Characterization of an isolate that uses vinyl chloride as a growth substrate under aerobic conditions
Article Abstract:
A strain of Pseudomonas aeruginosa has been identified that can biodegrade vinyl chloride. Unlike other microorganisms that lose their ability to degrade vinyl chloride when grown in its absence, this strain resumed degrading the chemical when grown without it for at least 24 days.

Involvement of linear plasmids in aerobic biodegradation of vinyl chloride
Article Abstract:
Linear plasmids were analyzed to study the pathway for Vinyl Chloride (VC) biodegradation in strains AJ and TD and explain why this process happens at many sites but not in all sites where groundwater is contaminated with chloroethenes. The study illustrated that the metabolism of VC as the sole source of carbon and energy under aerobic conditions by the two isolates got from two distinct hazardous waste sites is due to linear megaplasmids.

Reduction and acetylation of 2,4-dinitrotoluene by a Pseudomonas aeruginosa strain
Article Abstract:
A Pseudomonas aeruginosa strain isolated from a wastewater treatment plant transforms 2,4-dinitrotoluene to produce 4-amino-2-nitrotoluene (4Am2NT) and 2-amino-4-nitrotoluene (2Am4NT). Gradual transformation of 4Am2NT and 2Am4NT leads to small amounts of 2,4,diaminotoluene (DAT). The biotransformation is reductive and is characteristic of the reactions that occur in the presence of an easily degradable carbon source. The transformation reaction involves the acetylation of arylamines specially at the position para to the methyl group. The acetylation of DAT is much faster than the abiotic transformation.
