CO₂fixation in acetogenic bacteria: Variations on a theme [PDF]

FEMS Microbiology Letters, 1986
An increasing number of strict anaerobic bacteria are being found which use an alternative pathway to the ubiquitous Calvin cycle for CO2 fixation into cell compounds and the ubiquitous Krebs cycle for acetyl CoA oxidation to CO2. The principles of this non-cyclic pathway, the acetyl CoA pathway, have long been studied in acetogenic bacteria.

Attenuated Strains of Pseudomonas aeruginosa: A Promising Cell Factory for Rhamnolipid Production

Microbial Biotechnology, Volume 18, Issue 11, November 2025.
PGN strains are generated by the deletion of virulence factor genes. The metabolic pathways and regulatory frameworks that lead to high‐efficiency production of rhamnolipids in P. aeruginosa are preserved in these strains. Therefore, PGN strains are promising bio‐safe cell factories for the industrial production of rhamnolipids.

Enrichment of syngas-converting communities from a multi-orifice baffled bioreactor [PDF]

, 2017
The substitution of natural gas by renewable biomethane is an interesting option to reduce global carbon footprint. Syngas fermentation has potential in this context, as a diverse range of low-biodegradable materials that can be used.

Current understanding of electroautotrophy and its relevance in astrobiology‐related research

mLife, Volume 4, Issue 5, Page 473-493, October 2025.
Abstract Electroautotrophy—the use of extracellular electrons as the primary energy source for autotrophic metabolism—remains understudied compared to photoautotrophy and chemoautotrophy. Its occurrence in deep‐earth and deep‐sea environments suggests profound implications for astrobiology, yet electroautotrophic microorganisms remain poorly explored ...

Sulfate-Reducing ElectroAutotrophs and Their Applications in Bioelectrochemical Systems

Frontiers in Energy Research, 2018
Electroautotrophs are microbes able to perform different biocathodic reactions by using CO2 as sole carbon source and electrochemical reducing power as a sole energy source.

Fecal Metaproteomics as a Tool to Monitor Functional Modifications Induced in the Gut Microbiota by Ketogenic Diet: A Case Study

PROTEOMICS, Volume 25, Issue 17-18, Page 62-69, September 2025.
ABSTRACT Metaproteomics is a valuable approach to characterize the biological functions involved in the gut microbiota (GM) response to dietary interventions. Ketogenic diets (KDs) are very effective in controlling seizure severity and frequency in drug‐resistant epilepsy (DRE) and in the weight loss management in obese/overweight individuals.

Converge or Diverge? Exploring the Fate of Taxonomically Different Anaerobic Digestion Communities Under Uniform Growth Conditions

Microbial Biotechnology, Volume 18, Issue 9, September 2025.
Three semi‐continuous enrichments, inoculated with distinctly different microbial communities, were run for 3 HRTs using a defined nutrient medium supporting all anaerobic digestion steps. 16S and metagenomic analyses showed final community structures were driven primarily by the initial inoculum, while the substrate had no deterministic effect ...
