Difenoconazole, as a systemic triazole fungicide, is broad-spectrum, highly effective agent that has been widely used for controlling fungal diseases in 46 different crops (or crop categories), including rice, wheat, and corn. Due to the improper use of difenoconazole, concerns about its environmental residues toxicity non-target organisms have drawn significant attention from researchers. In response this issue, study aimed isolate microbial strains capable degrading difenoconazole environment. A novel difenoconazole-degrading strain, Acinetobacter sp. A-1, was screened identified, demonstrating ability degrade 62.43% 50 mg/L within seven days. Further optimization degradation conditions conducted using single-factor experiments surface methodology experiments. The results showed optimal strain A-1 were concentration 55.71 mg/L, pH 6.94, an inoculation volume 1.97%, achieving rate 79.30%. Finally, immobilized sodium alginate, stability bioremediation efficiency evaluated. indicated exhibited high significantly reduced half-life water–sediment contamination system. sterilized system, by reached 65.26%. Overall, suggests promising candidate degradation, immobilization technology can effectively enhance removal systems.
