Comparative Analysis Of Alpha-Amylase Activities Of Different Bacillus Species Isolated From Various Compost Materials And Process Optimization

This work has been carried out for the isolation of different Bacillus species isolated from various compost materials and their a -amylase activites were optimized and compared. Different compost materials such as agriculture compost, garbage waste and vegetable waste were selected for isolation of Bacillus species on the basis of their morphological and biochemical characteristics. Out of ten Bacillus species, four species were selected on the basis of amylase test. Among these four species, Bacillus coagulans showed the highest amount of amylase activity of 8.4 U/ml at 35 degrees C and pH 7.0 after 24 h incubation period.
