TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Component: The mixture does not include amylase. The protease is an acid fungal protease, or Penicillium acid protease, Mucor acid protease, Monascus acid protease, Trichoderma acid protease, Phaeosphaeria acid protease, Rhizopus acid protease, preferably Aspergillus saitoi aspartic protease; and has an amino acid sequence greater than or equal to 95% identical to amino acid sequence of SEQ ID NO: 1, or SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11 or SEQ ID NO: 12 (Sequences not defined here may be found at ftp://ftp.wipo.int/pub/published_pct_sequences/publication). The cellulase comprises endo- beta -1,4-glucanases, exo-cellobiohydrolases, beta -glucosidase (cellobiase) and/or exoglucanases. The hemicellulase comprises endo-1,4- beta -xylanase, beta -xylosidase, beta -endomannanase, beta -mannosidase, pectin lyase, pectate lyase, alpha -L-arabinofuranosidase, alpha -glucuronidases, alpha / beta -galactosidases and/or esterases.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The fiber feedstock is corn stover, corn gluten feed, distillers'dried grains, distillers'dried grains with solubles, switchgrass, soy hulls, wheat chaff or wheat straw. The reaction product further comprises arabinose, xylose, galactose, mannose, cellulobiose, maltose and maltotriose. Preferred Composition: The fiber feedstock comprises less than 20 (preferably 0) wt.% starch. The amount of glucose in reaction product is greater than the amount of glucose obtained from reaction of fiber feedstock by greater than or equal to 100% (preferably greater than or equal to 10%). EXAMPLE - A mixture of fiber feedstock (250 mg) in 100 mM citrate buffer (5 ml) at pH 5.0; enzyme solution of 0.2 vol.% cellulase mix (including 0.2 vol.% GC-220(RTM: Genencor cellulase blend), 0.2 vol.% Celluclast L(RTM: Novozymes cellulase blend), and 0.1 vol.% Novozyme 28074(RTM: cellulase blend)); 0.2 vol.% hemicellulase mix (Ultraflo L(RTM: Novozymes hemicellulase blend)); and aspartic protease from Aspergillus saitoi having SEQ ID NO: 1 (Sequence not defined here may be found at ftp://ftp.wipo.int/pub/published_pct_sequences/publication) were placed in a shaker at 55 degrees C for 48 hours. Fiber feedstocks were prepared by grinding with a Wiley mill and sieving through a 40 mesh screen. Fiber feedstocks comprised corn fiber, corn stover, corn gluten feed, distillers'dried grains (DDG), distillers'dried grains with solubles (DDGS), switchgrass, soy hulls, wheat chaff and wheat straw. Samples of each reaction were spun, and supernatant was used for glucose analysis. An amount of available glucose was increased over the control (which did not include protease) by 130% for corn gluten feed, 79.4% for DDGS, 47.3% for soy hulls and 45.7% for DDG.
