Methanol Metabolism in the Cytochrome and Menaquinone-Containing Acetogen Moorella thermoacetica. [PDF]

Environ Microbiol
The thermophilic acetogenic bacterium Moorella thermoacetica is a promising platform organism to convert C1 compounds to valuable products. Gaseous C1 substrates are technically difficult to use for fermentation in an industrial scale, but methanol, which can be produced chemically from carbon dioxide, is a suitable alternative.

Genomic and enzymatic evidence of acetogenesis by anaerobic methanotrophic archaea [PDF]

Nature Communications, 2020
Ocean cold seeps are poorly understood relative to related systems like hydrothermal vents. Here the authors use high pressure bioreactors and microbial communities from a cold seep mud volcano and find a previously missing step of methane conversion to ...

Reductive acetogenesis is a dominant process in the ruminant hindgut [PDF]

Microbiome
Background The microbes residing in ruminant gastrointestinal tracts play a crucial role in converting plant biomass to volatile fatty acids, which serve as the primary energy source for ruminants.

Biochemistry of methanol‐dependent acetogenesis in Eubacterium callanderi   KIST612 [PDF]

Environmental Microbiology, 2021
Summary Methanol is the simplest of all alcohols, is universally distributed in anoxic sediments as a result of plant material decomposition and is constantly attracting attention as an interesting substrate for anaerobes like acetogens that can convert bio‐renewable methanol into value‐added chemicals.

Competition Between Chemolithotrophic Acetogenesis and Hydrogenotrophic Methanogenesis for Exogenous H2/CO2 in Anaerobically Digested Sludge: Impact of Temperature

Frontiers in Microbiology, 2019
Anaerobic digestion is a widely applied technology for sewage sludge treatment. Hydrogen and CO2 are important degradation products, which serve as substrates for both hydrogenotrophic methanogenesis and chemolithotrophic acetogenesis.

Methanogenesis and Acetogenesis in Hydrogenotrophy with Carbonate Minerals: Dependence on Mineral Surface Area, Biofilm Growth, and Microbial Community. [PDF]

Environ Sci Technol
The production, storage, and use of hydrogen are anticipated to grow substantially to achieve energy and climate goals. Consequently, microbial communities in many terrestrial and subsurface Earth environments could be exposed to elevated hydrogen ...

Metabolic Potential for Reductive Acetogenesis and a Novel Energy-Converting [NiFe] Hydrogenase in Bathyarchaeia From Termite Guts – A Genome-Centric Analysis

Frontiers in Microbiology, 2021
Symbiotic digestion of lignocellulose in the hindgut of higher termites is mediated by a diverse assemblage of bacteria and archaea. During a large-scale metagenomic study, we reconstructed 15 metagenome-assembled genomes of Bathyarchaeia that represent ...

Methanogenesis inhibition remodels microbial fermentation and stimulates acetogenesis in ruminants. [PDF]

Proc Natl Acad Sci U S A
Rumen microbiota enable ruminants to grow on fibrous plant materials, but also produce methane, driving 5% of global greenhouse gas emissions and leading to a loss of gross energy content. Methanogenesis inhibitors such as 3-nitrooxypropanol (3-NOP) decrease methane emissions in ruminants when supplemented in feed.

Patterns of Functional Redundancy and Anaerobic Metabolic Potential Characterise the Skin Microbiome of a Critically Endangered Sawfish [PDF]

Environ Microbiol
The largetooth sawfish skin supports a distinct microbiome enriched in anaerobic metabolic and dormancy potential, consistent with microbial persistence under low‐oxygen conditions. Greater among‐individual taxonomic variability coupled with functional redundancy potential supports a lottery‐like mechanism of microbiome assembly.
