Energy Conservation in the Acetogenic Bacterium Clostridium aceticum

Microorganisms, 2021
In times of global warming caused by the extensive use of fossil fuels, the need to capture gaseous carbon compounds is growing bigger. Several groups of microorganisms can fix the greenhouse gas CO2.

Revealing formate production from carbon monoxide in wild type and mutants of Rnf‐ and Ech‐containing acetogens, Acetobacterium woodii and Thermoanaerobacter kivui

Microbial Biotechnology, 2020
Summary Acetogenic bacteria have gained much attraction in recent years as they can produce different biofuels and biochemicals from H2 plus CO2 or even CO alone, therefore opening a promising alternative route for the production of biofuels from ...

Metabolic changes of the acetogen Clostridium sp. AWRP through adaptation to acetate challenge

Frontiers in Microbiology, 2022
In this study, we report the phenotypic changes that occurred in the acetogenic bacterium Clostridium sp. AWRP as a result of an adaptive laboratory evolution (ALE) under the acetate challenge. Acetate-adapted strain 46 T-a displayed acetate tolerance to

No acetogen is equal: Strongly different H ₂ thresholds reflect diverse bioenergetics in acetogenic bacteria

Environmental Microbiology, 2023
Abstract Acetogens share the capacity to convert H 2 and CO 2 into acetate for energy conservation (ATP synthesis). This reaction is attractive for applications, such as gas fermentation and microbial electrosynthesis. Different H

Valorization of C1 gases to value-added chemicals using acetogenic biocatalysts

, 2022
In times of global warming and upcoming fossil fuel shortages, the demand for the replacement of current fossil fuel-based chemical production via the development of alternative technologies and sustainable resources has increased. As a possible solution,

Sporulation in solventogenic and acetogenic clostridia

, 2021
The Clostridium genus harbors compelling organisms for biotechnological production processes; while acetogenic clostridia can fix C1-compounds to produce acetate and ethanol, solventogenic clostridia can utilize a wide range of carbon sources to produce ...

CO2-Fixation Strategies in Energy Extremophiles: What Can We Learn From Acetogens?

Frontiers in Microbiology, 2020
Domestication of CO2-fixation became a worldwide priority enhanced by the will to convert this greenhouse gas into fuels and valuable chemicals. Because of its high stability, CO2-activation/fixation represents a true challenge for chemists.
