Dehalococcoides mccartyi strain NIT01 grows more stably in vessels made of pure titanium rather than the stainless alloy SUS304

Environmental Microbiology Reports, Volume 15, Issue 6, Page 557-567, December 2023., 2023
To establish large‐scale cultivation of Dehalococcoides, 7–10 litre culturing of Dehalococcoides mccartyi strain NIT01 was performed using three different vessels made of glass, stainless alloy SUS304, and titanium. The unbreakable titanium vessel demonstrated complete dechlorination of trichloroethene (TCE) to ethene, even after being reused five ...

Presence, Diversity, and Enrichment of Respiratory Reductive Dehalogenase and Non-respiratory Hydrolytic and Oxidative Dehalogenase Genes in Terrestrial Environments

Frontiers in Microbiology, 2019
Organohalide-respiring bacteria have been linked to the cycling and possible respiration of chlorinated natural organic matter (Cl-NOM) in uncontaminated soils and sediments. The importance of non-respiratory hydrolytic/oxidative dechlorination processes

Respiratory protein interactions in Dehalobacter sp. strain 8M revealed through genomic and native proteomic analyses

Environmental Microbiology, Volume 25, Issue 11, Page 2604-2620, November 2023., 2023
Dehalobacter can respire with chlorinated methanes (chloroform) and ethanes. Genome sequencing, proteome analyses and enzymatic assays identify TmrA as the responsible enzyme. It is organized in a larger membrane‐bound respiratory complex. RdhC, a protein encoded in the same operon, appears to be another membrane‐bound electron‐transferring protein but

Bioelectrochemically-assisted degradation of chloroform by a co-culture of Dehalobacter and Dehalobacterium

Environmental Science and Ecotechnology, 2022
Using bioelectrochemical systems (BESs) to provide electrochemically generated hydrogen is a promising technology to provide electron donors for reductive dechlorination by organohalide-respiring bacteria.

Ensuring the continued success of a mulch biowall at a trichloroethylene‐contaminated superfund site: Lessons learned

Remediation Journal, Volume 33, Issue 4, Page 323-337, Fall 2023., 2023
Abstract Trichloroethylene (TCE) is a toxic organic compound, which can adversely affect human health. The chemical is one of the most frequently found contaminants in groundwater in the United States and around the world. A landfill in Maryland contaminated with high levels of TCE decades ago was added to the U.S.

Genome-Guided Identification of Organohalide-Respiring Deltaproteobacteria from the Marine Environment

mBio, 2018
Organohalide compounds are widespread in the environment as a result of both anthropogenic activities and natural production. The marine environment, in particular, is a major reservoir of organohalides, and reductive dehalogenation is thought to be an ...

Burning question: Rethinking organohalide degradation strategy for bioremediation applications. [PDF]

Microb Biotechnol
This review specifically focuses on the novel solution of organohalide bioremediation, proposing redox‐potential‐mediated hybrid bioprocesses tailored to the complexities of organohalide pollution. Abstract Organohalides are widespread pollutants that pose significant environmental hazards due to their high degree of halogenation and elevated redox ...

Comparative Genomic Analysis Reveals Preserved Features in Organohalide-Respiring Sulfurospirillum Strains

mSphere, 2022
Sulfurospirillum species strains are frequently detected in various pristine and contaminated environments and participate in carbon, sulfur, nitrogen, and halogen elements cycling. Recently we obtained the complete genome sequences of two newly isolated

Ecogenomics of microbial communities in bioremediation of chlorinated contaminated sites

Frontiers in Microbiology, 2012
Organohalide compounds such as chloroethenes, chloroethanes and polychlorinated benzenes are among the most significant pollutants in the world. These compounds are often found in contamination plumes with other pollutants such as solvents, pesticides ...

Ecophysiology and environmental distribution of organohalide-respiring bacteria

, 2016
Organohalide-respiring bacteria (OHRB) are able to breathe natural and anthropogenically produced organohalides persistent in a broad range of oxygen-depleted environments. Therefore, these microorganisms are of high interest for organohalide-contaminated site bioremediation and natural halogen and carbon cycle.
