title: Isolation and identification of alpha-amylase producing Bacillus sp. from dhal industry waste.
abstract: A bacterial strain was isolated from dhal industry red gram waste and identified as Bacillus. A thermostable extracellular amylase was partially purified from the strain. Optimum temperature and pH for the enzyme were found to be 60 degrees C and 6.5, respectively. The maximum amylase production was achieved with maltose as carbon source. Among the nitrogen sources, peptone and yeast extract produced maximum amylase.
