Abstract: This study was conducted to investigate and test the activity of three essential parts of wheat seed Aleurone, germ and bran which were used as secondary products from grinding grain to feed animals. diversity solvents (distilled water, chloroform, hexane, ethanol, methanol) were applied to extract the bioactive compounds by both traditional and modern extractions.The total phenolic compounds, antioxidant activity, reducing power, metal chelating, and scavenging of hydrogen peroxidase were determined for all three essential parts of wheat. The stability of the extracts was studied toward temperature and pH at the interval time. In addition, the synergistic effect of the extracts was studied by mixing with different concentrations of ascorbic acid and alpha tocopherol. The extracted compounds were identified using gas chromatography mass spectroscopy (GC - Mass).The ethanol extraction of wheat germ had the highest antioxidant activity, so it was chosen to prevent oxidation in the corn oil. Moreover, the ethanol extractions for germ, bran and Aleurone were added to wheat flour (80 % extraction) in order to study their effects as improvers in the rheological properties of wheat flour dough. The results were as follows : 1 - The microwave - assisted extraction for 40 sec was able to extract the highest level of phenolic compounds from wheat germ compared toconventional extraction conditions. The total phenolic compounds were 556.6 μg gallic/ml, 426 μg gallic/ml for ethanol and methanol extractions, respectively.2 - The microwave - assisted extraction was able to give the highest antioxidant activity (53%) at concentration of 100 mg/ml from ethanolic wheat germ extraction compared to synthetic antioxidant BHT ( 92 %). In addition, the wheat germ had the highest reducing power (163.88 %) at concentration of 5 mg/ml , while the percentage of reducing power for both ethanolic extraction of Aleurone and ethanolic extraction of wheat bran were 112.63 % and 79.68 %, respectively. In contrasts, all of above extractions had lowest reducing power compared to BHT and alpha tocopherol 249.8 % and 223.5 % respectively at the same concentration. Moreover, the wheat Grem had the highest percentage for both Ferrous chelating and scavenging of hydrogen peroxidase.3 - Ethanolic extracts of Aleurone, bran and germ have a higher antioxidant activity in natural pH while decreased when treated with acid and alkaline. In addition, the ethanolic wheat germ was able to give the highest antioxidant activity at 100°C for 100 min wich read 62.2% compared to others and gave synergistic effect for bothascorbic acid and alpha tocopherol exhibited 91.90 % of antioxidant activity at concentration 60 mg/ml.4 - Identification of ethanolic and methanolic extract using GC/MS showed presence of bioactive compounds such as ascorbic acid, benzoic acid, phytosterol compounds, Isoeugenol and alkylresorcinols5 - Ethanolic extracts of germ with concentration 0.05, 0.10, 0.15, 0.20, 0.25 mg/g was added to corn oil in order to compared with BHT 0.05% and stored at 45°C for 28 days, the result showed that the ethanolic wheat germ at 0.25 mg/g had the ability to decrease the hydrogen peroxide for the corn oil 6.8 meq/kg at end of stored time compared BHT (0.05 %) 4.3 meq/kg at the same conditions.6 - The ethanolic Aleurone extraction possessed a positive effect on the rheological properties when it was added as improvers to the wheat flour ( 80 % extraction). The dough consistency was 6.7 min, which considered highest reading among all treatments. In addition, the recorded elastic index was 3.2, 2, and 1.8 at interval times 45, 90, 135 min, respectively.

