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.

Environmental Microbiology Reports, Volume 15, Issue 2, Page 129-141, April 2023., 2023 Abstract Acetogens are anaerobes using Wood–Ljungdahl pathway (WLP) as the terminal electron acceptor for both assimilation and dissimilation of CO2 and widely distributed in diverse habitats. However, their habitat adaptation is often unclear. Given that bacterial genome evolution is often the result of environmental selective pressure, hereby we ...

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

Formate metabolism in the acetogenic bacterium Acetobacterium woodii
Environmental Microbiology, Volume 23, Issue 8, Page 4214-4227, August 2021., 2021 Summary Acetogenic bacteria are already established as biocatalysts for production of high‐value compounds from C1 substrates such as H2 + CO2 or CO. However, little is known about the physiology, biochemistry and bioenergetics of acetogenesis from formate, an interesting feedstock for biorefineries.

Environmental Microbiology, Volume 23, Issue 8, Page 4661-4672, August 2021., 2021 Summary Lactate is a universal metabolite and energy source, yet the mode of lactate metabolism in many strictly anaerobic microorganisms is still enigmatic. This sparked us to investigate the biochemistry and bioenergetics of lactate metabolism in the model acetogenic bacterium Moorella thermoacetica.

Formyltetrahydrofolate Synthetase Gene Diversity in the Guts of Higher Termites with Different Diets and Lifestyles [PDF]
, 2011 In this study, we examine gene diversity for formyl-tetrahydrofolate synthetase (FTHFS), a key enzyme in homoacetogenesis, recovered from the gut microbiota of six species of higher termites.

Blending industrial blast furnace gas with H 2 enables Acetobacterium woodii to efficiently co-utilize CO, CO2 and H2 [PDF]
, 2021 In this study, the impact of gas composition (i.e. CO, CO2 and H2 partial pressures) on CO2 utilization, growth, and acetate production was investigated in batch and continuous cultures of A. woodii.
