Was diagnosed nine types of fungi isolated from the roots of wheat and the surrounding soil and different frequency rates and these types. A. alternata, A. niger, R. stolanifer, Mucor sp., Trichoderma hazianum, P. notatum, F. oxysporum, F. solani, Alternaria tenuissima. Testing was diagnosed two fungal species tested using a technique monomer chain reaction PCR. These species are fungal Fusarium oxysporum, Alternaria tenuissima. This study tested the effect of pesticides is a fungal pesticide jungles Granstar and insecticide Wide. The transactions chemical which urea and NaCl in the growth of some fungi isolated from the seeds and roots of wheat as it has been test the effect of different treatments and their interaction in the germination of seeds of wheat on the filter paper and compare nets comparison innate Elsa (Carbendazim) and underwent tests the effects of different treatments and their interaction in radial growth and dry weight of the two types of fungi isolated in the germination of their spores and bacterial length of the tube, as well as test the effect of transactions and their interaction in the germination of seeds in the soil sterile and non - sterile. The results showed that the use of urea and sodium chloride concentration of 15 mg / mL in the treatment of seeds of wheat led to increased germination of these seeds and the impact of a negative in some types of pathogenic fungi associated with them as well as the use of pesticides other than fungal pesticide jungles Granstar and insecticide Wide negative effect also in the vitality Activity and fungi.germination The results showed the existence of significant effects on rates of seeds treated with pesticides and salts on the filter paper analogy transactions comparison since given concentration 15 mg / 10 mL of pesticides and 15 mg / ml of salt are high in the germination of the seed treatment, which exceeded ratios germination of seeds of wheat treatment urea fertilizer treatment fungicide Elsa. As rate ratios germination of wheat seed treatment with urea 96.66%, while the rate ratios germination of seeds of wheat pesticide Elsa 93.33%, followed by treatment of pesticide Wide as rate ratios germination 83.33% and 80.00% for wheat seed when the focus 15 mg / ml of sodium chloride salt treatment, and after treatment Karan Star as the rate of germination rates of seeds of wheat 73.33%. The results showed the existence of significant effects in increasing the proportion of seed germination treatment with pesticides and salts in the soil sterile and non - sterile as it gave the Focus 15 mg / 10 mL of pesticides and 15 mg / ml of salts highest rates of germination of these seeds came these results are compatible with the results of seed germination in the filter paper. The results show that as well as the individual transactions were more influential than the transactions overlap in radial growth and dry weight of fungi testers and their spores germination rates and lengths of germ tubes, as growth rates of radiographic Fungi F. oxysporum and A. tenuissima in the treatment of a mixture Wide and Granstar 11.44, 8.55 mm, respectively, while the rates of diameters of the colonies for the treatment of urea pesticide Wide 33.66 and 26.66 mm, while the pesticide mixture Wide treatment with sodium chloride amounted to 37.00 and 15.00 mm, in while rates were diameters of colonies for the treatment of a mixture Granstar with sodium chloride, 52.66 and 25.00 mm, and the growth rates were radiography for the treatment of pesticide Granstar with urea 25.00 and 11.66 mm, and the growth rates for the treatment of sodium chloride with urea 31.24 and 37.33 mm, compared with the fungicide Elsa, which amounted to the radial growth rates of 8.55 - 11.44 mm Fungi testers respectively.

المستخلص: تم اختبار قابلية عشرة عزلات للعفن Aspergillus fumigatus على انتاج الغليوتوكسين بوساطة تخمرات الحالة الصلبة وباستخدام الرز كوسط زرعي (ركيزة). اشارت نتائج الغربلة ان العزلة AF - 5 كانت هي الافضل واعطت اعلى انتاجية.كانت الظروف المثلى لانتاج السم على وسط الر | The ability of Ten Aspergillus fumigatus isolates for gliotoxin production were screened by solid state fermentation (SSF) using rice medium as substrate. The results indicated that, the AF - 5 isolate was the highest gliotoxin producer.The optimum conditions for gliotoxin production by AF - 5 isolate on rice medium were : - inoculum size 6×106 spores, moisturizing ratio (5 : 1) (w : v) with distilled water and incubation at 37 ?C for 10 days. Gliotoxin was purified from crude extract of AF - 5 isolate after production under the optimum conditions using solid state fermentation SSF. Purification of gliotoxin was achieved by two steps including : filtration and solid phase extraction. These processes were accessed to remove debris from crude extract and gives pure gliotoxin. The gliotoxin concentration was (122.6 ppm), which was detected by Thin layer Chromatography and High Performance Liquid Chromatography.The result of cytotoxicity effect of both purified extract and standard gliotoxin on human lymphocytes with exposure time of 24 hours at four different concentrations 25, 50, 100 and 200 ppb showed growth inhibition percentage 21, 39.10, 61.99, 87.45% and 17.89, 34.92, 58.34, and 85.22% respectively. The cytotoxicity effects have been done using conversion of the MTT to MTT formazan. After DNA was extracted from lymphocyte treated with toxin and analyzed by electrophoresis on a 1% agarose gel, gliotoxin appeared to have ability to damage the DNA. Results showed that both growth inhibition and DNA damage were increased gradually with the increasing of gliotoxin concentration.

