Abstract:3-phenoxybenzoic acid (3-PBA) with estrogen toxicity is one of the intermediate products of most pyrethroid pesticides.3-PBA is difficult to degrade in the natural environment,and threatens food safety and human health.Microbial degradation of pyrethroids and their intermediate product (3-PBA) has become a hot topic in recent years.Here,we reviewed microbial species,degrading enzymes and degradation genes,degradation pathways of 3-PBA degrading and the application of 3-PBA degradation strains.This article provides references for the study of 3-PBA degradation by microorganisms.
