Chemoorganoautotrophic lifestyle of the anaerobic enrichment culture N47 growing on naphthalene

Communications Biology
In almost all respiratory organisms, organic substrates are degraded via catabolic processes to the central metabolite acetyl-CoA which is then oxidized to CO2 for energy metabolism or used as a building block for anabolism.

Anaerobic Biohydrogenation of Isoprene by Acetobacterium wieringae Strain Y

mBio, 2022
Isoprene is a ubiquitously distributed, biogenic, and climate-active organic compound. Microbial isoprene degradation in oxic environments is fairly well understood; however, studies exploring anaerobic isoprene metabolism remain scarce, with no isolates

Unravelling the Chemolithoautotrophic Metabolism of the Carboxydotrophic Knallgas Bacterium Hydrogenophaga pseudoflava

Microbial Biotechnology, Volume 19, Issue 11, November 2026.
Proteomics of the aerobic carboxydotroph Hydrogenophaga pseudoflava across trophic conditions revealed that an unphysiological CO concentration causes a redox imbalance and stress response. CO dehydrogenase I and the membrane‐bound hydrogenase were essential for CO and H2 oxidation, respectively, whereas the soluble hydrogenase likely supports redox ...

Enzymatic Electrosynthesis for Sustainable CO2 Conversion: Advancing Circular Carbon Economy

Carbon Energy, Volume 8, Issue 10, October 2026.
Enzymatic electrosynthesis (EES) offers molecular precision in synthesizing value‐added products from CO2. We highlight its distinct edge over alternative enzyme‐hybrid systems and analyze electron transfer pathways. Key strategies to overcome electron transfer bottlenecks and expand product diversity are addressed, and also data‐driven approaches for ...

Short‐Chain Fatty Acids: Microbial Metabolites Driving Gut‐Eye Axis Signaling

Comprehensive Physiology, Volume 16, Issue 5, October 2026.
Short‐chain fatty acids generated by gut microbial fermentation link diet to ocular physiology via the gut–eye axis. Through systemic distribution, these metabolites regulate GPCR signaling, epigenetic pathways, inflammation, and angiogenesis, shaping retinal homeostasis and highlighting therapeutic potential in ocular vascular and inflammatory ...

A Review on Carbon Sequestration Techniques From Geological to Biological Methods: Mechanisms, Methods, and Future Perspectives

Engineering Reports, Volume 8, Issue 10, October 2026.
This study reviews CO2 storage methods: geological (depleted reservoirs, saline aquifers, salt caverns, basalt), oceanic (dissolution, hydrates, phytoplankton), and biological (microalgae like Chlorella and Spirulina with 10–50× higher capture than plants; MICP by Sporosarcina pasteurii).

Homoacetogenic Conversion of Mannitol by the Thermophilic Acetogenic Bacterium Thermoanaerobacter kivui Requires External CO2

Frontiers in Microbiology, 2020
Acetogenic microorganisms utilize organic substrates such as sugars in addition to hydrogen (H2) + carbon dioxide (CO2). Recently, we reported that the thermophilic acetogenic microorganism Thermoanaerobacter kivui is among the few acetogens that utilize

Electroactive Microbiomes: Electron Transfer Mechanisms and Environmental Biotechnology Applications

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Electroactive microbiomes couple direct, mediated, conductive, and interspecies electron transfer with biofilm organisation to drive wastewater treatment, bioremediation, resource recovery, carbon conversion, and biosensing. Their performance depends on balancing electron transfer, mass transport, community structure, and electrode–biofilm interactions
