Isolation, Identification and Activity of an Antagonistic Spore Bacterium against Cotton Verticillium Wilt
摘要
Abstract
A bacterial strain called Z-5 that had strong inhibition capability against Verticillium dahliae V-190 was obtained via preliminary and secondary screening with the improved agar plate diffusion method. Characterized by morphological and cultural features observation, physiological and biochemical experiments, and 16S rDNA sequence analysis, the Z-5 strain was initially identified as Bacillus malacitensis. Control of cotton Verticillium wilt by this antagonistic bacterium was assessed via potted plants. Results showed that the control efficacy of the antagonistic Z-5 strain on cotton Verticillium wilt was 76.05%. Preliminary results demonstrated that the antagonistic Z-5 bacterial strain could significantly inhibit the growth of V. dahliae.关键词
