Biomarkers’ Responses to Reductive Dechlorination Rates and Oxygen Stress in Bioaugmentation Culture KB-1TM

Microorganisms, 2018
Using mRNA transcript levels for key functional enzymes as proxies for the organohalide respiration (OHR) rate, is a promising approach for monitoring bioremediation populations in situ at chlorinated solvent-contaminated field sites.

Genome‐resolved metagenomics revealed novel microbial taxa with ancient metabolism from macroscopic microbial mat structures inhabiting anoxic deep reefs of a Maldivian Blue Hole

Environmental Microbiology Reports, Volume 16, Issue 5, October 2024.
This study investigates macroscopic microbial mat structures found in complete anoxic conditions at 70 m depth in a Maldivian Blue Hole. Genome‐resolved metagenomic led to the description of several new taxa with ancient metabolism revealing novel bacterial genera belonging to the order Dehalococcoidales as dominant members of these communities ...

Metabolic versatility of aerobic methane‐oxidizing bacteria under anoxia in aquatic ecosystems

Environmental Microbiology Reports, Volume 16, Issue 5, October 2024.
Besides conventional aerobic oxidation pathway, MOB has four underlying metabolic strategies under anoxia: (i) forming a consortium with oxygenic microorganisms; (ii) self‐generation/storage of O2 by MOB; (iii) forming a consortium with non‐oxygenic heterotrophic bacteria that use other electron acceptors; (iv) and utilizing alternative electron ...

Sister Dehalobacter Genomes Reveal Specialization in Organohalide Respiration and Recent Strain Differentiation Likely Driven by Chlorinated Substrates

Frontiers in Microbiology, 2016
The genomes of two closely related Dehalobacter strains (strain CF and strain DCA) were assembled from the metagenome of an anaerobic enrichment culture that reductively dechlorinates chloroform (CF), 1,1,1-trichloroethane (1,1,1-TCA) and 1,1 ...

Burning question: Rethinking organohalide degradation strategy for bioremediation applications

Microbial Biotechnology, Volume 17, Issue 8, August 2024.
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 ...

Biodegradation of chloroethene compounds under microoxic conditions

Biotechnology and Bioengineering, Volume 121, Issue 3, Page 1036-1049, March 2024.
The authors examined the biodegradation of chloroethene compounds under microoxic conditions. The results indicated that partial reductive and cometabolic biodegradation of chloroethene compounds occurred concurrently. The findings of this study have significant implications for further research on chloroethene compound biodegradation, particularly in ...

Characterization and Adaptation of Anaerobic Sludge Microbial Communities Exposed to Tetrabromobisphenol A. [PDF]

PLoS ONE, 2016
The increasing occurrence of tetrabromobisphenol A (TBBPA) in the environment is raising questions about its potential ecological and human health impacts. TBBPA is microbially transformed under anaerobic conditions to bisphenol A (BPA).
