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.

Understanding the sources, function, and irreplaceable role of cobamides in organohalide-respiring bacteria

Frontiers in Microbiology
Halogenated organic compounds are persistent pollutants that pose a serious threat to human health and the safety of ecosystems. Cobamides are essential cofactors for reductive dehalogenases (RDase) in organohalide-respiring bacteria (OHRB), which ...

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 ...

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.

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 ...

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
