Biological conversion of carbon monoxide to ethanol: Effect of pH, gas pressure, reducing agent and yeast extract
(Elsevier, 2012-06)
A two-level full factorial design was carried out in order to investigate the effect of four factors on the bioconversion of carbon monoxide to ethanol and acetic acid by Clostridium autoethanogenum: initial pH (4.75–5.75), ...
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 ...
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 ...
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 ...
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 ...
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. ...
Effect of pH, Yeast Extract and Inorganic Carbon on Chain Elongation for Hexanoic Acid Production
(Elsevier, 2019-12-29)
[Abstract] Several anaerobic bioconversion technologies produce short chain volatile fatty acids and sometimes ethanol, which can together be elongated to hexanoic acid (C6 acid) by Clostridium kluyveri in a secondary ...
