Biodegradation of chlorpyrifos by soil bacteria and their effects on growth of rice seedlings under pesticide-contaminated soil

This study identified three soil bacteria (NRRU-BW3, NRRU-BW3, and NRRU-TV11) that degrade chlorpyrifos, produce indole-3-acetic acid, exopolysaccharides under pesticide stress. The results revealed were as Priestia megaterium Bacillus siamensis NRRU-BW9, amyloliquefaciens NRRU-TV11. These strains showed the ability to acid (IAA) (EPS) in chlorpyrifos. Moreover, these can chlorpyrifos (CP) an aqueous medium, and a 33–52% degradation rate was observed after 14 days of incubation. Inoculation with NRRU-TV11 significantly increased (P < 0.05) plant height, root length, biomass vigour index rice seedlings compared uninoculated controls chlorpyrifos-contaminated soil. findings demonstrated beneficial effects indigenous on seedling development recommended this strain potential replacement for growth improvement environmental bioremediation pesticide-contaminated agricultural soils.
