  • Patent number: 10337074
    Abstract: A method of gaseous substrate fermentation comprising: adding gaseous substrate comprising carbon monoxide (CO) and hydrogen (H2) into an aqueous medium in a bioreactor; said method comprising measuring conversion of CO; measuring conversion of H2; increasing flow of gaseous substrate by a preselected flow factor; wherein agitation comprises greater than or equal to target agitation rate.

  • Publication number: 20190040418
    Abstract: A process is provided for fermentation of syngas that is effective for reducing conductivity and providing an alcohol STY of about 10 g ethanol/(L·day). The process includes introducing the syngas into a reactor vessel and providing a nitrogen feed rate to the reactor vessel of about 100 mg or more nitrogen/gram of cells produced. Fermentation of the syngas is effective for providing a fermentation medium having an average conductivity of about 16 mS/cm or less and an STY of 10 g ethanol/(L·day) or more.

  • Patent number: 10100336
    Abstract: A process for fermenting syngas and a fermentation medium provides high ethanol productivity while removing medium components that were previously thought to be essential. The process is effective for providing a specific STY of at least about 1 g ethanol/(L·day·gram cells). In this aspect, the fermentation medium has less than about 1.04 ppm boron, less than about 0.16 ppm manganese, less than about 0.26 ppm molybdenum, or less than about 0.16 ppm copper.
