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.

Microbial Electrosynthesis Reshapes Energy Metabolism and Physiology in Clostridium ljungdahlii. [PDF]

Microb Biotechnol
Microbial electrosynthesis drives Clostridium ljungdahlii into a distinct stress‐associated physiological state, different from gas fermentation. Comparative multi‐omics and electron microscopy reveal physiological constraints that help explain the poor performance of MES.

Comparative Microbiome Analysis Reveals the Ecological Relationships Between Rumen Methanogens, Acetogens, and Their Hosts

Frontiers in Microbiology, 2020
Ruminant methane, which is generated by methanogens through the consumption of hydrogen and supports the normal function of the rumen ecosystem, is a major source of greenhouse gases.

Accelerate acetogenic bioproduction: Acetogens as sustainable producers of biocommodities

Current Opinion in Systems Biology
Gas 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.

Advanced aspects of acetogens

Bioresource Technology
Acetogens 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 ...

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 ...

The Metabolism of Clostridium ljungdahlii in Phosphotransacetylase Negative Strains and Development of an Ethanologenic Strain

Frontiers in Bioengineering and Biotechnology, 2020
The sustainable production of chemicals from non-petrochemical sources is one of the greatest challenges of our time. CO2 release from industrial activity is not environmentally friendly yet provides an inexpensive feedstock for chemical production.

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 ...
