Genomic Survey of Carbon Monoxide Dehydrogenases Reveals Their Widespread Distribution in Marine Habitats

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Protein sequence surveys show that nickel‐ and molybdenum/copper‐containing carbon monoxide dehydrogenases (CODHs) are widespread in the ocean. Phylogenetic and genome context analyses reveal that marine CODHs are highly diverse in both evolutionary history and functional organisation.

Genomic and enzymatic evidence for acetogenesis among multiple lineages of the archaeal phylum Bathyarchaeota widespread in marine sediments

open access: yes, 2016
Members of the archaeal phylum Bathyarchaeota are widespread and abundant in the energy-deficient marine subsurface sediments. However, their life strategies have remained largely elusive.

Optimizing Microbial Fuel Cell Efficiency Through a Designed Electrogenic Consortium to Remove Alkylbenzenes

open access: yesChemElectroChem, Volume 13, Issue 10, 19 May 2026.
A mangrove‐derived electrogenic microbial consortium was successfully acclimated to codegrade ethylbenzene and xylenes in a microbial fuel cell (MFC). Acclimation provided high degradation efficiencies (up to 97%) and improved energy recovery. The MFC reached voltage of 520 mV and power density of 63.4 mW m−2.

Nanobiocatalysts: Potential Applications in Biofuel Production and Biotransformation

open access: yesCarbon Neutralization, Volume 5, Issue 3, May 2026.
The application of nanobiocatalysts in the field of biofuel production and the biotransformation of substrate were reviewed. Further, the possible research gaps in the field of biofuel and value‐added compound production and a possible way to enhance the application of nanobiocatalyst in future development are highlighted.

Methane emissions from fresh dairy cattle and pig slurry

open access: yesJournal of Environmental Quality, Volume 55, Issue 3, May/June 2026.
Abstract During manure storage, methane (CH4) is produced by anaerobic decomposition of organic matter by methanogens. Frequent removal and further processing of manure from the barn can reduce CH4 emissions. However, little is known about how much CH4 is lost during the adaptation of methanogens to the changing environment from the gut to storage. The

Acetogenic Methane‐Carbon Monoxide Comproportionation: An Exergonic but Unobserved Microbial Metabolism

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Microbial metabolism relies on redox reactions that exploit chemical disequilibria. While aerobic carbon oxidation, carbon fixation, and fermentation are well studied, the broader space of anaerobic carbon redox reactions remains underexplored.

Genome-scale analysis of Acetobacterium bakii reveals the cold adaptation of psychrotolerant acetogens by post-transcriptional regulation

open access: yes, 2018
Acetogens synthesize acetyl-CoA via CO2 or CO fixation, producing organic compounds. Despite their ecological and industrial importance, their transcriptional and post-transcriptional regulation has not been systematically studied. With completion of the

Genomic and in-situ Transcriptomic Characterization of the Candidate Phylum NPL-UPL2 From Highly Alkaline Highly Reducing Serpentinized Groundwater

open access: yesFrontiers in Microbiology, 2018
Serpentinization is a process whereby water interacts with reduced mantle rock called peridotite to produce a new suite of minerals (e.g., serpentine), a highly alkaline fluid, and hydrogen. In previous reports, we identified abundance of microbes of the

qPCR results of semi-continuous anaerobic digestion with and without vacuum stripping of digestate

open access: yes, 2021
To avoid inhibition of ammonia on acetogenesis and methanogenesis, a small portion of in-reactor digestate can be replaced daily by vacuum stripped digestate. Vacuum stripping of ammonia may also increase methane generation.

Mediative mechanism of bicarbonate on anaerobic propionate degradation revealed by microbial community and thermodynamics

open access: yes, 2018
Syntrophic acetogenesis of volatile fatty acids (VFAs) such as propionate and butyrate is considered as the rate-limiting step of anaerobic digestion.
