Title (EN) PRODUCTION OF ALCOHOL ESTERS AND IN SITU PRODUCT REMOVAL DURING ALCOHOL FERMENTATION
(FR) PRODUCTION D'ESTERS D'ALCOOL ET ÉLIMINATION DU PRODUIT IN SITU PENDANT UNE FERMENTATION ALCOOLIQUE
Abstract: front page image
(EN)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.
(FR)La présente invention a pour objet une composition et un procédé de fermentation alcoolique qui comprend la production d'esters d'alcool par estérification d'un produit d'alcool dans un milieu de fermentation avec un acide carboxylique (par exemple un acide gras) et un catalyseur (par exemple une lipase) capable d'estérifier le produit d'alcool, tel que le butanol, avec l'acide carboxylique pour former les esters d'alcool. Les esters d'alcool peuvent être extraits du milieu de fermentation, et le produit d'alcool récupéré à partir des esters d'alcool. L'acide carboxylique peut également servir de solvant d'extraction pour l'élimination des esters d'alcool du milieu de fermentation.
