摘要：

In this paper, the sterilization of surfactin and fengycin to Bacillus cereus was observed, and the optimization of the inactivation of surfactin and fengycin to spores of B. cereus by a response surface methodology was studied. Results showed that surfactin and fengycin had high sterilization to B. cereus, whose minimal inhibitory concentration was 31.25 mu M and 62.5 mu M respectively. The optimization result indicated that spores of B. cereus could be inactivated by two orders of magnitude when the temperature was 20.41 degrees C, the action time was 21.13 h, and the concentration (surfactin/fengycin molar ratio 1:1) was 54.20 mu M.
