Automated process control for co bioconversions

Control processes are provided for enhancing biological processes for converting gaseous substrates to useful end products such as ethanol. A process includes providing a gaseous substrate comprising one or more of CO and CO2 to a bioreactor at a substrate addition rate. Acetogenic bacteria provided...

Beschreibung
Zusammenfassung:	Control processes are provided for enhancing biological processes for converting gaseous substrates to useful end products such as ethanol. A process includes providing a gaseous substrate comprising one or more of CO and CO2 to a bioreactor at a substrate addition rate. Acetogenic bacteria provided to the bioreactor ferment the gaseous substrate in a fermentation broth. The process includes determining a concentration of carboxylic acids and/or carboxylates in the fermentation broth. A control algorithm uses those concentrations to adjust the gaseous substrate addition rate.
