Degradation of 1,2-dichloroethane by Ancylobacter aquaticus and other facultative methylotrophs
Article Abstract:
New strains of Ancylobacter aquaticus capable of growing on 1,2-dichloroethane (DCE) as the sole carbon and energy source were isolated. The three strains, designated as AD20, AD25 and AD27, were facultative methylotrophs capable of utilizing DCE, 2-chloroethanol, chloroacetate and 2-chloropropionate. Studies on DCE degradation showed that the three strains and three other newly described strains of DCE degraders, followed the same pathway of DCE degradation, but differed in the regulation ofthe enzymes involved. Sequence analysis of dhlA, which codes for haloalkane dehalogenase showed that the dhlA coding regions are conserved among different species.

Multiphasic kinetics of transformation of 1,2,4-trichlorobenzene at nano- and micromolar concentrations by Burkholderia sp. strain PS14
Article Abstract:
The transformation of 1,2,4-trichlorobenzene (TCB) by Burkholderia sp. strain PS14 begins at a first-order relationship between transformation rate and substrate concentration at low concentrations of 1,2,4-TCB. As substrate concentration increases, the reaction shifts to a second-order relationship.
