Fermentation systems and methods with substantially uniform volumetric uptake rate of a reactive gaseous component

Abstract

Under one aspect, a fermentation system includes a fermentation vessel having a straight wall length L and an inner diameter D. The fermentation system also can include a source of a gas including a reactive gaseous component. The fermentation system also can include spargers spaced apart from one another along the straight wall length L of the fermentation vessel and configured to introduce bubbles of the gas into fermentation broth within the fermentation vessel. The release of the bubbles of the gas by each of the spargers can establish a respective mixing zone within the fermentation broth within the fermentation vessel. Each mixing zone can have substantially the same volumetric uptake rate of the reactive gaseous component by the fermentation broth as each other mixing zone.