Abstract: A field experiment was conducted at Al - Daire site 40 km north of center Basrah Governorate .The study was conducted to investigate the effects of different nitrogen fertilizer levels on dry matter accumulation, (N, P, K) uptake, distribution in different parts of three cultivars of wheat plants and their yield during two seasons (2011 - 2012 & 2012 - 2013).The experiment was split - plots in R.C.B.D design with three replicates, Nitrogen rates (0, 60,120 and 240Kg ha - 1 occupied the main plots, while (IPA - 99, Abu - Graib and Latifia) Cultivars Occupied the sub - plots. Samples of wheat plants were collected at 10 growth stages : seedling stage, tillering (main shoot and 1 tiller), tillering (main shoot and 4 tillers), stem elongation, booting, 50% of spike emergence, 50% flowering, milk stage, dough stage and maturity. Each plant sample was separated into different plant parts : blades, sheathes, stems, flag leaves, spikes and seeds. These parts were dried at 70°C and dry weight of each part was recorded and sub sampled for chemical analysis of N , P , and K. Growth parameters (No. of day till 50% flowering , No. of day from 50% flowering to Maturity , flag leaf area , plant height, spike length and No of tillers m - 2) , yield components (No. of spike m - 2, No. of grain in spike and weight of 1000 grain ),grain yield, biological yield, harvest Index, grain protein percentage and nitrogen use efficiency were also studied.Results showed that dry matter accumulation in plants of all cultivars did not differ at early growth period, While after the growth stage of 50% flowering plants dry weight of Cv.IPA - 99 was higher than other cultivars, This difference in dry weight continue till maturity stage at which total dry weight were 14473.58, 13373.96 and 12743.59 Kg ha - 1 for IPA - 99, Abu - Graib - 3 and Latifia respectively.Dry matter yield were not affected by N levels during the early growth period ,then after dry weight of plants increased as N rates increased ,total dry weight were10752.61, 12737.49 and 15347.10 Kg ha - 1for 0, 60 , 120 Kg Nha - 1 respectively, with no differences between 120 and 240 Kg Nha - 1 levels.Dry matter of plant parts differed among cultivars, with IPA - 99 having the highest results. Increasing nitrogen rates increased weight of different plant parts, but did not influence the relative proportion of each plant part for all cultivars.IIResults also showed reduces in dry weight of different plant parts(except grains)after reaching a maximum weigh at dough stage for Spikes, and 50% flowering for the other parts. The highest decreased was in blades and lowest in sheathes. The application of N fertilizer decreased translocation of dry matter from plant parts to grains. Data showed that no differences in nutrient uptake were observed for cultivars till ending of tillering stage, but after this stage IPA - 99 cultivar showed highest uptake till the end of the season. Nitrogen uptake was157.68,136.72,124.51 Kgha - 1 ,P uptake 19.70,16.93,15,67 Kg ha - 1, K uptake136.30,121.10,112,60 Kg ha - 1 for IPA - 99,Abu - Graib - 3 and Latifia, respectively.Increasing N rate increased nutrient uptake of different plant parts, but did not influence the relative proportion of each plant part for all cultivars.uptake of N, P, and K for all cultivars and nitrogen rates declined as the season progressed, this decline differed among nutrients and plant parts.Grain contained 59.20, 79.00 and 7.45% of total nutrient N, P and K uptake, whereas vegetative parts contained 40.80, 21.00 and 92.55% of total nutrient uptake, respectively.Cultivar IPA - 99 resulted in highest grain yield among studied cultivars. Increasing N rate from 0 to 120 Kg N ha - 1 only increased grain yield, the rate 240 KgNha - 1 did not affect yield significantly as compared with that of 120 Kg N ha - 1.Results also showed a significant interaction between Cultivars and N rates. The highest grain yield obtained at treatment IPA - 99×240 Kg N ha - 1with no significant differences than IPA - 99×120 KgNha - 1.Results indicated that highest nitrogen use efficiency (66.23%) was found in plant of IPA - 99 cultivar, whereas, the lowest efficiency (47.37%) was found in plant of Abu - Graib - 3 cultivar. At all cultivars increasing N rates to 240 KgNha - 1 decreased nitrogen use efficiency.Therefore it can be concluded that 120 Kg Nha - 1 can be recommended as the best rate for N to all cultivars under similar growing conditions

