Patent number: 8058041Abstract: A process for simultaneous saccharification and fermentation of a cellulosic solids fraction extracted from a lignocellulosic feedstock. The viscosity of the cellulosic solids fraction is reduced by intermixing with a liquid carbohydrate stream. A suitable liquid carbohydrate stream is a de-lignified liquids fraction that was previously separated from the solids fraction during processing of the lignocellulosic feedstock. Alternatively, the viscosity of the solids fraction may be reduced by commingling with a liquid carbohydrate stream comprising one or more monosaccharides. The reduced-viscosity cellulosic solids fraction is then commingled with a fermentative microbial inoculant and a cellulosic biomass-degrading enzyme composition. The commingled mixture is maintained in a pressurized reaction vessel under elevated temperatures to enable simultaneous enzymatic hydrolysis of the cellulosic solids to monosaccharides and fermentation of the monosaccharides to produce an ethanolic beer.Type: GrantFiled: July 3, 2008Date of Patent: November 15, 2011Inventors: Alex Berlin, Edward Kendall Pye, Donald O'Connor
