analysis of the effects of carbon source, nitrogen source, and metal ions on cell growth and Bacillus aryabhattai beta-amylase production in recombinant Brevibacillus choshinensis. The optimal medium contains 7.5 g/l glucose, pig bone peptone (40.0 g/l), Mg2+ (0.05 mol/l), and trace metal elements, the beta-amylase yield reaches 925.4U /ml, which is 7.2fold higher than that obtained in the initial medium. A modified feeding strategy is proposed and applied in a 3-l fermentor fed with glucose achieving a dry cell weight of 15.4 g/l. Through this cultivation approached 30°C with 0 g/l initial glucose concentration, the maximum beta-amylase activity reaches 5371.8 U/ml which is 41.7fold higher than that obtained with the initial medium. Cell growth and protein synthesis reach a balance at 30°C
