Extraction solvents derived from oil for alcohol removal in extractive fermentation

The disclosure relates to a method for producing a product alcohol comprising: (a) providing biomass comprising water, fermentable carbon source, and oil; (b) liquefying the biomass to produce a liquefied biomass; (c) contacting the liquefied biomass with one or more enzymes whereby at least a portion of the oil is hydrolyzed to form an extractant; (d) contacting the liquefied biomass with a saccharification enzyme capable of converting oligosaccharides into fermentable sugar; (e) contacting the liquefied biomass with a fermentation broth in a fermentation vessel; (f) fermenting the carbon source of the liquefied biomass to produce a product alcohol; (g) removing in situ the product alcohol from the fermentation broth by contacting the broth with the extractant; and optionally steps (c) and (d) occur concurrently, wherein the biomass comprises corn grain, corn cobs, crop residues, corn husks, corn stover, grasses, wheat, rye, wheat straw, barley, barley straw, hay, rice straw, switchgrass, waste paper, sugar cane bagasse, sorghum, sugar cane, soy, grains, cellulosic material, lignocellulosic material, trees, branches, roots, leaves, wood chips, sawdust, shrubs and bushes, vegetables, fruits, flowers, animal manure, and mixtures thereof, and wherein the oil comprises glycerides, and wherein the one or more enzymes is selected from esterase, lipase, phospholipase, and lysophospholipase, and wherein a partition coefficient of the extractant for the product alcohol is greater than a partition coefficient of the oil of the biomass for the product alcohol.
