Carbon monoxide fermentation to ethanol by Clostridium autoethanogenum in a bioreactor with no accumulation of acetic acid [PDF]

, 2015
[Abstract] Fermentation of CO or syngas offers an attractive route to produce bioethanol. However, during the bioconversion, one of the challenges to overcome is to reduce the production of acetic acid in order to minimize recovery costs.

Marine Cold Seep ANME‐2/SRB Consortia Produce Their Lipid Biomass From Inorganic Carbon

Environmental Microbiology, Volume 27, Issue 12, December 2025.
Lipid‐stable isotope probing (SIP) experiments in Astoria Canyon sediments revealed that both ANME‐2 and SRB primarily assimilate dissolved inorganic carbon (DIC or HCO3‐), not methane, into biomass. SRB‐specific lipids showed eightfold higher DI13C‐assimilation than ANME lipids, suggesting SRB directly assimilate DIC, while ANME assimilate an ...

Functional gene analysis suggests different acetogen populations in the Bovine Rumen and Tammar Wallaby Forestomach [PDF]

, 2010
Reductive acetogenesis via the acetyl coenzyme A (acetyl-CoA) pathway is an alternative hydrogen sink to methanogenesis in the rumen. Functional gene-based analysis is the ideal approach for investigating organisms capable of this metabolism (acetogens).

A metagenomics roadmap to the uncultured genome diversity in hypersaline soda lake sediments

Microbiome, 2018
Background Hypersaline soda lakes are characterized by extreme high soluble carbonate alkalinity. Despite the high pH and salt content, highly diverse microbial communities are known to be present in soda lake brines but the microbiome of soda lake ...

Advances in metabolic engineering in the microbial production of fuels and chemicals from C1 gas [PDF]

, 2018
The future sustainable production of chemicals and fuels from non-petrochemical sources, while at the same time reducing greenhouse gas (GHG) emissions, represent two of society's greatest challenges.

Evidence for Trace Gas Metabolism and Widespread Antibiotic Synthesis in an Abiotically Driven, Antarctic Soil Ecosystem

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
We analysed bacterial diversity in 18 shotgun metagenomes from a model soil ecosystem in Antarctica using the VEBA metagenome pipeline. We recovered 701 medium‐to‐high quality MAGs and found that these bacteria metabolise trace gases, produce potentially novel antibiotics and employ extremotolerance phenotypes to survive the extreme Antarctic soil ...

Mitigating methane emissions and promoting acetogenesis in ruminant livestock

Frontiers 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 ...

Reducing Oxygen Stress and Improving Hydrogen Availability Boosts Microbial Electrosynthesis by Clostridium ljungdahlii

ChemSusChem, Volume 18, Issue 21, Novemebr 4, 2025.
Microbial electrosynthesis (MES) from CO2 by acetogens enables the production of value‐added chemicals. However, its current limitations include O2 stress and insufficient H2 availability. Using Clostridium ljungdahlii as a model in 1‐L electrobioreactors providing high process control, MES is boosted to unprecedent acetate concentrations and rates ...

A TetR-Family Protein (CAETHG_0459) Activates Transcription From a New Promoter Motif Associated With Essential Genes for Autotrophic Growth in Acetogens

Frontiers in Microbiology, 2019
Acetogens can fix carbon (CO or CO2) into acetyl-CoA via the Wood–Ljungdahl pathway (WLP) that also makes them attractive cell factories for the production of fuels and chemicals from waste feedstocks.
