Alpha Amylase Production by Bacillus cereus MTCC 1305 Using Solid-State Fermentation
Production of a-amylase under solid-state fermentation by Bacillus cereus MTCC 1305 has been investigated using wheat bran and rice flake manufacturing waste as substrates. With wheat bran, highest enzyme production expressed as units per mass of dry substrate ((94±2) U/g) was observed. Production parameters were optimized as inoculum size 10 % (volume per mass) and substrate:moisture ratio 1:1...
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...
متن کاملEvaluation of Ca-Independent a-Amylase Production by Bacillus sp. KR-8104 in Submerged and Solid State Fermentation Systems
This study investigates the production of crude Ca-independent and low pH active α-amylase by Bacillussp. KR-8104 in submerged fermentation (SmF) and solid-state fermentation (SSF) systems. Differentparameters were evaluated in each system using “one factor at a time” approach to improve the production ofenzyme. The results showed that in the SmF the maximum enzyme production ...
متن کاملAlpha Amylase Production by Aspergillus Oryzae Using Solid State Fermentation
A fungal strain of Aspergillus oryzae was used for the production of alpha amylase by solid state fermentation from agro-industrial waste. Enzyme production was growth associated and maximum activity (8.23 U/ml) were obtained after 120h when incubated at 30°C on wheat bran with initial moisture content 60%; initial medium pH = 5 . Enzyme activity increased when the solid medium was supplemented...
متن کاملXylanase Production under Solid State Fermentation by Aspergillus niger
Central composite orthogonal design was applied to quantify relations of xylanase production, loss of dry matter and change of pH with four critical variables during solid state fermentation of a mixture of wheat bran and wheat straw on which Aspergillus niger CCUG 33991 was cultivated. The studied variables included the percentage of wheat straw, temperature, moisture content, and fermentati...
