Amylase production from Aspergillus oryzae LS1 by solid-state fermentation and its use for the hydrolysis of wheat flour
Nine Aspergillus and three of Trichoderma strains were grown on wheat bran (WB) medium under solid state fermentation (SSF) for amylase production. Aspergillus oryzae LS1 produced the highest level of the enzyme. The thermal stability profile of its crude enzyme revealed the half-life time of more than 2 h at 50 and 60ºC. The enzyme production was affected by strain type, incubation periods, le...
متن کاملتولید باکتریایی پروتئین نوترکیب کیتیناز از باکتری ترموفیل Paenibacillus ehimensis
کیتین، دومین بیوپلیمر فراوان در طبیعت بعد از سلولز و جزء اصلی کوتیکول حشرات و پوسته سخت پوستان است و دیواره سلولی بیشتر قارچها و بعضی از جلبکها و نیز نماتدها را تشکیل میدهد. مقادیر زیادی کیتین به شکل باقیمانده تجزیه ناپذیر بدن بسیاری از جانداران وارد طبیعت میشود که باعث آلودگی محیط زیست میگردد. میتوان پس از تجزیه این پلی ساکارید با آنزیم کیتیناز از آن در جنبههای مختلف زندگی بهره جست. کیتین...
متن کاملYeast cell-surface expression of chitosanase from Paenibacillus fukuinensis.
To produce chitoorigosaccharides using chitosan, we attempted to construct Paenibacillus fukuinensis chitosanase-displaying yeast cells as a whole-cell biocatalyst through yeast cell-surface engineering. The localization of the chitosanase on the yeast cell surface was confirmed by immunofluorescence labeling of cells. The chitosanase activity of the constructed yeast was investigated by halo a...
متن کاملCytokinin production by Paenibacillus polymyxa
The production of hormones has been suggested to be one of the mechanisms by which plant growth-promoting rhizobacteria (PGPR) stimulate plant growth. To evaluate whether the free-living soil bacterium, Paenibacillus polymyxa, releases the hormone group cytokinins and, if so, their identity, the content of cytokinins in the growth media, before and after cultivation of this bacterium, was deter...
متن کاملSolid State Fermentation for Production of Chitosan by Aspergillus Niger
The effect of Solid State Fermentation (SSF) on Chitosan production by A. niger was investigated. A. niger BBRC 20004 from Biochemical and Bioenvironmental Research Centre of Sharif University of Technology (Tehran, Iran), was grown on corn residue. Chitosan was extracted from the fungal mycelia using hot alkaline and acid treatment. A. niger was incubated for 12 days on corn residue with moist...
