Abstract:
One biocontrol bacillus B3 was isolated from peanut rhizosphere, which showed a broad inhibition spectrum against various soil-borne plant phytopathogenic fungi. It was also found to be capable of utilizing beta-cypermethrin, chlorpyrifos and imidacloprid as the sole source of carbon for growth. The extent of degradation of them at initial concentration of 100 mg/L was 54.42%, 57.44% and 49.24% respectively within 7 days. Strain B3 was identified as Paenibacillus polymyxa based on morphological, physiological-biochemical properties, and 16S rRNA sequence analysis. This study indicated that strain B3 had potential application in biological control and soil bioremediation.
