Most of the soy hull hydrolyses were done using cellulase, hemi- cellulase and pectinase provided by Novozymes. Preliminary screening experiments showed that a mix- ture containing equal volumes of three specific enzymes was most effective and produced the highest conversion of SBH to soluble carbohydrates. The temperature and pH optima for these enzymes ranged from 40 to 50 C and 5-5.5, respectively. Limited trials with similar mixtures of cellulase, hemicellulase and pectinase (Multifect CX-GC, Multifect CX-2000L, Multifect CX-B and Multi- fect Pectinex FE) from Genencor produced approximately the same degree of hydrolysis. In experiments where SBH was pre-treated with enzymes, hydrolysis was done at 50 oC and pH 5 in 100mM acetate buffer (Buffer A).
