TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Method: In the method (M3), the fermenting of the cellulosic material produces a fermentation product. The method (M3) further involves: recovering the fermentation product from the fermentation. The liquor is obtained from a material that is the same as the cellulosic material subjected to saccharification by the enzyme composition; is obtained from a material that is different than the cellulosic material subjected to saccharification by the enzyme composition; is obtained from a material that is the same as the cellulosic material subjected to saccharification by the enzyme composition, and the treatment conditions used to produce the liquor are different from the pretreatment conditions of the cellulosic material; is obtained from a material that is the same as the cellulosic material subjected to saccharification by a cellulase composition, and the treatment conditions used to produce the liquor are the same as the pretreatment conditions of the cellulosic material; is obtained from a material that is the same as the cellulosic material subjected to saccharification by the enzyme composition, and the treatment conditions used to produce the liquor are the same as the pretreatment conditions of the cellulosic material, and the liquor is further processed to remove cellulose inhibitors; is obtained from a material that is different than the cellulosic material subjected to saccharification by the enzyme composition, and the treatment conditions used to produce the liquor are different from the pretreatment conditions of the cellulosic material; is obtained from a material that is different than the cellulosic material subjected to saccharification by the enzyme composition, and the treatment conditions used to produce the liquor are the same as the pretreatment conditions of the cellulosic material; is obtained from a material that is different than the cellulosic material subjected to saccharification by the enzyme composition, and the treatment conditions used to produce the liquor are the same as the pretreatment conditions of the cellulosic material, and the liquor is further processed to remove cellulose inhibitors; is obtained from a lignocellulose material, hemicellulose material, lignacious material, monosaccharides of the lignocellulose material and/or monosaccharides of the hemicellulose material. The liquor is further processed to remove inhibitors of a cellulase and/or hemicellulase. Preferred Components: The enzyme composition comprises at least one enzyme selected from a cellulase, hemicellulase, esterase, expansin, laccase, ligninolytic enzyme, pectinase, peroxidase, protease, and swollenin.    TECHNOLOGY FOCUS - POLYMERS - Preferred Method: The method (M1) further involves: recovering the degraded cellulosic material. EXAMPLE - No suitable example given.
