Characterization of polychlorinated alkane mixtures--a Monte Carlo modeling approach.

abstract：:A coryneform bacterium that is able to utilize cis- and trans-3-chloroacrylic acid as sole carbon source for growth was isolated from freshwater sediment. The organism was found to produce two inducible dehalogenases, one specific for the cis- and the other for trans-3-chloroacrylic acid. Both dehalogenases were purif...
