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 ...
Biological conversion of carbon monoxide: rich syngas or waste gases to bioethanol
(Wiley-Blackwell, 2011)
Bioconversion of syngas/waste gas components to produce ethanol appears to be a promising alternative compared to the existing chemical techniques. Recently, several laboratory-scale studies have demonstrated the use of ...
Carbon monoxide fermentation to ethanol by Clostridium autoethanogenum in a bioreactor with no accumulation of acetic acid
(Elsevier, 2015-06)
[Abstract] Fermentation of CO or syngas offers an attractive route to produce bioethanol. However, during the bioconversion, one of the challenges to overcome is to reduce the production of acetic acid in order to minimize ...
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 ...
Polyhydroxyalkanoates Production From Syngas Fermentation Effluents: Effect of Nitrogen Availability
(Elsevier, 2021-10-29)
[Abstract] Syngas fermentation is a promising technology for bioalcohols production even though some produced volatile fatty acids (VFA) may remain unconsumed in the effluent. The present research explored the production ...
Recent Trends in Biogenic Gas, Waste and Wastewater Fermentation [Editorial]
(MDPI, 2022)
[Abstract] In recent years, the optimization of bioprocesses for the removal of pollutants from industrial biogenic gas emissions, waste and wastewater has been the focus of intensive research. Recently developed technologies ...
Engineering Acetobacterium woodii for the Production of Isopropanol and Acetone From Carbon Dioxide and Hydrogen
(Wiley, 2022-01-25)
[Abstract] The capability of four genetically modified Acetobacterium woodii strains for improved production of acetone from CO2 and hydrogen was tested. The acetone biosynthesis pathway was constructed by combining genes ...
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 ...
Enhanced solventogenesis in syngas bioconversion: Role of process parameters and thermodynamics
(Elsevier, 2022)
[Abstract] Biofuels, such as ethanol and butanol, obtained from carbon monoxide-rich gas or syngas bioconversion (solventogenesis) are an attractive alternative to traditional fermentation processes with merits of no ...
State-of-the-art in the accumulation of lipids and other bioproducts from sustainable sources by Yarrowia lipolytica
(Springer Link, 2023)
[Abstract] Energy and environmental issues related to conventional fossil-derived products and fuels have led researchers to focus on alternative, more environmentally-friendly processes, such as the production of microbial ...
