Method to sustain culture activity, gas uptake and improve selectivity for ethanol production during syngas or producer gas fermentation in bioreactors

BACKGROUND Global energy demand continues to rise while fossil fuel reserves decline, heightening the need for sustainable alternatives such as biofuels. Syngas- a mixture of carbon monoxide (CO), hydrogen (H2), and carbon dioxide (CO2)- can be biologically converted into valuable chemicals including alcohols through microbial fermentation. However,...
