摘要
Abstract
The central composite design combined with response surface methodology was employed to optimize the protoplast formation conditions of Bacillus subtilis BS-1101.The critical parameters,such as lysozyme concentration,temperature,and contact time which affects the formation of protoplast of the Bacillus subtilis BS-1101 were studied using a novel technique named response surface methodology.Second-order multiple regression analysis was used to build a predicted model of the combined effects of independent variables(enzyme concentration,temperature and effect time) for maximum the yield of protoplast of Bacillus subtilis BS-1101.The optimal parameters to obtain the highest protoplast yield were as followed: temperature was 37.27 ℃,effect time was 88.8min,enzyme concentration was 5.152 mg·mL-1.The average experimental protoplast yield under the optimum conditions was found to be 77.02%,which agreed with the predicted value.The proposed method showed high degree of reproducibility.The central composite design was employed to optimize the protoplast formation conditions of Bacillus subtilis BS-1101.关键词
