Insights into the capability of the lignocellulolytic enzymes of Penicillium parvum 4-14 to saccharify corn bran after alkaline hydrogen peroxide pretreatment

Table 1 The contents (%, w/w) of carbohydrates and lignin in corn bran before and after AHP pretreatment

Corn bran arabinoxylan (CBAX) 1 and 2 were extracted from destarched corn bran by AHP pretreatment and graded ethanol precipitation, as described in the “Methods” section. CBR, corn bran residue; A/X, ratio of arabinose to xylose; -, no analysis. The yield (%) indicates the weight ratio of the substrate to the raw material. The data represent the mean of three independent measurements
