Abstract
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.
