The promoting effect of byproducts from Irpex lacteus on subsequent enzymatic hydrolysis of bio-pretreated cornstalks
BACKGROUND Irpex lacteus, a versatile lignin-degrading fungus with various extracellular enzymes, has been widely used for biological pretreatment. However, most studies have focused on the change of substrate structure after biological pretreatment, and the effect of these changes on the enzymatic hydrolysis, but the effect of byproducts from biological pretreatment process on subsequent enzym...
متن کاملBiodegradation of 2,4,6-Trinitrotoluene by White-Rot Fungus Irpex lacteus
White-rot fungus Irpex lacteus degraded TNT significantly in proportion to the culture time. After 48 h incubation, about 95% of TNT was degraded. Two reduced metabolites were identified as 4-amino-2,6-dinitrotoluene (4-ADNT) and 2-amino-4,6-dinitrotoluene (2-ADNT) which was further degraded.

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولPurification and Characterization of Milk Clotting Enzyme Produced by Rhizomucor Rmiehei
Milk clotting enzyme (M CE) produced by: Rhizomucor miehei was purified and characterized.The enzyme was purified 220.29-fold with specific activity about 14444.2 U/mg protein byultrafiltration, ammonium sulfate fractionation, Sephacryl S-300 chromatography. The maximumenzyme activity was at 65°C.The milk clotting activity was decreased steadily as pH is increased and indicated maximumactivity ...
متن کاملSubstrate specificity of the gastrin-amidating enzyme.
As is the case with many other peptide hormones of the brain and gut, gastrin requires a carboxyl-terminal amide moiety for optimal biological activity. In the structure of progastrin, the carboxyl-terminal Phe of gastrin is followed by the sequence Gly93-Arg94-Arg95, which must be processed sequentially by an endoprotease, a carboxypeptidase, and an amidating enzyme to produce amidated bioacti...
