TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The biomass is derived from corn grain, corn cobs, crop residues such as 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, components obtained from milling of grains, cellulosic material, lignocellulosic material, trees, branches, roots, leaves, wood chips, sawdust, shrubs and bushes, vegetables, fruits, flowers and/or animal manure.    TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Components: The recombinant microorganism has at least one pyruvate decarboxylase (PDC) gene deletion. The substance comprise at least one enzyme (preferably lipase). Preferred Method: In the method (M1), the steps B and C occurs simultaneously. The fermentable carbon source is derived from the biomass. In the method (M2), the step b) involves: contacting the oil with at least one substance capable of hydrolyzing the portion of the oil into fatty acids. The method (M2) further involves: prior to step c), inactivating the enzymes after at least a portion of the oil is hydrolyzed; fermenting the fermentable carbon source to produce product alcohol; separating the oil from the biomass prior to the step b) of converting at least a portion of the oil into fatty acids; liquefying the biomass to produce a liquefied biomass, where the liquefied biomass comprises oligosaccharides; and contacting the liquefied biomass with a saccharification enzyme capable of converting oligosaccharides into fermentable sugar to form a saccharified biomass. At least one of steps (b), (c), and (d) occurs in the fermentation vessel and simultaneously. The step c) involves: contacting the saccharified biomass with the fermentation broth comprising a recombinant microorganism. The step d1) involves: contacting the oil with at least one substance capable of hydrolyzing the portion of the oil into fatty acids.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The fatty acids are selected from oleic acid, palmitic acid and/or myristic acid. The fermentation broth further comprises ethanol.
