THE ANTAGONISTIC ACTIVITY OF ONE B. SUBTILIS MUTANT BS9920 IN VITRO

摘要

The antagonistic activity of one B.subtilis mutant named BS9920 on three strains of common pathogens was investigated.The assay of three consecutive days showaed that this mutant could significantly inhibit the growth of three kinds of commom infectious pathogens Staph lococcus,aureus,Pseudomonas aeruginosa and Pathogenic Escherichia coli and superior to the capability of BS224.This study indicated that BS-9920 possessed strong antagonistic effect in vitro .
