Characterization of a methane-utilizing bacterium from a bacterial consortium that rapidly degrades trichloroethylene and chloroform
Article Abstract:
A mixed culture of bacteria was grown in a bioreactor with methane as the sole carbon and energy source. Characterization of the microbial populations showed that the predominant organism was similar to bacteria of the genus Methylosinus. These bacteria werecapable of rapid transformations of trichloroethylene and produced soluble methane monooxygenase. Therefore, the results showed that a type II methanobacterium related to Methylosinus is responsible for the oxidation of trichloroethylene via the action of a soluble methane monooxygenase.

Degradation of dicamba by an anaerobic consortium enriched from wetland soil
Article Abstract:
Dicamba is a chemically stable postemergence herbicide which exists primarily in dissociated anionic form and is thus highly mobile and susceptible to dispersal through runoff and leaching. The degradative pathway of dicamba was elucidated using a methanogenic dicamba-degrading consortium enriched from wetland soil. The results showed that dicamba is first demethylated, forming 3,6-dichlorosalicylica acid, which is then dechlorinated reductively to form 6-chlorosalicylic acid.

Enrichment and molecular characterization of a bacterial culture that degrades methoxy-methyl urea herbicides and their aniline derivatives
Article Abstract:
Soil that contains herbicides can become enriched with bacteria that can degrade the herbicide. This was documented by a researcher who found high biodegradation activity in soil treated with linuron for more than 10 years but no biodegradation activity in untreated soil at the same location. The bacteria could not be cultured, but were detected by DGGE.
