Fifty seven rhizobacteria were isolated from rhizospheric soil of wilted tomato plants and among them two strains of rhizobacteria, having better antagonistic and plant growth promoting ability were characterized them as Bacillus amyloliquefaciens DSBA-11 and DSBA-12 based on morphological, biochemical, partial gene sequence analysis of 16S rRNA and fatty acid methyl ester analysis. Antagonistic activity of these strains DSBA-11, DSBA-12 was compared with other Bacillus species such as B. subtilis DTBS-5, B. cereus JHTBS-7, B. pumilus MTCC-7092 strains, against Ralstonia solanacearum race 1, bv 3, phylotype I, inciting bacterial wilt of tomato underin vitro conditions. B. amyloliquefaciens DSBA-11 showed maximum growth inhibition of R. solanacearum (4.91cm2) followed by strains DSBA-12 (3.31cm2) and B. subtilis (3.07 cm2). Moreover, strains DSBA-11 wa.. View More»
