Furthermore, regarding some clinical information; the present study showed that 66.33% of the males were more susceptible to the infection with highly significant (P<0.001) than females (33.67%). Mean age (mean ± standard deviation) of all positive cases was 11.02±12.3 months, and the age periods between (0 - 5) and (6 - 11) were significantly prone to the infection.Also, all cases were complained with diarrhea (100%), fever (82.34%), Vomiting (43%) then dehydration (2.67%). In addition, all positive cases become increased in December (32%) and city center (81%). This study showed positive cases increase (69%) of children with artificial feeding

Abstract: It was collected 318 mole cricket insects randomly from four regions in Missan including AL Kahala district by 191 insects, AL Mishraah by 62 insects, Kalat Salih by 61 insects and New Hay AL Hussein ( Centre of the city) by four insects. The period was from September 2013 to August 2014. It was diagnosed one species of mole crickets which is G. gryllotalpa decended from Gryllotalpidae families because of its essential charact ristics such as the general form of the insect, shape of the wings and legs, and its site and colour. In addition, there is a large lobe in the front legs of the insect and there one two species of veins in the front wings of the male used to attract females for mating. The life cycle of the insect was studied in the laboratory. Itstransformation is characterized by being imperfect progress, on egg, then a nymph and then an adult. The female lays about 100 eggs oval - shaped and grey in a room in the soil. The period of preegg - laying is approximately 100 days and the percentage of hatchling is 74% . The females remain alive after one day egg - laying is completed while the males remain 13 days after egg - laying. The eggs hatch into nymphs which pass stages of life development andit takes 115 day - Newly hatched nymphs are transparent and grey, its length is 10 mm with antennas and small cerci which are without wings. Wings begin to appear in the sixth stage of life. Then nymphs develop into brown adults with a large filled body. Its length is about 40 mm and all parts of the insect continues to grow in proportion to the size of the insect.After examining these insect, it showed that they are infected with seven species of nematode parasites. They are Binema ornate, Binema korsakowi, Binema anulinervus, Cameronia triovata, Cameronia multiovata, Mirzaiella asiatica, Grylophilla skrjabini. The Prevalence of those nematodes are 18%, 13%, 1%, 2%, 1.0%, 22% and 25.6% respectively. while the mean intensity of infection was 1.5, 1.6, 3.5, 4.5, 8, 1.5,2.15 respectively.Four of these species of nematodes were considered as new record in Iraq, These are : Binema anulinervus : Most important feature in the shape of the high - tail and long that look like a flagella.Mirzaiella asiatica : Featuring male this form of the parasite by the short and broad and meandering tail. The female is characterized by a length of the muscle of the esophagus and the existence of the tapes curled at his side. Cameronia triovata : The most important feature of this parasite egg shaped oval that is flat from one side. C. multiovata : What also distinguishes this form of the parasite is a large and long oval egg.Nematodes were a taxonomically quoited and illustrated.The species B. ornate and G. skrjabini appear repeatedly over 10 months followed by the parasite B. korsakowi for eight months then followed by M. asiatica for seven months, as for the parasites B. anulinervus, C. triovata, C. multiovata for two months

Abstract: The present study intended to shed the light on some biological aspects of the invasive oriental river Shrimp Macrobrachium nipponense compared with that of Jinga shrimp Metapenaeus affinis . For this purpose, Monthly samples were collected and chosen from four Aquatic sites was chosen in the Basrah province (one at each of Al - Mashab and Al - Sallal Marshes and two at Al - Garmah River) during the period from July 2015 to June 2016. collection was done by Fishnet pulled by a boat .The Shrimp numbers were calculated during the time unit (ind./hour) .The Water’s temperature and salinity were studied, it ranged from 15 - 33 ͦ c and 2 - 9.1psu respectively. From a total of 3326, individuals were collected during the study period, only 7% were belong to the first shrimp (M. nipponense ) Compared with 93% to the second shrimp( M. affinis ).The number of each species studied shrimps, varied the monthly. The