| Abstract: | Kinetics analysis for inhibition of a Bacillus natto strain against Escherichia coli in vitro was studied.The effects of medium composition to the growth rate and antibacterial capability were investigated.Through orthogonal experiment the medium that could inhibit Streptococcus aureus was optimized and its composition was:2% lactose,4% peptone,0.2% Na2HPO4,and 0.2% Glycine. |

| Keywords: | Bacillus natto inhibition in vitro growth rate medium optimization |
