Bacterial Cytochrome P450 Involvement in the Biodegradation of Fluorinated Pyrethroids.

ABSTRACT: Fluorinated pyrethroids, such as cyfluthrin and cyhalothrin, are more effective insecticides due to their enhanced stability and lipophilicity. However, they pose greater risks to non-target organisms. Their persistence in the environment and accumulation in tissues can lead to increased toxicity and ecological concerns. This study investigates the biodegradation of the fluorinated pyrethroids β-cyfluthrin (BCF) and λ-cyhalothrin (LCH) using a newly isolated Bacillus sp. MFK14 from a garden soil microbial consortium. Initial screening using ¹⁹F NMR analysis showed that the microbial consortium degraded both pyrethroids, leading to the isolation of Bacillus sp. MFK14. Subsequent GC-MS analysis revealed various degradation intermediates in both pyrethroids after incu