high number of M. nipponense was 38(ind./hour) recorded during July 2015 and June 2016, while the lowest was 2 (ind./hour) recorded during October and November 2015 . For M. affinis The number of individuals ranged between 980(ind./hour) during August 2015 and 29 (ind./hour) during November 2015 .The comparative monthly percentages were high during seven and six months in the marshes sites recorded for first and second shrimp respectively. The monthly variation in percentages of the two species of shrimps was studied, It ranged (for M. affinis) from 98.8% during August 2015 to 56.8% during July 2015 , while for M. nipponense , It ranged from 43.2% during July 2015 to 1.2% during August 2015 .The results of Frequency showed that the highest percent (100%) was recorded in four months for M. nipponense , these are July, October 2015 February and May 2016. While M. affinis was recorded in most months.Summary bThe population sizes for the two species were studied. For the first species( M. nipponense ), the size class 50 - 60mm dominant during all months of the study period, While for the second species (M. affinis), the size classes 40 - 50, 50 - 60, 60 - 70, and 70 - 80 were recorded during all the months for the first shrimp, the highest percent was 47.3% recorded for the size class 70 - 80 mm , While there is no individuals recorded for the size class 10 - 20 mm during all the months except July 2015 for the second shrimps ,the percentage ranged between 41.4% and less than 1% recorded during May 2016 to March 2016 respectively. On the other hand , the total Frequency for M. nipponense ranged from 83.3% to 0% for the size classes 70 - 80 mm and 10 - 20 mm respectively, While for M. affinis was from 100% recorded for the classes 40 - 50, 50 - 60, 60 - 70 and 70 - 80mm to 8.3% for the class .The Length - Length and Length - weight relationships for the two species were studied The results showed positive correlation between the total length and each of cephalothorax length and abdomen length (r= 0.932 and r= 0.945 respectively, P≤0.01 ) for M. nipponense , Also M. affinis , the correlation was positive for the total length and each of cephalothorax length(r= 0.938) and abdomen length (r= 0.971) (P≤0.01 ) . The correlation was positive between the total length and wet weight for each M. nipponense (r= 0.918 P≤0.01) and M. affinis (r= 0.913 P≤0.01).The Statistical analysis for the weight - weight relationships showed positive correlation between dry and wet weight for M. nipponense (r= 0.966, P≤0.01) and M. affinis (r= 0.918 P≤0.01).The correlation between the lengths of the body and the 2nd chela for male & female of M. nipponense (r= 0.909 and r= 0.823 respectively), these values of correlation refer to the continuous growth of the 2nd chela in male even after the adult stage .Summary cThe concentrations of ten heavy and light metals in shells & muscles of the two shrimps were studied. The results showed a significant differences in eight of them (Cadmium, Potassium, Calcium, Iron, Magnesium, Nickel, Zinc and Sodium) . While there is no significant differences recorded for Lead and Cobalt .The study of some biological aspect which concerned with distribution of eggs on pleopods of females of M. nipponense , showed that the highest mean of eggs was 547.3 (38%) carried on the 2nd pleopod while there are fewer means carried on 1st and 3rd pleopods , and no carry eggs (0%)were carried on the 5th pleopod. The Statistical analysis showed that there was significant differences between the eggs carried on 4th and 5th pleopods and each of the rest ones . lengths of pleopod was positively correlated with the number of eggs (r= 0.661, P≤0.01) The weight of ovigerous female was positively correlated with weight of eggs (r= 0.835, P≤0.01) .The combined effects of salinity and temperature on survival of newly hatched larvae (zoea1 and zoea2) of M. nipponense for 24 & 48 hours’ were tested.The highest survival percentage (100%) for zoea1 was recorded in 12 psu salinity in each of 18, 22 and 26 ͦ c ,While the lowest survival (0%) was recorded in distal water in each 30 and 34 ͦ c . the highest survival percentage was recorded in 12 psu salinity in each 18, 22, 26 and 30 ͦ c. While the lowest one recorded in distal water and 34 ͦ c. The Statistical analysis showed that the percentage survival correlates negatively with temperature and positively with salinity each alone. the combined effect of salinity and temperature on survival was positive with percentage ranged between 38 - 56 % .