المستخلص: استهدفت الدراسة الحالية عزل وتشخيص الفطريات المستنبتة في اوراق نبات الاس Myrtus communis واختبار فعاليتها المضادة للاحياء المجهرية وفعاليتها الانزيمية. - اظهرت نتائج عزل الفطريات المستنبتة في 500 قطعة اوراق للحصول على عدد كلي للعزلات مساويا الى 99 عزلة ف | The present study was aimed to isolate and identify endophytic fungi from leaves of myrtle Myrtus communisand study their antimicrobial and enzymatic activities. - Results of fungal isolation from 500 leaves fragments revealed isolation of 99 endophytic fungi represented a total colonization frequency (CF) of 20.4%. These fungi were related to 23 species or isolates, where Aspergillus spp. prevailed over all others (11 species) with CF of 14% for all Aspergilli, Aspergillusniger and Aspergillusflavus showed the highest CF 7.2% and 3% respectively, other Aspergilli represented Aspergillusparvulus (CF 1.6%), Aspergilluscandidus (0.4%), Aspergillusraperi, Aspergillusclavatus, Aspergillusglaucus, Aspergillusornatus, Aspergillussclerotioniger, Aspergillusterreus and Aspergilluswentii were all showed CF of 0.2%.Other isolates fungi from leaves fragments were four morphologically different isolates of Penicillium with 0.4% CF for each. Additionaly, isolates of Cladosporium sp. (2%) and Cladosporiumcladosporoides (0.4%), as well as Cunninghamella sp., Drechsleraaustraliensis, Alternariaraphani, which showed 0.2% CF for each, Paecilomyces variotii (0.6|%), and different isolates of sterile fungi (White and Hyaline colonies) were also obtained. - Study the antagonistic activity of isolated endophytes using dual culture method against five plant pathogenic fungi(Fusarium oxysporum, Fusarium graminearum, Fusarium sp., Macrophomina phaseolinaandRhizoctonia solani)taking into account the percentage of inhibition of pathogenic fungi, results revealed variation of antagonistic activities between endophytes and pathogens. Different cases of antagonism were also appeared ranged from mycoparasitism of the endophytes on pathogens or vice versa, to competition between the two fungi and to the appearance of inhibition zone between them, this result may indicates the affinity of using some isolated endophytes in biological control applications against or controling fungal plant diseases. - Effect of ethylacetate extracts of culture broth of active endophytes shown in the last experiment against two bactria E.coli, S.aureus and the yeast Candida albicans using disc diffusion method, where filter paper discs were imprignated with different concentrations of fungal broth extracts. Results showed variation of inhibitory activity against bacteria with different endophytes, bacteria and conc. of the extract. Regarding the effect onC.albicans and filamentous fungi, most fungal broth extracts showed no inhibitory activity against yeast and no extract as well showed inhibitory activity on filamentous fungi. These results give indication thatbroth extracts contain antibacterial compounds. - Addition of 20% crude fungal broth of some endophytes to the culture medium showed significant inhibitory activity against filamentous fungi which did not respond to broth extracts, percentage of inhibition ranged between 0 - 77.08% and maximum inhibitory activity was shown by Penicillium sp. Isolate. These results give indication that some of crude filtrates contain antifungal compounds. - Analysis of broth extracts of some endophytes using TLC technique showed the content of extract of number of UV illuminated spots isolated on TLC pates having different Rf values, Bioautography showed inhibitory activity of some of these isolated spots against E.coli, S.aureus and the Filamentous fungus F.oxysporum. - Testing the extracellular enzymes activities of isolated endophyles on solid media, enzymes included amylase, lipase, pectinase, laccase, cellulase and protease showed variation in secretion of these enzymes, as well as, no endophytes showed the affinity of secreting all tested enzymes. Results also showed the high affinity of some endpohytes to secrete enzymes that could be use in multiple important applications after separation andcharacterizationof these enzymes.
