Latest Patents

One of Liu's latest patents focuses on the management of ethanol concentration during syngas fermentation. This innovative process involves inoculating a medium to create an inoculated medium, which is then contacted with syngas. The cells and medium are subsequently removed and separated to yield concentrated cells and permeate. Ethanol is extracted from the permeate, resulting in both ethanol and a reduced ethanol aqueous stream, which is returned to the fermentation process. Another notable patent addresses the control of conductivity in anaerobic fermentation. This process effectively manages medium conductivity during the fermentation of a CO-containing gaseous substrate while achieving a specific productivity of about 10 g ethanol per liter per day or more. It includes balancing medium conductivity, specific carbon uptake, or cell density levels.
