Abstract:

Bacillus subtilis has been widely used to produce hydrolytic enzymes for various industrial applications. In this study, solid state fermentation was carried out using various agro- industrial wastes for the production of alpha amylase using B. subtilis. Among the tested agro-residues, wheat bran supported more enzyme production. The process parameters elucidated were type of substrate, incubation time, pH, moisture content of the medium, carbon source and nitrogen source. Starch (1%, w/w) and yeast extract (0.5%, v/v) were enhanced the enzyme production. Optimization of the physical parameters revealed the optimum incubation period, pH for amylase production by the isolate as 48 h and 7.0 respectively.
