Utilization of microbial community potential for removal of chlorpyrifos: a review.

Chlorpyrifos (CP) is the most commonly used pesticide in agricultural fields worldwide. Exposure to CP and its metabolites creates severe neuron-disorders in human beings. Improper handling and uncontrolled application of CP by farmers have lead to the contamination of surface and ground water bodies.

Efficacy of Aspergillus sp. for degradation of chlorpyrifos in batch and continuous aerated packed bed bioreactors.

Aerobic biodegradation of chlorpyrifos (CP) by Aspergillus sp. was investigated in batch and continuous packed bed bioreactors. The optimal process parameters for achieving the maximum removal efficiency (RE), determined using a batch bioreactor packed with polyurethane foam pieces, were inoculum level: 2.

Biodegradation of chlorpyrifos by Pseudomonas sp. in a continuous packed bed bioreactor.

Biodegradation of chlorpyrifos (CP) by Pseudomonas (Iso 1) sp. was investigated in batch as well as continuous bioreactors packed with polyurethane foam pieces. The optimum process parameters for the maximum removal of CP, determined through batch experiments, were found to be: inoculum level, 300×10(6)CfumL(-1); CP concentration, 500mgL(-1); pH 7.
