Exploring the Potential of Corynebacterium glutamicum to Produce the Compatible Solute Mannosylglycerate

Frontiers in Bioengineering and Biotechnology, 2021
The compatible solute mannosylglycerate (MG) has exceptional properties in terms of protein stabilization and protection under salt, heat, and freeze-drying stresses as well as against protein aggregation. Due to these characteristics, MG possesses large

Microbial Community Changes in a Chlorinated Solvents Polluted Aquifer Over the Field Scale Treatment With Poly-3-Hydroxybutyrate as Amendment

Frontiers in Microbiology, 2018
This study investigated the organohalide-respiring bacteria (OHRB) and the supporting microbial populations operating in a pilot scale plant employing poly-3-hydroxybutyrate (PHB), a biodegradable polymer produced by bacteria from waste streams, for the ...

Diversity of dehalorespiring bacteria and selective enrichment of aryl halides-dechlorinating consortium from sedimentary environment near an oil refinery

Journal of Taibah University for Science, 2018
This study demonstrated the potential for reductive dechlorination of aryl halides in a sedimentary environment by naturally occurring bacteria. A laboratory sediment microcosm and highly enriched, stable dechlorinating cultures were established using ...

Incomplete Wood-Ljungdahl pathway facilitates one-carbon metabolism in organohalide-respiring Dehalococcoides mccartyi. [PDF]

Proc Natl Acad Sci U S A, 2014
Significance We have studied the functionality of an incomplete acetyl-CoA “Wood–Ljungdahl” pathway in a strictly organohalide-respiring bacterium, Dehalococcoides mccartyi . We found that in addition to its ability to incorporate exogenous formate, this pathway cleaves acetyl-CoA to generate methyl ...

Effect of Social Rank on Gut Microbes and Their Metabolites of Greater Long‐Tailed Hamsters (Tscherskia triton)

Integrative Zoology, EarlyView.
Social rank in greater long‐tailed hamsters (Tscherskia triton) shapes gut microbiota composition and metabolite profiles. Dominant males exhibit a “high‐vigilance, metabolically activated” phenotype, with elevated aggression and specific gut microbiota enriched in energy‐harvesting taxa and fecal queuine.

From Energy Deprivation Stress to Catalytic Adaptation of Reductive Dehalogenase TmrA for 1,1‐DCA Dechlorination: An Experimental and in Silico Study

Microbial Biotechnology, Volume 19, Issue 4, April 2026.
Adaptive evolution of Dehalobacter restrictus strain UNSWDHB under a ratio of 1:9 chloroform:1,1‐DCA regime increased 1,1‐DCA dechlorination. Sequencing and molecular dynamics simulation reveal high‐entropy tmrA mutations that improved 1,1‐DCA binding energy and stabilize the catalytic pocket, outlining a route to tune reductive dehalogenases for ...

Field Test of a Bioelectrochemical Membrane‐Less Reactor for Chlorinated Aliphatic Hydrocarbon and Nitrate Removal from a Contaminated Groundwater

ChemPlusChem, Volume 90, Issue 8, August 2025.
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 ...

Thermochemical Recycling and Degradation Strategies of Halogenated Polymers (F−, Cl−, Br−): A Holistic Review Coupled with Mechanistic Insights

The Chemical Record, Volume 25, Issue 6, June 2025.
This review aims to comprehensively address recent degradation techniques (physical, chemical and biological) of halogenated waste polymers with a prime focus on thermal degradation techniques. Exploiting various metal oxides during co‐pyrolysis is deemed a viable solution for recycling halogenated polymeric waste.

The iron–sulfur‐containing HypC‐HypD scaffold complex of the [NiFe]‐hydrogenase maturation machinery is an ATPase

FEBS Open Bio, Volume 9, Issue 12, Page 2072-2079, December 2019., 2019
The iron–sulfur protein HypD and the small HypC chaperone form the core of the [NiFe]‐hydrogenase maturation machinery. We report here that both proteins have intrinsic ATP‐hydrolyzing activity and that this activity is synergistically enhanced in the HypD‐HypC complex.
