Growth of Dehalobacter and Dehalococcoides spp. during Degradation of Chlorinated Ethanes [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACT Mixed anaerobic microbial subcultures enriched from a multilayered aquifer at a former chlorinated solvent disposal facility in West Louisiana were examined to determine the organism(s) involved in the dechlorination of the toxic compounds 1,2-dichloroethane (1,2-DCA) and 1,1,2-trichloroethane (1,1,2-TCA) to ethene ...

Tetrachloroethene respiration in Sulfurospirillum species is regulated by a two‐component system as unraveled by comparative genomics, transcriptomics, and regulator binding studies

MicrobiologyOpen, Volume 9, Issue 12, December 2020., 2020
Organohalide‐respiring bacteria need to sense halogenated hydrocarbons in the environment to induce the production of the enzymatic machinery required for their utilization. Identification and characterization of biological sensors for organohalides, such as the two‐component system described here, could guide synthetic approaches for monitoring ...

Microbial degradation of halogenated aromatics: molecular mechanisms and enzymatic reactions

Microbial Biotechnology, Volume 13, Issue 1, Page 67-86, January 2020., 2020
This minireview discusses the molecular mechanisms of the enzymatic reactions for degrading halogenated aromatics which naturally occur in various microorganisms. An in‐depth understanding of how microbes employ various enzymes in biodegradation can lead to the development of new biotechnologies via enzyme/cell/metabolic engineering or synthetic ...

Reductive dechlorination of β-hexachlorocyclohexane (β-HCH) by a Dehalobacter species in coculture with a Sedimentibacter sp. [PDF]

FEMS Microbiology Ecology, 2005
An anaerobic coculture was enriched from a hexachlorocyclohexane (HCH) polluted soil. The coculture reductively dechlorinates the beta-HCH isomer to benzene and chlorobenzene in a ratio of 0.5-2 depending on the amount of beta-HCH degraded. The culture grows with H(2) as electron donor and beta-HCH as electron acceptor, indicating that dechlorination ...

Modeling reveals metabolic basis of competition among Dehalobacter strains during tandem CF and DCM metabolism

bioRxiv
SC05-UT is an anaerobic mixed microbial enrichment culture that reduces chloroform (CF) to dichloromethane (DCM) through reductive dechlorination, which it further mineralizes to carbon dioxide.

Reductive Dehalogenation of Trichloromethane by Two Different Dehalobacter restrictus Strains Reveal Opposing Dual Element Isotope Effects.

Environmental Science and Technology, 2019
Trichloromethane (TCM) is a frequently detected and persistent groundwater contaminant. Recent studies have reported that two closely related Dehalobacter strains (UNSWDHB and CF) transform TCM to dichloromethane, with inconsistent carbon isotope effects

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater

Groundwater Monitoring &Remediation, Volume 46, Issue 2, Page 44-54, Spring 2026.
Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.

Impact of Anaerobic Cold Storage on Subseafloor Microbial Communities

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Sediment cores recovered from the deep sea often cannot be sampled for microbiological analysis immediately due to the need for core splitting and processing for subsequent onboard measurements and core storage. Consequently, sections are often stored at 4°C under anaerobic conditions for extended periods.
