The error bars represent the standard deviation. For each incubation time, the different letters indicate significant differences (P < 0.05). CK: control soil without bacteria or nematodes; B: soil inoculated with B. megaterium JX 15; N1: soil inoculated with the isolated Cephalobus sp.; N2: soil inoculated with the isolated Mesorhabditis sp.; BN1: soil inoculated with B. megaterium JX 15 and the Cephalobus sp.; and BN2: soil inoculated with B. megaterium JX 15 and the Mesorhabditis sp.
