Frontiers | Effect of the Combining Corn Steep Liquor and Urea Pre ...
A novel pretreatment using corn steep liquor (CSL) and urea was developed to enhance the enzymatic saccharification and degradability of rice straw (RS). We used RS (1) without (Con) or with additives of (2) 5% urea (U), (3) 9% CSL and % urea (CU), and (4) 9% CSL and 5% urea (C5U). The result showed that the watersoluble carbohydrate (WSC) conversion of RS reached % after C5U pre ...
