A Versatile Aldehyde: Ferredoxin Oxidoreductase from the Organic Acid Reducing Thermoanaerobacter sp. Strain X514. [PDF]

Int J Mol Sci
Aldehyde:ferredoxin oxidoreductases (AORs) have been isolated and biochemically-characterized from a handful of anaerobic or facultative aerobic archaea and bacteria. They catalyze the ferredoxin (Fd)-dependent oxidation of aldehydes to acids.

Extremophiles in a changing world. [PDF]

Extremophiles
Extremophiles and their products have been a major focus of research interest for over 40 years. Through this period, studies of these organisms have contributed hugely to many aspects of the fundamental and applied sciences, and to wider and more ...

Knock-down of genes essential for homoacetogenic growth using sugar inducible promoters in the thermophile Thermoanaerobacter kivui

bioRxiv
Given recent interest in hydrogen (H2) as a medium for storing and transporting renewable energy, the ability of acetogenic bacteria to use H2 to directly fix carbon dioxide (CO2) shows great promise.

Genetics and physiology of the thermophilic acetogenic bacteria Thermoanaerobacter kivui lacking key genes coding for electron re-cycling enzymes [PDF]

, 2022
Thermoanaerobacter kivui ist ein thermophiles acetogenes Bakterium, das chemolithoautotroph auf CO2 unter Verwendung von molekularem H2 als Elektronendonor wächst und Acetat als Produkt über den Wood-Ljungdahl-Weg (WLP) bildet.

The hydrogen-dependent CO2 reductase from Acetobacterium woodii and Thermoanaerobacter kivui : Capture and storage of hydrogen and carbon dioxide in formic acid by acetogenic bacteria

, 2022
In Zeiten der globalen Klimaerwärmung und des Klimawandels werden Strategien zur Vermeidung, Reduzierung oder Wiederverwertung von CO2-Emissionen sowie die Abkehr von fossilen Energieträgern immer wichtiger.

Comparative analysis of carbon monoxide tolerance among Thermoanaerobacter species [PDF]

, 2016
An anaerobic thermophilic strain (strain PCO) was isolated from a syngas-converting enrichment culture. Syngas components cannot be used by strain PCO, but the new strain is very tolerant to carbon monoxide (pCO = 1.7 × 105 Pa, 100% CO).

Methanol and Carbon Monoxide Metabolism of the Thermophile Moorella caeni. [PDF]

Environ Microbiol
An omics approach was used to elucidate the C1 metabolism of Moorella caeni DSM 21394 T, which exhibits acetogenic metabolism on methanol and hydrogenogenic metabolism on CO. Our results suggest that respiratory Complex I serves as the primary respiratory enzyme in methanol‐grown cells.

Effects of Nitrate on Hydrogenogenic Carbon Monoxide Oxidation in Parageobacillus thermoglucosidasius. [PDF]

Environ Microbiol Rep
Parageobacillus thermoglucosidasius hierarchically utilises nitrate respiration and hydrogenogenic carbon monoxide (CO) oxidation. Nitrate suppresses CO oxidation and promotes rapid cell growth through hydrogen‐dependent nitrate reduction. For this bacterium, CO serves as a supplemental energy source in environments lacking alternative electron ...

A new metabolic trait in an acetogen: Mixed acid fermentation of fructose in a methylene‐tetrahydrofolate reductase mutant of Acetobacterium woodii

Environmental Microbiology Reports, Volume 15, Issue 5, Page 339-351, October 2023., 2023
Abstract To inactivate the Wood–Ljungdahl pathway in the acetogenic model bacterium Acetobacterium woodii, the genes metVF encoding two of the subunits of the methylene‐tetrahydrofolate reductase were deleted. As expected, the mutant did not grow on C1 compounds and also not on lactate, ethanol or butanediol.
