Environmental Microbiology, Volume 28, Issue 3, March 2026.Two novel thermophilic bacteria, Thermincola strain AZ34E and Carboxydocella strain AZ29I, were isolated from hydrothermal environments and shown to oxidise carbon monoxide via the water‐gas shift reaction. Comparative genomic and phylogenetic analyses revealed that all currently described isolates within Thermincola and Carboxydocella each represent a

Cobamide Fingerprinting Reveals Nutritional Diversity of Vitamin B12 in Edible Shellfish
FishesIn edible shellfish, vitamin B12 content has traditionally been evaluated based on total content; however, recent studies reveal substantial diversity in corrinoid composition among species. This review integrates molecular and ecological perspectives to

Molecular Reproduction and Development, Volume 93, Issue 2, February 2026.ABSTRACT Epidemiological data from assisted reproductive technologies (ART) link vitamin B12 (VitB12) deficiency to shorter gestation, low birth weight, and reduced live birth rates. VitB12 also plays a critical role in fertility for both sexes by supporting gamete quality.

, 2017 We investigate the correlations between the redox potentials of nonalkylated cobalt corrinoids and the Co–C bond dissociation energies (BDEs) of the methylated species with an aqua or histidine axial ligand. A set of cobalt corrinoids, cobalamin, and its

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.This work presents the physiological exploration of the halo‐alkaliphilic, carboxydotrophic acetogen bacterium MD4. In contrast to well‐characterised neutrophilic and slightly acidophilic acetogenic carboxydotrophs, this work shows an important role for formate production, instead of ethanol, as a redox exhaust mechanism in alkaline conditions ...

A Cytochrome c‐Containing Periplasmic Nitrate Reductase in the Acetogen Sporomusa ovata
Environmental Microbiology, Volume 28, Issue 1, January 2026.Sporomusa ovata, a cytochrome‐containing, acetogenic bacterium, conserves energy by reduction of carbon dioxide to acetate. Nitrate serves as additional electron acceptor and is reduced to ammonium, resulting in increased growth and reduced acetate production.
