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 ...
Design of Low-Cost Ethanol Production Medium From Syngas: An Optimization of Trace Metals for Clostridium Ljungdahlii
(MDPI, 2021-10-25)
[Abstract] Syngas fermentation via the Wood-Ljungdahl (WL) pathway is a promising approach for converting gaseous pollutants (CO and CO2) into high-value commodities. Because the WL involves several enzymes with trace metal ...
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 ...
Reactor Designs and Configurations for Biological and Bioelectrochemical C1 Gas Conversion: A Review
(MDPI, 2021-11-07)
[Abstract] Microbial C1 gas conversion technologies have developed into a potentially promising technology for converting waste gases (CO2, CO) into chemicals, fuels, and other materials. However, the mass transfer constraint ...
Advances in the development of electrode materials for improving the reactor kinetics in microbial fuel cells
(Elsevier, 2021-12-07)
[Abstract] Microbial fuel cells (MFCs) are an emerging technology for converting organic waste into electricity, thus providing potential solution to energy crises along with eco-friendly wastewater treatment. The electrode ...
Influence of feedstock mix ratio on microbial dynamics during acidogenic fermentation for polyhydroxyalkanoates production
(Elsevier, 2021-12-01)
[Abstract] The nature of microbial populations plays an essential role in the production of volatile fatty acids (VFA) during acidogenesis, the first stage in polyhydroxyalkanoates (PHA) production using mixed cultures. ...
Bioprocesses for resource recovery from waste gases: Current trends and industrial applications
(Elsevier, 2021-12-27)
[Abstract] Air pollution is a topic of important global concern because it has contributed significantly to an increase in the earth's global warming potential and contributed to severe health and environmental impacts. ...
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 ...
Accumulation of Lipids by the Oleaginous Yeast Yarrowia Lipolytica Grown on Carboxylic Acids Simulating Syngas and Carbon Dioxide Fermentation
(Elsevier, 2022-07-19)
[Abstract] Volatile fatty acids (VFAs) can be considered as low-cost carbon substrates for lipid accumulation by oleaginous yeasts. This study demonstrates that a common mixture of VFAs, typically obtained from the anaerobic ...
