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

open access: yesFrontiers 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

open access: yesMicrobial 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

open access: yesGeobiology, 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.

Molecular insights intocobalamin-dependent enzyme systemsfrom organohalide-respiring bacteria [PDF]

open access: yes, 2013
The evolution of microorganisms over millions of years has led to an impressive adaptability regarding the utilisation of different environmental conditions. The identification of bacterial species with the fascinating features to use cobalamin-dependent metalloenzymes to (i) extract energy from halogenated organic compounds (organohalides) and (ii ...
