In recent years, interest has increased degradation of hazardous contaminants in situ by stimulating selected bacterial populations or by addition of novel organisms to contaminated sites. Advantages of introduced organisms include extensive study in the laboratory which improves prospects for control of their activities in the field. Chloroform (CF) is a common end product of carbon tetrachloride (CT) but is more presistant and is a suspected carcinogen. Metabolic pathways that do not produce CF are of interest. This study reports on the kinetics of CT transformation by Pseudomonas sp. strain KC and describes experiments to evaluate the role of trace metals in CT transformation kinetics. Evidence is provide that accelerated CT transformation can be obtained in iron-rich ground waters and soil slurries by adding strain KC after pH adjustment. 9 refs., 9 figs., 1 tab.
