Fipronil (C12H4Cl2F6N4OS), is a commonly used insecticide effective against numerous insects and pests. Its immense application poses harmful effects on various non-target organisms as well. Therefore, searching the effective methods for the degradation of fipronil is imperative and logical. In this study, fipronil-degrading bacterial species are isolated and characterized from diverse environments using a culture-dependent method followed by 16S rRNA gene sequencing. Phylogenetic analysis showed the homology of organisms withAcinetobactersp.,Streptomycessp.,Pseudomonassp.,Agrobacteriumsp.,Rhodococcussp.,Kocuriasp.,Priestiasp.,Bacillussp.,Pantoeasp. The bacterial degradation potential for fipronil was analyzed through High-Performance Liquid Chromatography. Incubation-based degradation studies revealed thatPseudomonassp. andRhodococcussp. were found to be the most potent isolates that degraded fipronil at 100 mg L−1concentration, with removal efficiencies of 85.97 % and 83.64 %, respectively. Kinetic parameter studies, following the Michaelis-Menten model, also revealed the high degradation efficiency of these isolates. Gas Chromatography-Mass Spectrometry (GC-MS) analysis revealed fipronil sulfide, benzaldehyde, (phenyl methylene) hydrazone, isomenthone, etc., as major metabolites of fipronil degradation. Overall investigation suggests that native bacterial species isolated from the contaminated environments could be efficiently utilized for the biodegradation of fipronil. The outcome derived from this study has immense significance in formulating an approach for bioremediation of fipronil-contaminated surroundings.