Abstract: The present study was conducted during November and December 2013.It included studying six inner rivers branching from Shatt al - Arab river in Basrah governorate.These rivers are Abu Al - khasseb, Al - Ribat, Al - Khandaq, Al - Ashar, Al - Khura and Al - Sarraji .The study included isolation and identification of three species of genus Bacillus which are B. licheniformis,B. megaterium and B. badius ,and two species of genus Micrococcus which are M. halobius and M. kristinae .Physical and chemical characteristics of the water samples were measured, which including pH,temperature,electric conductivity and Dissolved oxygen. The results showed that there were not correlation between physical and chemical characteristics and the concentrations of the heavy metals except for water temperature which had a negative significant correlation with the concentrations of nickel and lead.The concentrations of heavy metal dissolved in water (copper, nickel , lead and cadmium ) were measured. The concentrations of Cu+2 and Pb+2 were higher than that of Ni+2 and Cd+2 in the water .However,in general the concentrations of Cu+2, Ni+2, Pb+2 and Cd+2 were high in comparison with the local and international standards.All species of bacteria showed high resistance to the heavy metals ions starting from concentration of 1 mg/l. B. licheniformis was recorded high resistance to Pb+2, Cu+2 and Ni+2 which reached 2600 mg/l, 500mg/l and 300mg/l respectively. M. halobius was also recorded a high resistance to Pb+2 and Cd+2 with 2600mg/l and 400mg/l respectively. The highest resistance was recorded by M. kristinae to nickel with 300 mg/l . The mid resistance was by B.badius to all studied heavy metals and the lowest was by B. megaterium to all heavy metals studied in comparison with the other species of bacteria.The identified bacteria were used in the process of bioremediation of the heavy metals (Cu+2, Ni+2, Pb+2, Cd+2) with different concentrations (25, 50 and100 ) mg / l. B. licheniformis showed high ability to remove Ni+2, Cu+2 and Cd+2 than other species of bacteria, which reached (28.30%, 44.34% and 24.27%) mg/l. . respectively. B. badius showed a high capability for removing Cu+2 with 45.78% mg / l .Where as B. megaterium showed a high capability for removing Pb+2 with 23.43% mg / l.. M. halobius had the highest capability for removing Cd+2 with 25.42% mg / l. and M. kristinae had a mid capability to remove the heavy metals under studied.The study included observing the effect of the incubation period on removing the heavy metals ions.The results found that the best period was 72 hours in comparison with 24 and 48 hours.Also, the study included the effect of initial concentration in the process bioremediation.The results showed that the concentration of 25mg/l was the best for removing the heavy metals ions among the other concentrations, 50 and 100 mg/l.

Abstract: The current study includes an isolation, Identification and purification of three species of algae, two of them belonging to cyanobacteria they are Oscillatoria brevis and Nostoc carneum . The third one was Enteromorpha intestinalis which belong to green algae which was from different location in Basrah .There are two extract were prepared from the algal species Alcohol , and alkaloid extracts , Alcoholic extract prepared to know what was compound it had and alkaloid extracts to test bioactivity of algae Cytotoxcity also was carried out on human red blood cells, the results revealed that alkaloid extract from E.intestinalis was nontoxic, whereas bioactive compounds isolated from O.brevis , N.carneum. Showed hemolytic action .The bioactivity of alkaloid extract was examined to elucidate their on ability to inhibit the growth of gram Positive and negative bacteria. .Biological activity of alkaloid extracts of three algae isolated were determined by using the Minimal Inhibitory Concentration (MIC) againsttwo bacterial isolates. And also test the effect of filtrate pure algal culture on growth of plant pathogenic fungi ,also apparently that the algal alkaloid extract and isolated compounds exhibits antioxidant.The antitumor activity of the algal alkaloid extract from E.intestinalis against Rhabdo myosarcoma cell line was examined. The results showed that crude alkaloid extract possessed an antitumor bioactivity at low concentration 0.78mg / ml .In this study also was carried out to investigate the possibility of preventing the hypercholesterolemia by using alkaloid extract of E.intestinalis .it also aimed to study the effect