A process is provided for management of ethanol concentration during syngas fermentation. A process for fermentation of syngas includes inoculating a medium to provide an inoculated medium. Inoculated medium is contacted with syngas and cells and medium are removed and separated to provide concentrated cells and permeate. Ethanol is separated from the permeate to provide ethanol and a reduced ethanol aqueous stream. The reduced ethanol aqueous stream is returned to the fermentation.

Management of ethanol concentration during syngas fermentation

Process are provided which are effective for controlling medium conductivity during fermentation of a CO-containing gaseous substrate while providing an STY of about 10 g ethanol/(L&#xb7;day) or more. The process includes balancing medium conductivity, specific carbon uptake or cell density levels.

Control of conductivity in anaerobic fermentation

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&#xb7;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&#xb7;day) or more.

Method of operation of a syngas fermentation process

A process provides high ethanol productivity levels during fermentation of a CO-containing substrate. The process controls CO-substrate feed rates and cell density to avoid culture upset and CO inhibition. The process includes fermenting a CO-containing gaseous substrate to obtain a target cell density and a target CO feed rate, and then periodically reducing and increasing the CO feed rate.

Process for fermenting co-containing gaseous substrates

A process is provided for fermenting CO-containing gaseous substrates in a low phosphate medium. The process includes blending a liquid medium that includes at least one transition metal element with a liquid medium that includes at least at least one other transition metal element and one non-metal element to provide a fermentation medium. The process is effective for preventing precipitation of one or more transition metal elements with one or more non-metal elements. The fermentation medium used in the process is prepared in a way that requires significantly lower amounts of water and reduced levels of phosphate.

Process for fermenting co-containing gaseous substrates in a low phosphate medium effective for reducing water usage

A process for stable fermentation of CO-containing substrates and improved ethanol productivity includes providing medium components in amounts needed by microorganisms in the fermentation. The process includes determining a potassium concentration in the fermentation medium and providing a first medium and a second medium to the fermentation, the first medium provided at a rate effective for maintaining the potassium in the fermentation medium in a range of about 20 to about 200 mg/L until reaching a target cell density.

Process for controlling fermentation of co-containing substrates

The present disclosure relates to a motion control system for a machine tool system wherein a value of a surface finish quality parameter of the motion control system is adjusted to control the surface finish of a part machined with the machine tool system. The machine tool system may include a conversational mode of operation and a NC mode of operation.
