Attempted induction of reductive acetogenesis into the rumen fermentation in vitro [PDF]

Reproduction Nutrition Development, 1996
Rumen and caecal contents, obtained from slaughterhouse cattle and rumen contents obtained from a fistulated wether were incubated in vitro with ground hay in the presence and absence of, respectively, casein hydrolysate and mucin. Differences in stoichiometry of rumen and caecal fermentations, indicative of reductive acetogenesis in the caecum, were ...

Promotion of methane production by magnetite via increasing acetogenesis revealed by metagenome-assembled genomes

, 2022
Metal oxides are wildly studied to enhance anaerobic digestion and the methanogenic process, which is generally interpreted by increased direct interspecies electron transfer (DIET). Yet microbial mechanisms involved are under debate.

Single-Cell Genomics Reveals a Diverse Metabolic Potential of Uncultivated Desulfatiglans-Related Deltaproteobacteria Widely Distributed in Marine Sediment

Frontiers in Microbiology, 2018
Desulfatiglans-related organisms comprise one of the most abundant deltaproteobacterial lineages in marine sediments where they occur throughout the sediment column in a gradient of increasing sulfate and organic carbon limitation with depth ...

Does acetogenesis really require especially low reduction potential?

, 2013
Acetogenesis is one of the oldest metabolic processes on Earth, and still has a major global significance. In this process, acetate is produced via the reduction and condensation of two carbon dioxide molecules. It has long been assumed that acetogenesis

Enrichment of homoacetogens converting H2/CO2 into acids and ethanol and simultaneous methane production

Engineering in Life Sciences, 2023
An anaerobic granular sludge was enriched to utilize H2/CO2 in a continuous gas‐fed up‐flow anaerobic sludge reactor by applying operating conditions expected to produce acetic acid, butyric acid, and ethanol.

Homo-Acetogens: Their Metabolism and Competitive Relationship with Hydrogenotrophic Methanogens

Microorganisms, 2022
Homo-acetogens are microbes that have the ability to grow on gaseous substrates such as H2/CO2/CO and produce acetic acid as the main product of their metabolism through a metabolic process called reductive acetogenesis.

Atypical one-carbon metabolism of an acetogenic and hydrogenogenic Moorella thermoacetica strain

, 2009
A thermophilic spore-forming bacterium (strain AMP) was isolated from a thermophilic methanogenic bioreactor that was fed with cobalt-deprived synthetic medium containing methanol as substrate.
