Production of a high-efficiency cellulase complex via β-glucosidase engineering in Penicillium oxalicum.
BACKGROUND Trichoderma reesei is a widely used model cellulolytic fungus, supplying a highly effective cellulase production system. Recently, the biofuel industry discovered filamentous fungi from the Penicillium genus as a promising alternative to T. reesei. RESULTS In our study, we present a systematic over-expression analysis of nine β-glucosidase encoding genes in the wild-type strain 114...
متن کاملFunctional diversity and properties of multiple xylanases from Penicillium oxalicum GZ-2
A multiple xylanase system with high levels of xylanase activity produced from Penicillium oxalicum GZ-2 using agricultural waste as a substrate has been previously reported. However, the eco-physiological properties and origin of the multiplicity of xylanases remain unclear. In the present study, eight active bands were detected using zymography, and all bands were identified as putative xylan...
متن کاملextraction 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 اولPurification of an acid alpha-glucosidase by dextran-gel filtration.
1. The behaviour of rat liver alpha-glucosidases on dextran gel (Sephadex G-100) columns was studied. A ;retardation' of an acid alpha-glucosidase activity was observed. This activity was identified as lysosome alpha-(1-->4)-glucosidase. A single gel-filtration step resulted in a 700-fold purification of the enzyme. The same technique was also used to purify the acid alpha-glucosidase of human ...
متن کاملPurification and Properties of an Inducible p-Glucosidase of Yeast*
In the past decade considerable advances have been achieved in the study of induced enzyme biosynthesis in microorganisms. A comparison of three of the better studied systems, P-galactosidase in Escherichia coli (l), penicillinase in Bacillus cereus (2), and oc-glucosidase in Xaccharomyces cerevisiae (3) indicates that there are a number of differences in these inductions. In order to compare f...
