Anaerobic Carbon Monoxide Dehydrogenase Diversity in the Homoacetogenic Hindgut Microbial Communities of Lower Termites and the Wood Roach [PDF]

open access: yes, 2011
Anaerobic carbon monoxide dehydrogenase (CODH) is a key enzyme in the Wood-Ljungdahl (acetyl-CoA) pathway for acetogenesis performed by homoacetogenic bacteria.

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

open access: yesEnvironmental 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

A Multi‐Organ Atlas Links Gut Microbial Metabolites to Systemic Redox Changes in Aging Mice

open access: yesAging Cell, Volume 25, Issue 3, March 2026.
A gut‐derived metabolic signature drives systemic aging phenotypes. Integrated multi‐omics profiling of young versus aged mice identifies a conserved aging signature characterized by the depletion of protective lysophosphatidylcholines (LPC 22:0) and the concurrent accumulation of pro‐oxidative microbial catabolites (TMAO, IAA).

Physiological Evidence for Isopotential Tunneling in the Electron Transport Chain of Methane-Producing Archaea [PDF]

open access: yes, 2017
Many, but not all, organisms use quinones to conserve energy in their electron transport chains. Fermentative bacteria and methane-producing archaea (methanogens) do not produce quinones but have devised other ways to generate ATP. Methanophenazine (MPh)

Contrasted Reactivity to Oxygen Tensions in Frankia sp. Strain CcI3 throughout Nitrogen Fixation and Assimilation [PDF]

open access: yes, 2014
Reconciling the irreconcilable is a primary struggle in aerobic nitrogen-fixing bacteria. Although nitrogenase is oxygen and reactive oxygen species-labile, oxygen tension is required to sustain respiration.

Complex Multimeric [FeFe] Hydrogenases: Biochemistry, Physiology and New Opportunities for the Hydrogen Economy

open access: yesFrontiers in Microbiology, 2018
Hydrogenases are key enzymes of the energy metabolism of many microorganisms. Especially in anoxic habitats where molecular hydrogen (H2) is an important intermediate, these enzymes are used to expel excess reducing power by reducing protons or they are ...

In vitro activation of [FeFe] hydrogenase: new insights into hydrogenase maturation

open access: yesJBIC Journal of Biological Inorganic Chemistry, 2007
The in vitro activation of the [FeFe] hydrogenase is accomplished by combining Escherichia coli cell extracts containing the heterologously expressed inactive HydA with extracts in which hydrogenase-specific maturation proteins HydE, HydF, and HydG are expressed in concert. Interestingly, the process of HydA activation occurs rapidly and in the absence
