Acetogenic production of 3-Hydroxybutyrate using a native 3-Hydroxybutyryl-CoA Dehydrogenase
Frontiers in Microbiology, 2022 3-Hydroxybutyrate (3HB) is a product of interest as it is a precursor to the commercially produced bioplastic polyhydroxybutyrate. It can also serve as a platform for fine chemicals, medicines, and biofuels, making it a value-added product and feedstock.

CO Metabolism in the Acetogen Acetobacterium woodii [PDF]
Applied and Environmental Microbiology, 2015 ABSTRACT The Wood-Ljungdahl pathway allows acetogenic bacteria to grow on a number of one-carbon substrates, such as carbon dioxide, formate, methyl groups, or even carbon monoxide. Since carbon monoxide alone or in combination with hydrogen and carbon dioxide (synthesis gas) is an increasingly important feedstock for third ...

Sodium bioenergetics in methanogens and acetogens [PDF]
FEMS Microbiology Letters, 1990 Recent investigations with Methanosarcina barkeri elucidated the role of sodium ions in the energy metabolism of methanogenic bacteria and provided evidence for a novel mechanism of energy transduction with Na+ as the coupling ion. During methanogenesis from methanol, an eletrochemical sodium gradient generated by a Na+/H+ antiporter is used as the ...

Accelerate acetogenic bioproduction: Acetogens as sustainable producers of biocommodities
Current Opinion in Systems BiologyGas fermentation using autotrophic acetogenic bacteria has been industrialized, however, its full potential remains untapped, with only native products like ethanol being produced thus far. Advancements in synthetic biology have enabled the recombinant production of diverse biocommodities to broaden their limited natural product spectrum from C1-gases.

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 ...

The role of acetogens in microbially influenced corrosion of steel [PDF]
Frontiers in Microbiology, 2014 Microbially influenced corrosion (MIC) of iron (Fe(0)) by sulfate-reducing bacteria (SRB) has been studied extensively. Through a mechanism, that is still poorly understood, electrons or hydrogen (H2) molecules are removed from the metal surface and used as electron donor for sulfate reduction.