The results of spcific activity estimation showed that , the best kind of oil seeds are soy bean seeds, they gave the highest specific activity of enzyme before and after germination 3.58 and 11.20 unit/ mg protein respectively comparing with other varieties. Lipase was extraction from soy bean seeds before and after germination using nine extraction solutions the best extractant solution was Tris - HCl 0.10 M containing 0.01M calcium chloride and 0.001mM ethylene di amin tetra acetic acid and 0.001 mM magnesium chloride pH 8. Lipase improvement was monitored through the germination period of soy bean seeds, it reached the highest activity of lipase after five days of germination ,which was 38.00 unit / ml .The chemical composition of soy bean seeds studied before germination period and through different germination period , higher protein percentage was noticed in the germination seeds where it reached its peak at the end of five days of germination 41.60 % compared with protein percentage before germination 35.57 %. For the percentage of fat, charbohydrates and ash they decreased in the seed through germination periods, down to 17.75 %, 30.18 % and 5.97% respectively compared with non - germinated 20.74 % and 32.50 and 6.26% respectively. The gradually precipitated by addition of ammonium sulphate to final saturation of 30 - 90%. Agradual obvious higher specific activity of the enzyme in the precipitate resulted ,till saturation level 80% , this step gave aspecific activity of 324.40 unit/ mg protein and an enzyme yield of 29.20% ,purification folds 10.79 time. While purification step of gel filteration using Sephadex G - 100 where the specific activity 366.66 Unit / mg protein , enzyme yield of 17.83 % and purification fold 12.18. Results for determination of lipase purity showed an appearance of a single protein band by poly acrylamide gel electrophoresis with out of denaturizing agent . The molecular weight of enzyme was 41.687 kilo dalton by poly acrylamide gel electrophoresis with denaturizing agent . The optimum pH for enzymtic activity of the purified enzyme were 8 while the optimum pH stability profile of the enzyme was between 7 - 9, and the enzyme kept 90% of its activity, while notes that the optimum temperature for the enzymatic activity of the purified enzyme was 40 C ͦ, and that enzyme loses 67% of its activity at 90 C ͦ. The resulte of effectness of metal ions and reducing and chelating agent was showed that ions of mercury and zinc ions and ferrous at concentrations of ( 1 and 5 ) m M have an inhibition effect on enzyme activity, as the remaining activity reached the values 63.2 .68.9 and 66.1% respectively , while the enzyme kept its total activity at concentration of 5 m M in the presence of calcium and potassium ions. The chelating and reducing agents showed that EDTA has an active rule when the enzyme incubated with 1 and 5 mM of lipase. And it was noticed that lipase dosn΄t belong to the metalloenzyme group. For urea , it has an active rule on the enzyme activity at 1 and 5 M ,where remaining activity for the enzyme reached 86.2% when incubated with 1% 2 - mercaptoethanol while it was 74.7 and 75.8 % respectivly when incubate with 1% of Hydrogen peroxide and Sodium hydrochloride respectively. Concentration ,for enzyme kept its total activity when incubated with Triton X - 100 and Tween 20 at concentration 1%. While lipase activity did n΄t effected by adding commercial detergents, it also showed a high stability in present of Sar detergent where as residual activity reached 99.1 % . Results cleared the contrast of amino acids existin lipase because it is noticed that the highest concentration reached by leucine was 16.4% where as lowest concentration was that reached by aspartic acid 1.5% ,the other amino acids differed in their percentage . The results of pharinograph test showed that there were significant differences between the mean of water absorption the ratios showed that the concentration of 0.004 mg / 100 g flour of enzyme and 0.75% improver give highest absorption of water with significant of moral 61.7 and 59.9% respectively, while the stability period increased to 9.6 and 9.9 minutes at a concentration of 0.002 to 0.004 mg / 100 g flour of enzyme and 13.3 and 11.6 minutes at a concentration of 0.50 and 0.75% improver with significant differences. The average values of maturity period of the dough increased with increasing concentration of the enzyme 0.002 and 0.004 mg / 100 g flour with significant difference as it was 7.2 minutes and increased the maturity period of the dough at all improver concentrations of 6.8, 8.5 and 6.2, respectively, compared with the dough without any addition. Found from the final marks of sensory evaluation ,it is found that the best process was when add lipase at 0.002 mg / 100 g flour concentration and 0.5 % Ovallete ,the final marks were 95 and 94 % respectively. Its has been noticed that the values of volume of sediment in the crumb aquous suspended ,absorption power and crumb moisture, all reduced gradually with the increasing of loaf storage time. While the moisture content of crust was increased The effect of adding enzyme and improver Ovallete was positive regarding the specific characteristics of loaf such as ( volume ,color and softness of crumb) for loaf.

