Screening,Identification and Optimization of Fermentation Condition of an Antagonistic Bacteria Against Ginseng Rusted Root Caused by Cylindrocarpon destructans
One antagonistic bacterial strain ATB4 was isolated from the rhizosphere soil samples of healthy ginseng.Based on phylogenetic analyses of 16S rDNA and gyrA gene sequences, and morphological, physiological, biochemi-cal characterizations, the strain ATB4 was identified as Bacillus methylotrophicus. The single factor experiment andorthogonal experiment were adopted to optimize the liquid fermentation medium and conditions that enhance its bio-control efficacy against Cylindrocarpon destructans caused ginseng...
