Effect of Endogenous and Exogenous Butyric Acid on Butanol Production From CO by Enriched Clostridia
(Frontiers, 2022-02-16)
[Abstract] Butanol is a potential renewable fuel. To increase the selectivity for butanol during CO fermentation, exogenous acetic acid and ethanol, exogenous butyric acid or endogenous butyric acid from glucose fermentation ...
Optimization of the treatment of carbon monoxide-polluted air in biofilters
(Elsevier, 2009-01)
This work is the first extensive study on the removal of carbon monoxide from polluted air in biofilters. It compares the performance of two packing materials, namely lava rock alone and a mixture of peat and lava rock. ...
Effect of salinity on C1-gas fermentation by "Clostridium carboxidivorans" producing acids and alcohols
(Springer Nature, 2019-07-17)
[Abstract] 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), ...
Removal of formaldehyde, methanol, dimethylether and carbon monoxide from waste gases of synthetic resin-producing industries
(Elsevier, 2008-02)
The removal of mixtures of gas-phase pollutants released from formaldehyde- and formaldehyde resin-producing industries was studied in different bioreactor systems. The waste gases contained formaldehyde, methanol, ...
Ethanol and Acetic Acid Production from Carbon Monoxide in a Clostridium Strain in Batch and Continuous Gas-Fed Bioreactors
(Multidisciplinary Digital Publishing Institute, 2015)
The effect of different sources of nitrogen as well as their concentrations on the bioconversion of carbon monoxide to metabolic products such as acetic acid and ethanol by Clostridium autoethanogenum was studied. In a ...
Selective Butanol Production From Carbon Monoxide by an Enriched Anaerobic Culture
(Elsevier, 2021-09-25)
[Abstract] An anaerobic mixed culture able to grow on pure carbon monoxide (CO) as well as syngas (CO, CO2 and H2), that produced unusual high concentrations of butanol, was enriched in a bioreactor with intermittent CO ...
Autotrophic (C₁-Gas) Versus Heterotrophic (Fructose) Accumulation of Acetic Acid and Ethanol in Clostridium Aceticum
(Elsevier, 2021-07-03)
[Abstract] The influence of the carbon source on the metabolism and growth of Clostridium aceticum was investigated, supplying either CO or fructose as sole carbon source. The acid and solvent production patterns were ...
Two-stage syngas fermentation into microbial oils and β-carotene with Clostridium carboxidivorans and engineered Yarrowia lipolytica
(Elsevier, 2023)
[Abstract] An engineered Yarrowia lipolytica strain was able to simultaneously accumulate microbial oils and β-carotene from both acetic and butyric acids produced from syngas fermentation by Clostridium carboxidivorans, ...
