Redox conditions and microbial populations are intrinsically coupled in that availability of electron acceptors influences the microbial community composition and microbial processes in turn impact site geochemistry. The link between site microbiology and geochemistry then plays a governing role in the microbial metabolism and therefore the processes responsible for contaminant biodegradation. In ...

CENSUS qPCR (quantitative polymerase chain reaction) is a DNA based method to accurately quantify specific microorganisms (e.g. Dehalococcoides, Dehalobacter) and functional genes (e.g., vinyl chloride reductase, anaerobic benzene carboxylase) responsible for biodegradation of ...

Under anaerobic conditions, pentachlorophenol (PCP) can serve as an electron acceptor for some Desulfitobacterium and Dehalococcoides species. In each case however, complete reductive dechlorination of PCP to phenol was not observed. Instead, PCP dechlorination by Dehalococcoides resulted in the production of a mixture of dichloro- and monochlorophenols. Likewise, Desulfitobacterium strain PCP-1 ...

Aerobic biodegradation of MTBE and the intermediate TBA has been extensively studied in the laboratory and documented in the field. However, Methylibium petroleiphilum PM1 remains one of the few bacterial cultures isolated to date that utilizes MTBE and TBA as growth supporting substrates. The key steps in aerobic MTBE/TBA biodegradation by strain PM1 is the initial oxidation mediated by a ...

Under anaerobic conditions, chlorinated ethanes are susceptible to reductive dechlorination by several groups of halorespiring bacteria, most notably Dehalobacter and Dehalogenimonas spp., and functional genes for reductive dehalogenases continue to be identified. Anaerobic biodegradation of 1,1,2-TCA and 1,2-DCA proceeds via dichloroelimination producing vinyl chloride and ethene, respectively. ...

From 1929 to 1978, polychlorinated biphenyls (PCBs) manufactured under the commercial names like Aroclor, Fenclor, Kanechlor and Phenclor were widely used as transformer and hydraulic fluids (Field and Sierra-Alvarez 2008). Commercial PCB preparations are mixtures composed of 60 to 90 congeners with different degrees and positions of chlorine substituents. For example, Aroclor 1242, 1248, ...

At sites impacted by petroleum products or crude, the aromatic hydrocarbons benzene, toluene, ethylbenzene, xylenes (BTEX) as well as naphthalene and other polycyclic aromatic hydrocarbons (PAHs) are often the contaminants of greatest concern. However, alkanes are typically among the most abundant fractions in crude and petroleum products like gasoline and therefore significant contributors to ...

Detect and quantify bacteria responsible for biodegradation of Chlorinated Methanes. Chlorinated methanes including carbon tetrachloride (CT), chloroform (CF), and dichloromethane (DCM) were widely used as solvents, degreasers, fumigants, and chemical intermediates in industrial processes and now are common groundwater contaminants. With potential adverse health effects including increased ...
