Reverse-Engineered Gas-Fermenting Acetogen Strains Recover Enhanced Phenotypes From Autotrophic Adaptive Laboratory Evolution. [PDF]

Microb Biotechnol
We used reverse genetic engineering of the gas‐fermenting model‐acetogen Clostridium autoethanogenum to recover enhanced phenotypes from autotrophic adaptive laboratory evolution. Reverse‐engineered strains were characterised at systems level and bioinformatics suggest that the targeted genes may be involved in overlapping regulatory networks ...

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 [PDF]

, 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. Aus diesem Grund finden Technologien zur Bindung, Speicherung und Wiederverwertung von CO2 immer größere Aufmerksamkeit und diverse chemische als ...

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

Abstract Given recent interest in hydrogen (H 2 ) as a medium for storing and transporting renewable energy, the ability of acetogenic bacteria to use H 2 to directly fix carbon dioxide (CO 2 ) shows great ...

Screening of conditions for the acetic acid production from H2 and CO2 by Thermoanaerobacter kivui in a pressurized stirred tank bioreactor

Chemical Engineering Journal
Growing concerns regarding climate change have heightened interest in utilizing carbon dioxide as a valuable carbon source for chemical production. The acetogen Thermoanaerobacter kivui is a thermophilic bacterium that converts CO2 and H2 streams into acetic acid.

Function of energy-converting hydrogenases and transhydrogenase in the metabolism of the thermophilic acetogenic bacterium Thermoanaerobacter kivui

Der Elektronentransfer zwischen H₂, Ferredoxin, NADH und NADPH ist essenziell für das Redox-Gleichgewicht und den Energiestoffwechsel in Thermoanaerobacter kivui. Die Hydrogenasen Ech1 und Ech2 sind wichtig für die Energiekonservierung auf H₂/CO₂ oder CO.

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.

Renewable Hydrogen Production and Storage Via Enzymatic Interconversion of CO2 and Formate with Electrochemical Cofactor Regeneration

ChemSusChem, Volume 16, Issue 17, September 8, 2023., 2023
Formic acid (FA) is a promising hydrogen carrier. Formate dehydrogenase catalyzes the CO2 reduction to FA with need of a cofactor that can be regenerated efficiently in a bioelectrochemical system. Bacterial enzyme complexes are capable of dehydrogenating FA to produce hydrogen.

Production of biofuels from C1‐gases with Clostridium and related bacteria—Recent advances

Microbial Biotechnology, Volume 16, Issue 4, Page 726-741, April 2023., 2023
The manuscript reviews different routes, as well as their main characteristics, for the production of biofuels with Clostridia and related bacteria. Abstract Clostridium spp. are suitable for the bioconversion of C1‐gases (e.g., CO2, CO and syngas) into different bioproducts.
