Abstract

An amylase produced by a Bacillus sp (accession number A721 in the CFTRI Culture Collection) was purified and characterized. The purified 80 kDa protein of pI 5.1 was able to dextrinize starch, glycogen and pullulan. Temp. and pH optima of the enzyme were 60C and 6.6, respectively, and, in the presence of 0.05M CaCl2, the enzyme retained stability for 15 min at 80C. Antibodies raised to the amylase showed no reaction with alpha-amylases of Bacillus sp. and B. licheniformis. In culture, proteolytic degradation of the enzyme was observed.
