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,...

Feedback control of gas supply for ethanol production via syngas fermentation

BACKGROUND Synthesis gas, syngas, fermentation uses carbon monoxide (CO) and hydrogen (H2) to produce valuable alcohols like ethanol, with companies such as INEOS Bio and LanzaTech piloting large-scale facilities. Achieving economic viability in this process requires stable, high-yield alcohol production over long periods, which depends on carefully...

Development of Novel Biocatalytic Conversion Process for Production of Alcohols, Ketones and Organic Acids

BACKGROUND As energy demand increases, efficiently produced biofuels such as ethanol will be preferred over fossil fuels due to their reduced costs. One such biofuel, butanol, has several technical advantages over ethanol including a higher energy density. Butanol is traditionally produced using molasses and starch in the acetone-butanol-ethanol (A-B-E)...
