Microbial degradation of tetrachloromethane: mechanisms and perspectives for bioremediation

Abstract: Toxic man-made compounds released into the environment represent potential nutrients for bacteria, and microorganisms growing with such compounds as carbon and energy sources can be used to clean up polluted sites. However, in some instances, microorganisms contribute to contaminant degradation without any apparent benefit for themselves. Such cometabolism plays an important part in bioremediation, but is often difficult to control. Microbial degradation of tetrachloromethane (carbon tetrachloride, CCl(4)), a … Show more

“…Genetic engineering of Deinococcus radiodurans (radiation resistant bacterium) which naturally reduces Cr (IV) to Cr (III) has been done for complete toluene (fuel hydrocarbon) degradation by cloned genes of tod and xyl operons of Pseudomonas putida [90]. Microbial metabolites like metal bound coenzymes and siderophores mainly involved the degradation pathway [91].…”

“…Abiotic degradation of CCl 4 has been observed in the presence of metal and sulfur-containing compounds (6,19,58), including reductive dechlorination under aerobic conditions (35). Biotic removal of CCl 4 has been documented for a variety of anaerobic bacteria (18,32,34,47,67), with the products of degradation varying depending on the redox conditions and type of bacteria mediating the reaction (5,13,14,46,67). Although sulfate-reducing conditions have been shown to enhance CCl 4 transformation in anaerobic column experiments, in some experiments sulfate reducers themselves did not play a role, as evidenced by a lack of inhibition upon amendment with molybdate (13,14).…”

“…Methane (CH 4 ) (5%) was added to soil samples to stimulate methanotrophy (15). Methanol was added to stimulate methylotrophy (1), and the multicarbon compounds acetate and succinate were added, which would have been available for use by various organisms, including facultative methylotrophs (3); these compounds could also act as electron donors for reductive dehalogenation (28,31,46 …”

“…by magnetite) initiates with a reduction and leads, after different steps including hydrolysis, to formate, CO and CO 2 as final products. CT "thiolytic reduction", after an initial reduction, produces CS 2 as final product by thiolytic substitution of dechlorinated intermediates, being mediated either by Fe(II)-sulfides or by bacteria (Field and SierraAlvarez, 2004;Penny et al, 2010;Koenig et al, 2012;He et al, 2015). CT reduction by Pseudomonas stutzeri also produces CO 2 as the final product, with transient accumulation of toxic phosgene and thiophosgene (Lewis and Crawford, 1995).…”
