environmental protection | the catalytic efficiencies (kcat/Km) of Fluazifop-P-butyl carboxylesterase (FpbH) for different AOPP herbicides are higher than those of Cyhalofop-butyl esterase (ChbH) from Pseudomonas azotoformans and Fenoxaprop-ethyl hydrolase (FeH) from Rhodococcus sp.. FpbH differs from previously reported AOPP herbicide carboxylesterases and might be a good candidate enzyme for biodegradation, especially when diclofop-methyl and/or haloxyfop-P-methyl are the dominant pollutants | Aquamicrobium sp. FPB-1 |
