Abstract

An alcohol fermentation process and composition that includes production of alcohol esters by esterification of product alcohol in a fermentation medium with a carboxylic acid (e.g., fatty acid) and a catalyst (e.g., lipase) capable of esterifying the product alcohol, such as butanol, with the carboxylic acid to form the alcohol esters. The alcohol esters can be extracted from the fermentation medium, and the product alcohol recovered from the alcohol esters. The carboxylic acid can also serve as an extractant for removal of the alcohol esters from the fermentation medium.
