Occurrence of ferredoxin:NAD+ oxidoreductase activity and its ion specificity in several Gram-positive and Gram-negative bacteria [PDF]

PeerJ, 2016
A ferredoxin:NAD+ oxidoreductase was recently discovered as a redox-driven ion pump in the anaerobic, acetogenic bacterium Acetobacterium woodii. The enzyme is assumed to be encoded by the rnf genes.

Epigenetic Perspectives on Maternal Gut Microbiota's Impact on Embryonic and Fetal Development

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
This review summarizes how maternal health and nutrition shape gut microbiota via epigenetics to regulate embryonic development. It highlights microbiota‐embryo interactions, disruption by prenatal chemical exposures, and personalized nutrition for disease prevention, offering novel insights and therapeutic targets.

Microbial Electrosynthesis Reshapes Energy Metabolism and Physiology in Clostridium ljungdahlii

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
Microbial electrosynthesis drives Clostridium ljungdahlii into a distinct stress‐associated physiological state, different from gas fermentation. Comparative multi‐omics and electron microscopy reveal physiological constraints that help explain the poor performance of MES.

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

ChemElectroChem, 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.

Butyrate production in the acetogen Eubacterium limosum is dependent on the carbon and energy source

Microbial Biotechnology, 2021
Summary Eubacterium limosum KIST612 is one of the few acetogenic bacteria that has the genes encoding for butyrate synthesis from acetyl‐CoA, and indeed, E. limosum KIST612 is known to produce butyrate from CO but not from H2 + CO2.

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

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

Journal 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.

Emerging Technologies for Biobutanol Production via Syngas Fermentation

GCB Bioenergy, Volume 18, Issue 5, May 2026.
Biobutanol production from syngas is promising but limited by microbial energy conservation and gas–liquid mass transfer. This review integrates advances in cultivation control and bioreactor engineering with next‐generation biological tools including metabolic rewiring, co‐cultivation and chain elongation, and electro‐fermentation to enable carbon ...
