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 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.

Roles of acetogens and methanogens in carbon capture and storage
, 2013 Carbon capture and storage (CCS) aims to reduce atmospheric CO2 by capturing emitted gas for storage in subsurface locations. Microorganisms such as methanogens and acetogens, can utilize H2 and CO2 as a carbon and energy source in the subsurface.

Baltic Sea methanogens compete with acetogens for electrons from metallic iron [PDF]
, 2019 Microbially induced corrosion of metallic iron (Fe0)-containing structures is an environmental and economic hazard. Methanogens are abundant in low-sulfide environments and yet their specific role in Fe0 corrosion is poorly understood.

Obligate autotrophy at the thermodynamic limit of life in a new acetogenic bacterium
Frontiers in Microbiology, 2023 One of the important current issues of bioenergetics is the establishment of the thermodynamic limits of life. There is still no final understanding of what is the minimum value of the energy yield of a reaction that is sufficient to be used by an ...

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.

Interconnection of methanogenic and acetogenic pathways [PDF]
FEMS Microbiology Letters, 1983 Methanopterin displays a folate-like biochemistry: methenyl-, methylene- and methyltetrahydromethanopterin are intermediates in the process of methanogenesis. A corrinoid-enzyme is involved in methanol conversion and the possible function of such enzymes in cell-carbon synthesis and acetate conversion is discussed.
