Eighty-eight amylolytic Bacillus strains representing 18 species were examined for the ability to hydrolyse starch granules. Only strains of Bacillus stearothermophilus and Bacillus amylolyticus secreted amylases which showed high activity towards corn starch. The amylase from B. stearothermophilus NCA26 hydrolysed corn and wheat starch granules efficiently but had low activity on potato starch granules when the digestions were performed at 40°C; however, when the temperature was increased to 60°C, hydrolysis of potato starch granules was more effective and 45% conversion to glucose was achieved in 12 h. © 1992.
