Enantioselective Degradation of 2, 4-Dichlorprop Methyl Ester by Sediment Bacteria
淤泥优势菌对手性农药2,4-滴丙酸甲酯的对映体选择性降解

Enantioselective Degradation of 2,4-Dichlorprop methyl ester was studied by sediment bacteria.One DCPPM-degrading bacteria stain was isolated from contaminated sediments. The EF values were determined by chiral GC. The enantioselectivity of DCPPM biodegradation in aquatic phases were evaluated. Incubation with DCPPM-degrading bacteria show that the R enantiomer was preferentially degraded over the corresponding S enantiomer of DCPPM. The EF values show a much higher deviation. It indicate that the microbial degradation of DCPPM was enantioselectivety.