of use this extract in reducing the Plasma Total Cholesterol (TC) , Triglyceride (TG), Low - Density Lipoprotein (LDL) , Very Low - Density Lipoprotein (VLDL) and no effect on High - Density Lipoprotein (HDL).The identification of the compound was made depending on the active groups test and spectroscopic analyses including : Infrared (IR) and Gas Chromatography / Mass spectrum (GC - MS). The results of such analyses showed that alkaloid extract from E.intestinalisa has three compound these are Hexadecanamide , Methenamine and Benzenedicarboxylic acid, diisooctyl est and alkaloid extract from N.carneum showed that has three compound 1,2 - Benzenedicarboxylic acid diisooctyles,ا9 - Octadecenamide, (Z) - )ااااا and Didecyl phthalate .Hexadecanamide purification from alkaloid extract of E.intestinalis depended on physical and chemical properties The identification of the compound was made depending on the active groups test and spectroscopic analyses including : Infrared (IR); Gas Chromatography / Mass spectrum (GC - MS) and this component showed bioactivity on gram. Positive and negative bacteria and it has also antioxidant activity

Abstract: The current study was designed to investigate active compounds from different Penicillium isolates ,that isolated from different sources , using different media . Eleven isolates related to five species : P. chrysogenum, P.paxilli , P. citrinum, P. cosmopolitanum, P. digitatum were isolated. After primary screening was performed , the best isolates that have high antibacterial activity against gram positive and gram negative bacterial was selected. The selected isolates were cultured on fermentation media according to the suitable media for each isolate, and the active compounds were extracted using ethyl acetate as a solvent. P. cosmopolitanum and P. chrysogenum were cultured on penicillin production medium (PPM) , P. paxilli was cultured on Aspergillus complete medium (ACM) and P. digitatum and P. citrinum were cultured on solid state fermentation media consist of wheat bran . The efficiency of fungal crude extracts from each isolate against the reference strains S. aureus NCTC 6571 and E. coli ATCC 25922 and against Candida albicans (pathogenic and reference strain)was examined, and the Minimum inhibitory concentration (MIC) was determinated for each extracts.The inhibition zone of fungal extracts against E. coli and S. aureus ranged between (20 - 50) mm , and they had high activity against C. albicans ( reference and pathogenic isolate) ranged between 25 - 45 mm.Induction of secondary metabolite production by the selected fungi was carried out using biological factor (Streptomyces sp.) , chemical agent (colchicine) and physical agent by UV radiation. Apparently that the biological induction by Streptomyces isolate was the best compared with the other treatments.The results revealed that the two fungal extracts ALO1 and Apax exhibit a high antioxidant activity at low concentrations and volumes of the extract compared to ascorbic acid as control. ALO1 had radical scavenging activity (RSA%) reach 99.9% at volume 3μl , and Apax had RSA 91.6% at concentration 500μg/ml. Also, the fungal extract ,ALO1, showed a significant activity as anticancer agent against RD - cell line. The IC50 of ALO1 was 8.5μl after 24h and 23.76μl after 72h. The hypercholesterolemia ability of ALO1 in vivo and in vitro was assayed . In vivo experiment designed using female albino mice and divided into three groups each one contain 8 mice : group 1 treated with 10μl , group 2 treated with 20μl of ALO1 , and group 3 treated with normal saline as control group. The results showed that total cholesterol , triglycerides, LDL and VLDL were significantly reduced when compared with control group while the HDL level was increased in comparing with control group. The chemical analysis of the crude extracts showed that Apen2 contained 259 μg/g of penicillin G when analyzed with HPLC apparatus . Also the GC mass analysis of ALO1 showed that Docasadionic acid initialize area76.18% and Palmitic acid initialize area 15.09% from the total identified compounds.Whereas the GC mass analysis of Apax showed that Hexandioic acid initialize area40% and Stearolic acid initialize area 35.57% from the total identified compounds.In addition , it was detected the presence of penicillin biosynthetic gene cluster : pcbAB, pcbC and penDE in P. cosmopolitanum and P. chrysogenum.The result showed that gene pcbC and penDE were found in the genomic DNA but the gene pcbAB was not amplified by PCR.
