Alpha 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 degC on wheat bran with initial moisture content 60% initial medium pH 5 Enzyme activity increased when the solid medium was supplemented with additional nitrogen source (sodium Nitrate)
