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.

Model-driven approach for the production of butyrate from CO2/H2 by a novel co-culture of C. autoethanogenum and C. beijerinckii

Frontiers in Microbiology, 2022
One-carbon (C1) compounds are promising feedstocks for the sustainable production of commodity chemicals. CO2 is a particularly advantageous C1-feedstock since it is an unwanted industrial off-gas that can be converted into valuable products while ...

A Metagenome‐Assembled Genome Catalog From the Global Ruminant Microbiomes

Animal Research and One Health, EarlyView.
The Ruminant Gastrointestinal MAG Catalog (RGMC) is a comprehensive global resource offering 40,812 strain‐level genomes across 53 bacterial and 4 archaeal classes. It greatly surpasses prior efforts in scale and diversity, serving as an essential foundation for research in ruminant nutrition, microbial function, and methane mitigation.

Acidogenic fermentation of pretreated food waste under psychrophilic conditions for volatile fatty acids production

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.

Insights into the Genome of the Anaerobic Acetogen Sporomusa silvacetica DSM 10669

, 2017
Sporomusa silvacetica is a spore-forming, anaerobic acetogen isolated from soil derived from east central Germany. The genome contains genes of the Wood-Ljungdahl pathway required for carbon fixation and genes involved in the biosynthesis of ...

Reducing Cooling Costs for Sustainable Food Biomanufacturing With Thermotolerant Cupriavidus necator H16 Mutant

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 ...

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.

Methanogen Colonisation Does Not Significantly Alter Acetogen Diversity in Lambs Isolated 17 h After Birth and Raised Aseptically

, 2012
Reductive acetogenesis is not competitive with methanogenesis in adult ruminants, whereas acetogenic bacteria are the dominant hydrogenotrophs in the early rumen microbiota.

Investigation of a new acetogen isolated from an enrichment of the tammar wallaby forestomach [PDF]

, 2014
Background: Forestomach fermentation in Australian marsupials such as wallabies and kangaroos, though analogous to rumen fermentation, results in lower methane emissions. Insights into hydrogenotrophy in these systems could help in devising strategies to

Moorella thermoacetica: A promising cytochrome- and quinone-containing acetogenic bacterium as platform for a CO2-based bioeconomy

Green Carbon, 2023
The negative effect of fossil-based industrial processes on the environment, especially the contribution to global warming by emitting greenhouse gases such as CO2 causes a global threat to mankind. Therefore, technologies are demanded by the society for
