Abstract
A method of operating a fermentation zone for the production of ethanol from syngas uses a crotonate derivative to prevent or reverse the effects of butyrigen contamination. The crotonate compound works in continuous fermentation processes to reduce or eliminate contamination from butyrate and butanol in the syngas derived ethanol product.
