Bioenhanced back diffusion and population dynamics of Dehalococcoides mccartyi strains in heterogeneous porous media

Chemosphere, 2020
Diffusion, sorption-desorption, and biodegradation influence chlorinated solvent storage in, and release (mass flux) from, low-permeability media. Although bioenhanced dissolution of non-aqueous phase liquids has been well-documented, less attention has been directed towards biologically-mediated enhanced diffusion from low-permeability media.

Microbiome signature and diversity regulates the level of energy production under anaerobic condition

Scientific Reports, 2021
The microbiome of the anaerobic digester (AD) regulates the level of energy production. To assess the microbiome diversity and composition in different stages of anaerobic digestion, we collected 16 samples from the AD of cow dung (CD) origin.

Versatility in corrinoid salvaging and remodeling pathways supports corrinoid-dependent metabolism in Dehalococcoides mccartyi. [PDF]

Appl Environ Microbiol, 2012
ABSTRACTCorrinoids are cobalt-containing molecules that function as enzyme cofactors in a wide variety of organisms but are produced solely by a subset of prokaryotes. Specific corrinoids are identified by the structure of their axial ligands. The lower axial ligand of a corrinoid can be a benzimidazole, purine, or phenolic compound. Though it is known

BEAN and HABAS: Polyphyletic insertions in the DNA‐directed RNA polymerase

Protein Science, Volume 33, Issue 11, November 2024.
Abstract The β and β′ subunits of the RNA polymerase (RNAP) are large proteins with complex multi‐domain architectures that include several insertional domains. Here, we analyze the domain organizations of RNAP‐β and RNAP‐β′ using sequence, experimentally determined structures and AlphaFold structure predictions.

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 ...

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 ...

Completely dechlorinating of trichloroethene by a Dehalococcoides mccartyi-containing microbial consortium in the absence of cobalamin

, 2021
Abstract Completely dechlorinating of trichloroethene (TCE) by Dehalococcoides mccartyi (D.mccartyi) is catalyzed by reductive dehalogenases (RDases) which possess cobalamin as the crucial cofactor, whereas virtually all pure D.mccartyi strains isolated thus far are corrinoid auxotrophs.
