Bioresource TechnologyAcetogens are a diverse group of anaerobic bacteria that are capable of carbon dioxide reduction and have for long fascinated scientists due to their unique metabolic prowess. Historically, acetogens have been recognized for their remarkable ability to grow and to produce acetate from different one-carbon sources, including carbon dioxide, carbon ...

Hydrogenotrophic culture enrichment reveals rumenLachnospiraceaeandRuminococcaceaeacetogens and hydrogen-responsiveBacteroidetesfrom pasture-fed cattle [PDF]
FEMS Microbiology Letters, 2015 Molecular information suggests that there is a broad diversity of acetogens in the rumen, distinct from any currently isolated acetogens. We combined molecular analysis with enrichment culture techniques to investigate this diversity further.

Acetogen and acetogenesis for biological syngas valorization
Bioresource Technology, 2023The bioconversion of syngas using (homo)acetogens as biocatalysts shows promise as a viable option due to its higher selectivity and milder reaction conditions compared to thermochemical conversion. The current bioconversion process operates primarily to produce C2 chemicals (e.g., acetate and ethanol) with sufficient technology readiness levels (TRLs)

General medium for the autotrophic cultivation of acetogens
Bioprocess and Biosystems Engineering, 2016Syngas fermentation, a microbial process in which synthesis gas serves as a substrate for acetogens, has attracted increasing interest in the last few years. For the purposeful selection of acetogens for various applications, it would be useful to characterize and compare the process performances of as many autotrophic strains as possible under ...

Sugar phosphorylation activity in ruminal acetogens
Journal of Environmental Science and Health - Part A Toxic/Hazardous Substances and Environmental Engineering, 2012Acetogenic bacteria Acetitomaculum ruminis, Acetobacterium woodii, and Eubacterium limosum were compared for phosphoenolpyruvate (PEP) and ATP-dependent phosphorylation of glucose and 2-deoxy-glucose. Rate of phosphorylation activity was measured in toluene-treated acetogenic cells using PEP and ATP and radiolabled glucose or 2-deoxy glucose ...

Limitation of syntrophic coculture growth by the acetogen
Biotechnology and Bioengineering, 2015ABSTRACTThe syntrophic cooperation between hydrogen‐producing acetogens and hydrogenotrophic methanogens relies on a critical balance between both partners. A recent study, provided several indications for the dependence of the biomass‐specific growth rate of a methanogenic coculture on the acetogen.
