β-amalyse production by immobilized cells of Bacillus megaterium B6

Whole cells of Bacillus megaterium B6 were immobilized by ionotropic, thermal gelation and polymerization of which ionotropic gelation was found to be most suitable process for α-amylase production. Strontium was proved to be the best divalent cation for alginate entrapment of cell in terms of enzyme production and reusability of the cells.
