Glucose content reduced quickly during 0-18 h, and then kept stable. Amido nitrogen content reached the lowest at 12 h and then rose slowly. YL001 exhibited the highest inhibitory effects at 54 h and YL002 exhibited highest inhibitory effects at 42 and 66 h respectively on B. cirerea and B. subtilis. Strains YL001 and YL002 belonged to X.
