Sodium bioenergetics in methanogens and acetogens [PDF]

FEMS Microbiology Letters, 1990
Recent investigations with Methanosarcina barkeri elucidated the role of sodium ions in the energy metabolism of methanogenic bacteria and provided evidence for a novel mechanism of energy transduction with Na+ as the coupling ion. During methanogenesis from methanol, an eletrochemical sodium gradient generated by a Na+/H+ antiporter is used as the ...

Exploring Ectoine Production From Methanol, Formate, and Electrochemically Produced Formate by Methyloligella halotolerans

Engineering in Life Sciences, Volume 26, Issue 1, January 2026.
ABSTRACT Microbial synthesis using renewable C1‐carbon sources like electrochemically produced formate (e‐formate) represents a promising approach for climate‐neutral chemical production. This study investigates formate utilization for ectoine biosynthesis by the halophilic methylotroph Methyloligella halotolerans.

Clumped isotopes as fingerprints of microbial methane production pathways in marine sediments

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Microbial methanogenesis in marine sediments produces significant amounts of methane from various substrates; however, identifying the active pathways in situ remains challenging. While the bulk and clumped isotopic signatures of methane from different pathways have been studied in pure cultures, these are difficult to compare with complex ...

Homoacetogenesis and microbial community composition are shaped by pH and total sulfide concentration [PDF]

, 2019
Biological CO2 sequestration through acetogenesis with H-2 as electron donor is a promising technology to reduce greenhouse gas emissions. Today, a major issue is the presence of impurities such as hydrogen sulfide (H2S) in CO2 containing gases, as they ...

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.

Formate Is Required for Growth of the Thermophilic Acetogenic Bacterium Thermoanaerobacter kivui Lacking Hydrogen-Dependent Carbon Dioxide Reductase (HDCR)

Frontiers in Microbiology, 2020
The hydrogen-dependent carbon dioxide reductase is a soluble enzyme complex that directly utilizes hydrogen (H2) for the reduction of carbon dioxide (CO2) to formate in the first step of the acetyl-coenzyme A- or Wood-Ljungdahl pathway (WLP).

Solar-driven carbon dioxide fixation using photosynthetic semiconductor bio-hybrids. [PDF]

, 2019
Solar-driven conversion of carbon dioxide to value-added carbon products is an ambitious objective of ongoing research efforts. However, high overpotential, low selectivity and poor CO2 mass transfer plague purely inorganic electrocatalysts.
