Butachlor is a widely utilized acetamide herbicide noted for its systemic selectivity against pre-emergence grass weeds. has negative effects on organisms and the environment, so it necessary to screen degradation strains. In this investigation, Bacillus cereus strain DC-1 was isolated from soil persistently exposed butachlor. Through rigorous single-factor response surface analyses, exhibited notable 87.06% efficiency under optimized conditions where temperature 32.89 °C, pH 7.29, inoculum concentration 5.18%. It further hypothesized by LC-MS that pathway of butachlor might be as follows: undergoes initial deoxygenation catalyzed dioxygenases form 2-chloro-N-(2,6-diethylphenyl)-N-methylacetamide, followed N-demethylation yielding 2-chloro-N-(2,6-diethylphenyl) acetamide, culminating in conversion 2,6-diethylphenol. addition, bioremediation experiments butachlor-contaminated were conducted. The results show could degradable 99.23% (100 mg·kg−1) within 12 d, sucrase, cellulase, urease activities are promoted bacteria. And through high-throughput sequencing, concluded able influence relative abundance certain bacteria soil, make microbial community develop more stable beneficial direction. thus represents valuable resource realm due robust efficacy, favorable characteristics, ecological restorative capabilities, underscoring promising role soils.
