From mec cassette to rdhA: a key Dehalobacter genomic neighborhood in a chloroform and dichloromethane-transforming microbial consortium. [PDF]

Appl Environ Microbiol
Chloroform (CF) and dichloromethane (DCM) are groundwater contaminants of concern due to their high toxicity and inhibition of important biogeochemical processes such as methanogenesis.

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 ...

A Novel Dehalobacter Species Is Involved in Extensive 4,5,6,7-Tetrachlorophthalide Dechlorination [PDF]

Applied and Environmental Microbiology, 2009
ABSTRACT The purpose of this study was the enrichment and phylogenetic identification of bacteria that dechlorinate 4,5,6,7-tetrachlorophthalide (commercially designated “fthalide”), an effective fungicide for rice blast disease. Sequential transfer culture of a paddy soil with lactate and fthalide produced a soil-free enrichment

Reductive Dechlorination of 2,3-Dichloroaniline by <i>Dehalobacter</i> in an Anaerobic Enrichment Culture. [PDF]

Environ Sci Technol
2,3-dichloroaniline (2,3-DCA) has widespread use in chemical manufacturing and remains a persistent groundwater contaminant. To better understand the pathway and kinetics of its reductive dechlorination, we conducted a laboratory kinetic experiment using an anaerobic enrichment culture dominated by Dehalobacter.

Resilience and functional redundancy of methanogenic digestion microbiome safeguard recovery of methanogenesis activity under the stress induced by microplastics

mLife, Volume 2, Issue 4, Page 378-388, December 2023., 2023
Abstract Microplastics and nanoplastics are emerging pollutants that substantially influence biological element cycling in natural ecosystems. Plastics are also prevalent in sewage, and they accumulate in waste‐activated sludge (WAS). However, the impacts of plastics on the methanogenic digestion of WAS and the underpinning microbiome remain ...

Field Test of a Bioelectrochemical Membrane-Less Reactor for Chlorinated Aliphatic Hydrocarbon and Nitrate Removal from a Contaminated Groundwater. [PDF]

Chempluschem
This study evaluates a membrane‐less bioelectrochemical reactor in a real groundwater remediation scenario, targeting chlorinated aliphatic hydrocarbons and nitrate contamination. Electron supply via graphite granules biocathode stimulates reductive dechlorination and nitrate reduction, despite competing processes like sulfate reduction and ...

Trichloromethane dechlorination by a novel Dehalobacter sp. strain 8 M reveals a third contrasting C and Cl isotope fractionation pattern within this genus.

Science of the Total Environment, 2021
Trichloromethane (TCM) is a pollutant frequently detected in contaminated aquifers, and only four bacterial strains are known to respire it. Here, we obtained a novel Dehalobacter strain capable of transforming TCM to dichloromethane, which was ...

Responses of Anabaena sp. PCC7120 to lindane: Physiological effects and differential expression of potential lin genes

MicrobiologyOpen, Volume 12, Issue 3, June 2023., 2023
In this article, the tolerance of Anabaena sp. to lindane was studied as well as the expression of its potential lin genes. Our goal was to obtain information to create strategies for lindane bioremediation and also to find the induction of genes in the presence of lindane that can be used in the development of whole‐cell biosensors.

Growth- and substrate-dependent transcription of formate dehydrogenase and hydrogenase coding genes in Syntrophobacter fumaroxidans and Methanospirillum hungatei [PDF]

, 2011
Transcription of genes coding for formate dehydrogenases (fdh genes) and hydrogenases (hyd genes) in Syntrophobacter fumaroxidans and Methanospirillum hungatei was studied following growth under different conditions.
