Abstract: In order to verify probiotic properlies of candidate strain, put selected NL0908 LactobaciUus acidophilus from calf origin into experiment of bacteriostasis in vitro, through co-culture and supernatant bacteriostatic test, it found that NL0908 strain pathogenic hadantibacterial activity to Escherichia coll. thermal, proteinase treatment and neutralization with supematant, it proved that antibacterial substance may combined action organic acid and mini-peptides of antimicrobial substance.
