extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولExopolysaccharides from Pleurotus pulmonarius: Fermentation Optimization, Characterization and Antioxidant Activity
Culture conditions for exopolysaccharide (EPS) production by Pleurotus pulmonarius in submerged culture are optimized. The suggested medium composition was as follows: 60 g/L of xylose, 6 g/L of soy extract, 5 mM of KH2PO4 and 5 mM of MgSO4. Under the optimized culture conditions in a 5-litre stirred tank fermentor, the maximum concentration of EPS was 6.36 g/L. Furthermore, the morphological p...
متن کاملFusarium incarnatum/equiseti hemodialysis graft infection
Hemodialysis graft infections typically occur as a result of contamination by skin flora at the time of insertion or become secondarily infected after high-grade bacteremia. Infection of implanted vascular devices with filamentous fungi is rare. We report a case of infection of an implanted polytetrafluoroethylene dialysis graft with Fusarium incarnatum/equiseti that did not grow in cultures of...
متن کاملAntibiotic produced by Fusarium equiseti NRRL 5537.
Fusarium equiseti NRRL 5537 grown on an autoclaved white corn grit medium for 3 to 4 weeks at room temperature produced a substance in excess of 5 g/kg of substrate that inhibited some gram-positive bacteria including mycobacteria. Most Bacillus subtilis, Mycobacterium phlei, and Staphylococcus aureus strains were inhibited when 1 mug of the antibiotic per ml was incorporated into the culture m...
متن کاملScreening of Lovastatin Production by Filamentous Fungi
In the present study, 110 fungal strains of Persian Type Culture Collection (PTCC) including some selected strains isolated in various screening projects were tested for their potentiality to produce lovastatin, a competitive inhibitor of 3-hydroxy-3-methylglutaryl-CoA reductase (HMG-CoA reduc-tase), the rate-limiting enzyme of cholesterol biosynthesis. The fungal strains were cultivated in a t...
