Inhibitory effect of ethyl acetate extract and methanol extract of the cell-free filtrate of X. neamatophila YL001 at different initial pH on B. subtilis (A) and B. cinerea (B). The inhibitory effect of X. nematophila YL001 culture on B. subtilis is presented as antibiotic activity which was expressed as units of activity per mL of the cell-free filtrate generated as described in “Methods”. The inhibitory effect of X. nematophila YL001 culture on B. cinerea is presented as inhibition rate which was calculated described in “Methods”. Data are presented as the averages ± the standard deviations for six replicates. Different lower case letters above the bars indicate significant differences at P = 0.05
