Profenofos pesticide removal by microbial degradation

What is it about?

The current study investigated the integrated bioaugmentation and biostimulation techniques to boost the performance of profenofos pesticide removal. Profenofos bioremediation under stimulated (focusing on additional carbon supplement) condition was carried out. To mimic the condition applying the field, column experiment was performed for demonstrating profenofos remediation under different infiltration rates and cell numbers. Profenofos biodegradation intermediate product was also monitored for profenofos biodegradation pathway prediction. The remediation potential result and proposed degradation pathway from this work could be used as fundamental knowledge for future application.

Why is it important?

Profenofos, one of organophosphorus pesticides (OPP) generally used for pest control in agricultural purpose, has been reported contamination in water. Previous studies related to profenofos biodegradation focused on the enrichment of the degrading cultures. So far, the study on the enhancement of profenofos bioremediation has never been reported. The current study successfully achieved the enhancement of profenofos removal performance using integrated bioaugmentation and biostimulation techniques.
