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 gram of ethanol/(L·day·gram cells) and for providing a selenium content in cell biomass exiting the fermentation of about 1 ppm or less.
