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 ...

Programming Gut Microbiome Function Through Cross‐Feeding: From Ecological Mechanisms to Live Biotherapeutics

Advanced Science, EarlyView.
This graphical abstract presents gut microbial cross‐feeding through a Mechanism–Technology–Application framework. It summarizes major resource‐transfer modes, the experimental and computational tools used to establish causality, and potential interventions involving dietary substrates, live biotherapeutic products, and engineered microbes.

A Metagenome‐Assembled Genome Catalog From the Global Ruminant Microbiomes

Animal Research and One Health, EarlyView.
The Ruminant Gastrointestinal MAG Catalog (RGMC) is a comprehensive global resource offering 40,812 strain‐level genomes across 53 bacterial and 4 archaeal classes. It greatly surpasses prior efforts in scale and diversity, serving as an essential foundation for research in ruminant nutrition, microbial function, and methane mitigation.

Obligate autotrophy at the thermodynamic limit of life in a new acetogenic bacterium

Frontiers in Microbiology, 2023
One of the important current issues of bioenergetics is the establishment of the thermodynamic limits of life. There is still no final understanding of what is the minimum value of the energy yield of a reaction that is sufficient to be used by an ...

Acidogenic fermentation of pretreated food waste under psychrophilic conditions for volatile fatty acids production

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Mixed‐culture fermentation generally produces volatile fatty acids (VFAs) as a mixture of C2–C6 acids. Among operational parameters, temperature has a distinct effect on the microorganisms' metabolic activity, which can shift the composition of the metabolites.

Hydrogenotrophic culture enrichment reveals rumen Lachnospiraceae and Ruminococcaceae acetogens and hydrogen-responsive Bacteroidetes from pasture-fed cattle

, 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.

A functional Wood–Ljungdahl pathway devoid of a formate dehydrogenase in the gut acetogens Blautia wexlerae, Blautia luti and beyond

, 2022
Species of the genus Blautia are typical inhabitants of the human gut and considered as beneficial gut microbes. However, their role in the gut microbiome and their metabolic features are poorly understood. Blautia schinkii was described as an acetogenic

Enrichment of Anaerobic Syngas-Converting Communities and Isolation of a Novel Carboxydotrophic Acetobacterium wieringae Strain JM

Frontiers in Microbiology, 2020
Syngas is a substrate for the anaerobic bioproduction of fuels and valuable chemicals. In this study, anaerobic sludge was used for microbial enrichments with synthetic syngas and acetate as main substrates.

Reducing Cooling Costs for Sustainable Food Biomanufacturing With Thermotolerant Cupriavidus necator H16 Mutant

Biotechnology and Bioengineering, EarlyView.
With a thermotolerant C. necator mutant the SCP production costs can be decreased by $0.98/kg. ABSTRACT Autotrophic CO2 conversion to Single Cell Protein (SCP) using H2 and O2 is gaining commercial traction for food and feed production. Cupriavidus necator H16 is a key chassis organism for this “knallgas” fermentation, but industrial operation is ...

Roles of acetogens and methanogens in carbon capture and storage

, 2013
Carbon capture and storage (CCS) aims to reduce atmospheric CO2 by capturing emitted gas for storage in subsurface locations. Microorganisms such as methanogens and acetogens, can utilize H2 and CO2 as a carbon and energy source in the subsurface.
