Abstract EN
We aimed to isolate and identify endophytic bacteria that might have efficacy against peanut bacterial wilt (BW) caused by Ralstonia solanacearum.
Thirty-seven endophytic strains were isolated from healthy peanut plants in R.
solanacearum-infested fields and eight showed antagonistic effects against R.
solanacearum.
Strain BZ6-1 with the highest antimicrobial activity was identified as Bacillus amyloliquefaciens based on morphology, biochemistry, and 16S rRNA analysis.
Culture conditions of BZ6-1 were optimized using orthogonal test method and inhibitory zone diameter in dual culture plate assay reached 34.2 mm.
Furthermore, main antimicrobial substances of surfactin and fengycin A homologues produced by BZ6-1 were analyzed by high performance liquid chromatography electrospray ionization tandem mass spectrometry.
Finally, pot experiments were adopted to test the control efficiency of BZ6-1 against peanut BW.
Disease incidence decreased significantly from 84.5% in the control to 12.1% with addition of 15 mL (108 cfu mL−1) culture broth for each seedling, suggesting the feasibility of strain BZ6-1 in the biological control of peanut plants BW.
