Primary to post‐depositional microbial controls on the stable and clumped isotope record of shoreline sediments at Fayetteville Green Lake

Geobiology, Volume 22, Issue 4, July/August 2024.
Abstract Lacustrine carbonates are a powerful archive of paleoenvironmental information but are susceptible to post‐depositional alteration. Microbial metabolisms can drive such alteration by changing carbonate saturation in situ, thereby driving dissolution or precipitation.

Microbial Autotrophy Recorded by Carbonate Dual Clumped Isotope Disequilibrium

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 6, June 2024.
Abstract The proliferation of microbial carbon fixation is a key control on the evolution of the biosphere and global carbon cycle. Most records of these metabolisms in ancient rocks come from organic matter or fossils, which are not always preserved.

Ecology and biogeography of bacterial communities associated with chloroethene-contaminated aquifers

Frontiers in Microbiology, 2012
Massive usage, along with careless handling, storage, spills and leakages made chloroethenes (CEs) one of the most abundant classes of groundwater contaminants.

Genome sequence of the organohalide-respiring Dehalogenimonas alkenigignens type strain (IP3-3(T)) [PDF]

, 2016
Dehalogenimonas alkenigignens IP3-3(T) is a strictly anaerobic, mesophilic, Gram negative staining bacterium that grows by organohalide respiration, coupling the oxidation of H-2 to the reductive dehalogenation of polychlorinated alkanes.

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 ...

Electrochemical applications in RAS: A review

Reviews in Aquaculture, Volume 16, Issue 1, Page 86-105, January 2024.
Abstract Electrochemical water treatment for recirculating aquaculture systems (RAS) is a promising approach for replacing the biological water treatment methods and establishing a new RAS generation with improved cost‐effectiveness, lower environmental footprint, and no start‐up periods. On top of ammonia oxidation directly into N2(g), electrochemical

Dechlorination and organohalide-respiring bacteria dynamics in sediment samples of the Yangtze Three Gorges Reservoir

Environmental Science and Pollution Research, 2013
Several groups of bacteria such as Dehalococcoides spp., Dehalobacter spp., Desulfomonile spp., Desulfuromonas spp., or Desulfitobacterium spp. are able to dehalogenate chlorinated pollutants such as chloroethenes, chlorobenzenes, or polychlorinated biphenyls under anaerobic conditions.

Functional genomics of corrinoid starvation in the organohalide-respiring bacterium Dehalobacter restrictus strain PER-K23

Frontiers in Microbiology, 2015
De novo corrinoid biosynthesis represents one of the most complicated metabolic pathways in nature. Organohalide-respiring bacteria (OHRB) have developed different strategies to deal with their need of corrinoid, as it is an essential cofactor of ...

Acetylene Fuels TCE Reductive Dechlorination by Defined Dehalococcoides/Pelobacter Consortia. [PDF]

, 2017
Acetylene (C2H2) can be generated in contaminated groundwater sites as a consequence of chemical degradation of trichloroethene (TCE) by in situ minerals, and C2H2 is known to inhibit bacterial dechlorination. In this study, we show that while high C2H2 (
