Abstract

Chlorpyrifos a widely used organophosphate pesticide poses significant environmental hazards due to its persistence, toxicity and efficiency in contaminating soil and water resources. The urgent need for effective remediation strategies has led to increased interest in microbial bioremediation which utilizes the natural ability of microorganisms to degrade environmental pollutants. This study aimed to isolate and characterize chlorpyrifos degrading bacteria from the paddy field soil. Soil sample was collected from chlorpyrifos-treated fields and subjected to enrichment culture technique. The resulting bacterial isolates were screened for their degradation capabilities to assess their ability to metabolize chlorpyrifos. Based on the pesticide degradation potential, one isolate, PDB-1 was selected for further molecular characterization using 16S rRNA gene sequencing. This analysis revealed that among the chlorpyrifos-degrading bacterial community, Acinetobacter baumannii demonstrated significant pesticide degradation activity. The findings of this research enhance our understanding of microbial pathways involved in chlorpyrifos degradation and contribute to the development of sustainable bioremediation strategies for contaminated agricultural environments.
