Carbon tetrachloride (CT) is a carcinogenic, ozone-depleting, toxic, xenobiotic compound found in ground water, listed as a priority pollutant by the US EPA. In aqueous solution, CT is not readily hydrolyzed and has an estimated half-life of 7,000 years. Since CT resists spontaneous degradation, conditions favorable for dehalogenation must be created to effect remediation of CT contamination. This paper describes studies of CT transformation aimed at determining the potential of Pseudomonas sp. strain KC as a bioaugmentation strain and describes a search for KC-type CT transformation activity in samples from regional aquifers. 11 refs., 9 figs., 1 tab.
