TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Component: The saccharification enzyme consortium comprises glycosidase(s); enzyme(s) from cellulose-hydrolyzing glycosidases, hemicellulose-hydrolyzing glycosidases, starch-hydrolyzing glycosidases, peptidases, lipases, ligninases, or feruloyl esterases; enzyme(s) from cellulases, endoglucanases, exoglucanases, cellobiohydrolases, beta-glucosidases, xylanases, endoxylanases, exoxylanases, beta-xylosidases, arabinoxylanases, mannases, galactases, pectinases, glucuronidases, amylases, alpha-amylases, beta-amylases, glucoamylases, alpha-glucosidases, or isoamylases.    TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Method: The step of contacting the integrated feedstock with the aqueous solution is carried out at 4-200, preferably 90-150degreesC. It is carried out for a time of up to 8 hours. The method may comprise subjecting the biomass to a pretreatment process to produce a pretreated biomass product; adding the alternative feedstream(s) to the pretreated biomass product to produce a first or second integrated feedstock; and contacting the first or second integrated feedstock with the saccharification enzyme consortium under suitable conditions, to produce the fermentable sugar product. The pretreatment process includes contacting the biomass with the aqueous solution comprising ammonia to form a biomass-aqueous ammonia mixture, where the ammonia is present at a concentration at least adequate to maintain alkaline pH of the biomass-aqueous ammonia mixture, where the ammonia is present at less than 12 wt.% relative to dry weight of biomass, and where the dry weight of biomass is at a high solids concentration of greater than or equal to15 wt.% relative to the weight of the biomass-aqueous ammonia mixture. The step of subjecting the biomass to the pretreatment process is carried out at 4-200, preferably 90-150degreesC. It is carried out for a time of up to 8 hours. The ammonia is recycled. The step of contacting the first or second integrated feedstock with the saccharification enzyme consortium is performed at 15-100degreesC and at a pH of 2-11. Stillage is employed to reduce the pH of the pretreated material making it more amenable to saccharification. The fermentable sugars are used to produce value-added chemicals, fuels or other high-value products. Preferred Parameter: The pH of the integrated feedstock-aqueous ammonia mixture or biomass-aqueous ammonia mixture is greater than 8.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The dry weight of integrated feedstock is at an initial concentration of greater than or equal to15-80, preferably greater than or equal to15-60%. The biomass is the integrated feedstock. It comprises alternative feedstream(s). The dry weight of biomass is at an initial concentration of greater than or equal to15-80, preferably greater than or equal to15-60%. The ammonia is present at less than 10, preferably less than or equal to6 wt.% relative to the dry weight of the integrated feedstock. The alternative feedstream comprises stillage. It is a co-product, an in-process stream, or a waste stream; or a seed process stream from corn, oats, wheat, barley, rice, canola, sunflower, cotton, pea, soybean, or other legumes. The biomass is from bio-energy crops, agricultural residues, municipal solid waste, industrial solid waste, yard waste, wood, or forestry waste. It is preferably switchgrass, waste paper, sludge from paper manufacture, corn grain, corn cobs, corn husks, corn stover, grasses, wheat, wheat straw, hay, rice straw, sugar cane bagasse, sorghum, soy, trees, branches, roots, leaves, wood chips, sawdust, shrubs and bushes, vegetables, fruits, flowers, or animal manure; or corn cobs, corn stover, corn husks, sugar cane bagasse, switchgrass, wheat straw, hay, barley, barley straw, rice straw, or grasses; or corn cobs, corn stover, or sugar cane bagasse. The ammonia is ammonia gas, ammonium hydroxide, and/or urea. The aqueous solution comprising ammonia further comprises additional base(s).
