Comparative Physiology and Genomics of Thermincola and Carboxydocella Strains and Description of Two Novel Isolates

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

Microbes display broad diversity in cobamide preferences

mSystems
Cobamides, the vitamin B12 (cobalamin) family of cofactors, are used by most organisms but produced by only a fraction of prokaryotes, and are thus considered key shared nutrients among microbes.

Adaptation of the autotrophic acetogen Sporomusa ovata to methanol accelerates the conversion of CO₂ to organic products [PDF]

, 2015
Acetogens are efficient microbial catalysts for bioprocesses converting C1 compounds into organic products. Here, an adaptive laboratory evolution approach was implemented to adapt Sporomusa ovata for faster autotrophic metabolism and CO(2) conversion to

Geochemical and microbial community determinants of reductive dechlorination at a site biostimulated with glycerol [PDF]

, 2016
Biostimulation is widely used to enhance reductive dechlorination of chlorinated ethenes in contaminated aquifers. However, the knowledge on corresponding biogeochemical responses is limited. In this study glycerol was injected in an aquifer contaminated

Carboxydotrophic Acetogenesis in Alkaline Conditions Results in Transient Formate Production by the Halo‐Alkaliphilic Acetogen Haloacetibacter carboxydivorans Gen. Nov. sp. Nov

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 bacterial chloroform reductive dehalogenase: purification and biochemical characterization

Microbial Biotechnology, 2017
Summary We report herein the purification of a chloroform (CF)‐reducing enzyme, TmrA, from the membrane fraction of a strict anaerobe Dehalobacter sp. strain UNSWDHB to apparent homogeneity with an approximate 23‐fold increase in relative purity compared

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.

Navigating Transition Metal‐Dependent Cell Death: Mechanisms, Crosstalk, and Future Directions

Advanced Science, Volume 12, Issue 46, December 11, 2025.
Transition metals trigger distinct regulated cell death pathways beyond traditional apoptosis. This review examines ferroptosis (iron‐catalyzed lipid peroxidation) and cuproptosis (copper‐induced mitochondrial proteotoxicity), while exploring hypothetical “cobaltosis” as a novel pathway.

Control of Metal-Catalyzed Reactions by Organic Ligands: From Corrinoid and Porphinoid Metal Complexes to Tailor-Made Catalysts for Asymmetric Synthesis

CHIMIA, 2006
Corrinoid and porphinoid metal complexes playa fundamental role in nature as catalysts for a variety of biochemical transformations. The properties of the metal ion in these complexes are strongly influenced by the macrocyclic ligand.