Dorah oil refiner and they were identified by the Vitek identification system. Four of these were Pseudomonas fluorescensand the others were Citrobacter freundii and Serratia liquefaciens. Isolate Pseudomonas fluorescens SK was chosen as the best one which can degrade phenol and its total number was262x105c.f.u.\ml.Identification of Pseudomonas fluorescens was reassured by PCR technique, also nitrogen base sequence was studied in the USA, and it was confirmed that it was belonged to Pseudomonas fluorescensas it was matched with the sequence in National Center for Biotechnology information, USA. Pseudomonas fluorescens SK has not phenol hydroxylase as it was proved by PCR and electrophoresis . Best Environmental conditions for the growth of the selected isolate (Oxygen, incubation time ,pH ,temperature and the medium) were : shaking culture 48 h ,pH 7 , 25˚C as the total bacterial numbers were : 187x104 , 275x104 , 232x104 and 271x104c.f.u.\ml. The best culture media formula was mineral media, which consists of 100 mg\L phenol, plus glucose and Yeast Extract. Highest phenol concentration which Ps. Fluorescens SK can degrade and growin was 250 mg\L as the total number was 285x105c.f.u.\ml . Phenol concentration was determined by GLC technique in bottled water was 1.99 mg\L and tap water was 1.891 - 9.721 mg\L and in untreated and biological treated industrial wastewater was ND and 12.7 mg\L, but it wasn’t detected in water samples taken from Tigris river. Synergistic action of Ps. Fluorescens SK plus a protozoa gave better results to degrade phenol as the remaining phenol was 2.12 mg\L whereas. The culture of Ps. Fluorescens SK alone gave 2.41mg\L ,and the protozoa alone 2.07 mg\L comparing to control one it was 3.1 mg\L. Heavy metals Pb, Cd, Fe, Cr, Ni and Cu were determined in untreated and biologically treated samples of Al - Dorah oil refiner industrial water also in the Tigris River samples no lead was detected in the refiner samples but it was found in Tigris samples 0.0218 mg\L. Cadmium in Tigris sample was 0.0075 mg\L and in the refiner water was 0.0086 mg\L and 0.0038 mg\L in the untreated one.

Abstract: يطلق تعبير نسجة الحنطة ويقصد به في الغالب صلابة الحبة والتي لها تاثير كبير في عملية الطحن والخبز وخواص المنتج النهائي . لقد درس دور البنتوزانات الذائبة في الماء في صلابة الحبة لكنه لازال في حاجة الى مزيد من التفسير . لقد تم استخلاص وتنقية البنتوزانات الذائبة من اربعة عشر صنفا من الحنطة المصدقة والمزروعة محليا. قدر محتوى البنتوزانات ونسبة الارابينوز الى الزايلوز ونسبةحامضي الفيروليك وثنائي الفيروليك والسكريات الاحادية. عزلت البروتينات والبنتوزانات المعاملة بالبروتيسز بواسطة الترشيح الهلامي وباستخدام هلام Sephadex G - 100 وتبع ذلك فصل الحزم البروتينية بواسطة الترحيل الكهربيElectrophoresis لتحديد الوزن الجزيئي للبروتينات المرافقة للبنتوزانات. كانت الاوزان الجزيئية للبنتوزانات والبروتينات المعزولة هي - - - 36.66 - 136.68 كيلودالتن و6.87 - >.250.000..كيلو دالتن على التوالي. لقد كشف عن وجود حزم بروتينية مرافقة للبنتوزانات المدروسة وزنها الجزيئي بحدود 14 - 16 كيلودالتن. في المرحلة الاولى من الاستخلاص بالماء كان المحتوى من البنتوزانات ونسبة الارابينوز الى الزايلوزفيهوانسبة الفيروليك ونسبة ثنائي الفيروليك هو 20.91 - 40.25% و0.51 - 1.03% و0.44 - 1.54 % و0.08 - 0.62 % على التوالي . اما البنتوزانات المعاملة بالبروتيسز فقد احتوت 23.99 - 66.01 % بنتوزانات والتي كانت نسبة الارابينوز الى الزايلوز فيهوانسبة الفيروليك وثنائي الفيروليك هي 0.35 - 0.94 و0.08 - 0.69% و0.16 - 1.19% على التوالي . وكان لبنتوزانات الترشيح الهلامي 47.35 - 86.38 % و0.09 - 1.10و 0.26 - 3.38 % و0.25 - 0.53 % بنتوزانات ونسبة الارابينوز الى الزايلوزفيهوانسبة الفيروليك وثنائي الفيروليك على التوالي. لقد بينت نتائج التحليل الاحصائي وجود علاقة ارتباط معنوية وموجبة بين صلابة الحنطة المقيسة بواسطة الاشعة تحت الحمراء NIR وثنائي فيروليك بنتوزانات الترشيح الهلامي وقيمتها* 0.603 r= .كذلك اظهرت النتائج ان بنتوزانات الترشيح الهلامي وثنائي الفيروليك له ونسبة زايلوز بنتوزانات المستخلص الاولي هي العوامل الافضل في شرح ظاهرة صلابة الحنطة . وبنفس الاتجاه فان قابلية الاحتفاظ بمحلول 50% سكروز كانت لها علاقة ارتباط معنوية وسالبة مع صلابة الحبة المقيسة بواسطة NIR .
