CO₂fixation in acetogenic bacteria: Variations on a theme [PDF]

FEMS Microbiology Letters, 1986
An increasing number of strict anaerobic bacteria are being found which use an alternative pathway to the ubiquitous Calvin cycle for CO2 fixation into cell compounds and the ubiquitous Krebs cycle for acetyl CoA oxidation to CO2. The principles of this non-cyclic pathway, the acetyl CoA pathway, have long been studied in acetogenic bacteria.

Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization

ChemBioEng Reviews, Volume 13, Issue 2, April 2026.
The review article begins with an introduction that covers the overview, food waste (FW) classification, and the steps involved in producing biogas through anaerobic digestion (AD). Following that, it describes the process for producing biogas, including single‐, two‐, and multistage systems, mesophilic and thermophilic digestion, and wet and dry ...

Bioprocesses for the treatment and valorisation of gas emissions, odours, volatile compounds and greenhouse gases

Frontiers in Environmental Engineering
Different bioprocesses for the treatment as well as the valorisation of waste gases and greenhouse gases are briefly reviewed. Biotreatment technologies are based on the use of bioreactors for waste gas treatment, e.g., biofilter, biotrickling filter ...

Formic Acid Formation by Clostridium ljungdahlii at Elevated Pressures of Carbon Dioxide and Hydrogen

Frontiers in Bioengineering and Biotechnology, 2018
Low productivities of bioprocesses using gaseous carbon and energy sources are usually caused by the low solubility of those gases (e.g., H2 and CO).

Genomic and Transcriptomic Insights Into the Autotrophic Metabolism on H2 + CO2 or CO of the Thermophilic Acetogenic Model Organism Moorella thermoacetica

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Moorella thermoacetica is the model organism for elucidation of acetogenesis. The reduction of CO2 to acetate is well studied, but how redox carrier balancing and energy conservation are maintained during autotrophic growth and how H2 is oxidised remains enigmatic.

Methane Generation Using an Anaerobic Biodigester From Waste Leachate Water

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 2, March/April 2026.
ABSTRACT Leachate wastewater (LWW) is characterized by slow biodegradation and low biogas production due to resistant materials and limited biological activity. Therefore, applying pretreatments is essential to improving biodegradation potential, which consequently boosts energy recovery.

Methanol and methyl group conversion in acetogenic bacteria: biochemistry, physiology and application

FEMS Microbiology Reviews, 2020
ABSTRACTThe production of bulk chemicals mostly depends on exhausting petroleum sources and leads to emission of greenhouse gases. Within the last decades the urgent need for alternative sources has increased and the development of bio-based processes received new attention.

Increasing the succinate yield in Actinobacillus succinogenes by fumigation of H2 in a bioreactor

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 591-605, March/April 2026.
Abstract The microbial conversion of CO2 into value‐added chemicals offers a promising and scalable route for sustainable bioproduction, particularly under mild reaction conditions and with technically straightforward reactor configurations. Actinobacillus succinogenes, a natural succinate producer, can fix CO2 through anaplerotic carboxylation but its

Comparative Physiology and Genomics of Thermincola and Carboxydocella Strains and Description of Two Novel Isolates

Environmental Microbiology, Volume 28, Issue 3, March 2026.
Two novel thermophilic bacteria, Thermincola strain AZ34E and Carboxydocella strain AZ29I, were isolated from hydrothermal environments and shown to oxidise carbon monoxide via the water‐gas shift reaction. Comparative genomic and phylogenetic analyses revealed that all currently described isolates within Thermincola and Carboxydocella each represent a
