The role of acetogens in microbially influenced corrosion of steel [PDF]
Frontiers in Microbiology, 2014 Microbially influenced corrosion (MIC) of iron (Fe(0)) by sulfate-reducing bacteria (SRB) has been studied extensively. Through a mechanism, that is still poorly understood, electrons or hydrogen (H2) molecules are removed from the metal surface and used as electron donor for sulfate reduction.

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Mixed‐culture fermentation generally produces volatile fatty acids (VFAs) as a mixture of C2–C6 acids. Among operational parameters, temperature has a distinct effect on the microorganisms' metabolic activity, which can shift the composition of the metabolites.

Biotechnology and Bioengineering, EarlyView.With a thermotolerant C. necator mutant the SCP production costs can be decreased by $0.98/kg. ABSTRACT Autotrophic CO2 conversion to Single Cell Protein (SCP) using H2 and O2 is gaining commercial traction for food and feed production. Cupriavidus necator H16 is a key chassis organism for this “knallgas” fermentation, but industrial operation is ...

The Role of Oxidative Stress in Periodontitis
Journal of Periodontal Research, EarlyView.Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

A Third Way of Energy Conservation in Acetogenic Bacteria
Microbiology Spectrum, 2022 Acetogenic bacteria grow by making acetate from CO 2 and are considered the first life forms on Earth since they couple CO 2 reduction to the conservation of energy. How this is achieved has been an enigma ever since.
