The study aims to identify bacterial strains capable of degrading chlorpyrifos and optimize their growth conditions for effective bioremediation.
Isolated bacteria from agricultural soil in Meki and Wonji-shoa using enrichment techniques.
Optimized growth conditions including pH, temperature, and chlorpyrifos concentration.
Measured bacterial growth with UV-VIS Spectrophotometer at 600 nm and chlorpyrifos degradation at 290 nm every two days.
Identified bacterial strains using biochemical characterization and 16S rRNA sequencing.
Confirmed degradation efficacy with GC-MS analysis.
Escherichia fergusonii degraded 59.34% and Clostridium bifermentans 70.82% of chlorpyrifos at initial concentration of 50 mg L−1 within 20 days.
The addition of glucose significantly enhanced degradation, achieving > 99% dissipation of the initial chlorpyrifos concentration (P < 0.05).
Optimum growth conditions were pH 5.0 and 30 °C for Clostridium bifermentans, and 35 °C for Escherichia fergusonii.

Lagiso et al. (2026) studied this question.
