[Enantioselective degradation of 2, 4-dichlorprop methyl ester by sediment bacteria].
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.
