Acetogenesis does not replace ketogenesis in fasting piglets infused with hexanoate

open access: yesAmerican Journal of Physiology-Endocrinology and Metabolism, 1998
The current studies were performed to better understand the physiological relevance of acetate in the poorly ketogenic piglet and to determine if endogenous acetogenesis rises with increased mitochondrial fatty acid β-oxidation, analogous to ketogenesis.

Mitigating methane emissions and promoting acetogenesis in ruminant livestock

open access: yesFrontiers in Animal Science
Through enteric fermentation, ruminants convert fibrous biomass into high-quality proteins like meat and milk. In this process however, methanogenic archaea in the ruminant gastrointestinal tract produce methane, a potent greenhouse gas, from the by ...

Limits to dihydrogen incorporation into electron sinks alternative to methanogenesis in ruminal fermentation [PDF]

open access: yesFrontiers in Microbiology, 2015
Research is being conducted with the objective of decreasing methane (CH4) production in the rumen, as methane emissions from ruminants are environmentally damaging and a loss of digestible energy to ruminants. Inhibiting ruminal methanogenesis generally

Bioaugmentation in anaerobic digesters: a systematic review [PDF]

open access: yesBiotechnology for Biofuels and Bioproducts
Bioaugmentation, the intentional introduction of specific microorganisms into anaerobic digestion (AD) systems, has shown promise in enhancing methane production and in mitigating stressful conditions, particularly in systems operating below optimal ...

A Third Way of Energy Conservation in Acetogenic Bacteria

open access: yesMicrobiology Spectrum, 2022
Acetogenic bacteria are a group of strictly anaerobic bacteria that make a living from acetate formation from two molecules of CO2 via the Wood-Ljungdahl pathway (WLP).

Anaerobic digestion of donkey dung for biogas production

open access: yesSouth African Journal of Science, 2016
Biogas can provide a solution to some of South Africa’s energy needs, especially in rural areas of Eastern Cape Province that have plentiful biogas substrates from donkeys, goats, sheep, cattle and chicken.

Extracellular Electron Uptake by Acetogenic Bacteria: Does H2 Consumption Favor the H2 Evolution Reaction on a Cathode or Metallic Iron?

open access: yesFrontiers in Microbiology, 2020
Some acetogenic bacteria are capable of using solid electron donors, such as a cathode or metallic iron [Fe(0)]. Acetogens using a cathode as electron donor are of interest for novel applications such as microbial electrosynthesis, while microorganisms ...

Selected issues of anaerobic digestion based on the studies on hydrogen- and methane yielding bioreactors [PDF]

open access: yes, 2019
Anaerobic digestion of organic matter results from the metabolic activity of many groups of microorganisms. Interactions between microorganisms during acidogenesis, acetogenesis and methanogenesis, source of inoculum, type of feedstock and operational ...

The root zone of graminoids: A niche for H2-consuming acetogens in a minerotrophic peatland

open access: yesFrontiers in Microbiology, 2022
The importance of acetogens for H2 turnover and overall anaerobic degradation in peatlands remains elusive. In the well-studied minerotrophic peatland fen Schlöppnerbrunnen, H2-consuming acetogens are conceptualized to be largely outcompeted by iron ...

Dichloromethane utilized by an anaerobic mixed culture: acetogenesis and methanogenesis [PDF]

open access: yesBiodegradation, 1991
Dichloromethane (8.9 mg/l) was eliminated from industrially polluted, anaerobic groundwater in a fixed-bed reactor (43 m3) which was packed with activated charcoal and operated continuously for over three years. The elimination of dichloromethane over this period was some ten-fold in excess of the sorptive capacity of the charcoal, and the elimination (
