Hydrogen-Cycling during Solventogenesis in Clostridium acetobutylicum American Type Culture Collection (ATCC) 824 Requires the [NiFe]-Hydrogenase for Energy Conservation [PDF]
Fermentation, 2018 Clostridium acetobutylicum has traditionally been used for production of acetone, butanol, and ethanol (ABE). Butanol is a commodity chemical due in part to its suitability as a biofuel; however, the current yield of this product from biological systems ...

Production of biofuels from C1‐gases with Clostridium and related bacteria—Recent advances [PDF]
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.

Synergies revealed: RNA-seq study of C. acetobutylicum and C. carboxidivorans co-cultured in the presence of conductive materials [PDF]
Microbiology SpectrumCo-cultures can improve substrate utilization and product yields, yet the dynamics between species remain highly variable and poorly understood. In this study, we investigated the metabolic and transcriptional interplay between Clostridium acetobutylicum

Effect of salinity on C1-gas fermentation by Clostridium carboxidivorans producing acids and alcohols [PDF]
AMB Express, 2019 Clostridium carboxidivorans can produce acids and/or alcohols through syngas fermentation. In that C1-gas fermentation process, the production of acids takes place at higher pH (acetogenesis) (e.g., around 6.00), while the conversion of accumulated acids

Enforcing ATP hydrolysis enhanced anaerobic glycolysis and promoted solvent production in Clostridium acetobutylicum [PDF]
Microbial Cell Factories, 2021 Background The intracellular ATP level is an indicator of cellular energy state and plays a critical role in regulating cellular metabolism. Depletion of intracellular ATP in (facultative) aerobes can enhance glycolysis, thereby promoting end product ...
