ABSTRACT

Seven different bacterial strains were isolated from spent mushroom substrate (SMS) and tested for starch hydrolysis. Out of them, three bacterial strains namely Bacillus spp (B1), Pseudomonas spp, Bacillus spp (B2) were able to form clear zone in starch hydrolyzing medium. These three strains were subjected for amylase assay and extra cellular amylase production was observed as 214,180 and 245g/ml respectively.

Keywords : SMS, Starch hydrolysis, Bacillus, Pseudomonas, extra cellular amylase.
