Fig. 2. Antagnistic effect of culture filtrate of B. methylotrophicus B18. (A) Growth inhibition curve by the B18 solution on mycelium of the pathogenic fungusError bars indicate means ± SD (n = 3); ddifferent lowercase letters indicate significant difference between controls and treatments at different times at P < 0.05 by the LSD test. (B) Antagonistic effect of the B18 bacterial solution (106 cfu/ml) against a pathogenic fungus. (C) Effect of the fermentation sterile culture filtrate on mycelial morphology of the pathogenic fungus. a: Normal mycelium; b: The concentration of biocontrol bacteria B18 is 106 cfu/ml; c: The concentration of biocontrol bacteria B18 is 108 cfu/ml. (D) Effect of the fermentation sterile culture filtrate on spores of the pathogenic fungus. a: Germination of spores at a concentration of 1%; b: Germination of spores at a concentration of 50%.
