Frequent concomitant presence of Desulfitobacterium spp. and " Dehalococcoides ” spp. in chloroethene-dechlorinating microbial communities [PDF]

, 2018
The presence of chloroethene dechlorination activity as well as several bacterial genera containing mainly organohalide-respiring members was investigated in 34 environmental samples from 18 different sites.

Biogeochemical characterization of micritized carbonate grains in the shallow‐marine Al‐Kharrar Lagoon (Red Sea, Saudi Arabia)

Sedimentology, Volume 72, Issue 5, Page 1593-1619, August 2025.
ABSTRACT Micritization of marine carbonate grains is an early diagenetic process involving the alteration of the original carbonate fabric and the formation of cryptocrystalline textures through cycles of dissolution and reprecipitation. Microorganisms play a significant role in this process, actively contributing to the formation of constructive and ...

Heavy Metal Remediation: A Sustainable Approach

Applied and Environmental Soil Science, Volume 2025, Issue 1, 2025.
With an emphasis on bioremediation as a crucial approach to mitigate the detrimental effects of heavy metals (HMs), this study explores the causes of HM pollution, their impact on the environment and human health, and remediation techniques. In contrast to traditional physical and chemical methods, bioremediation offers a more economical, less toxic ...

Microbiome dynamics of a polychlorobiphenyl (PCB) historically contaminated marine sediment under conditions promoting reductive dechlorination

Frontiers in Microbiology, 2016
The toxicity of polychlorinated biphenyls (PCB) can be efficiently reduced in contaminated marine sediments through the reductive dechlorination process lead by anaerobic organohalide bacteria.

Metagenomic- and Cultivation-Based Exploration of Anaerobic Chloroform Biotransformation in Hypersaline Sediments as Natural Source of Chloromethanes

Microorganisms, 2020
Chloroform (CF) is an environmental contaminant that can be naturally formed in various environments ranging from forest soils to salt lakes. Here we investigated CF removal potential in sediments obtained from hypersaline lakes in Western Australia ...

Multi-method assessment of the intrinsic biodegradation potential of an aquifer contaminated with chlorinated ethenes at an industrial area in Barcelona (Spain) [PDF]

, 2020
The bioremediation potential of an aquifer contaminated with tetrachloroethene (PCE) was assessed by combining hydrogeochemical data of the site, microcosm studies, metabolites concentrations, compound specific-stable carbon isotope analysis and the ...

Vitamin B12 as a source of variability in isotope effects for chloroform biotransformation by Dehalobacter

MicrobiologyOpen, Volume 13, Issue 4, August 2024.
The presence of vitamin B12 has a significant effect on carbon isotope effects, consistent with an isotope masking effect. We interpret this in the context of predicted enzyme structures. Abstract Carbon and chlorine isotope effects for biotransformation of chloroform by different microbes show significant variability.

Integrative isotopic and molecular approach for the diagnosis and implementation of an efficient in-situ enhanced biological reductive dechlorination of chlorinated ethenes [PDF]

, 2020
Based on the previously observed intrinsic bioremediation potential of a site originally contaminated with perchloroethene (PCE), field-derived lactate-amended microcosms were performed to test different lactate isomers and concentrations, and find ...

Functional Expression and Characterization of Tetrachloroethene Dehalogenase From Geobacter sp.

Frontiers in Microbiology, 2018
Reductive dehalogenase (RDase) consists of two parts, RdhA and RdhB. RdhA is the catalytic subunit, harboring a cobalamin cofactor and two Fe–S clusters. RdhA is anchored to the cytoplasmic membrane via the membrane anchoring subunit, RdhB.
