Abstract

Corn stover, hemp woody core and tobacco stalk were treated by dilute ammonium hydroxide soaking for improving the enzymatic saccharification of cellulose and xylan to monosaccharides by commercial cellulase mixtures. As more lignin removal by dilute ammonium hydroxide impregnation led to more enzymatic saccaharification of cellulose and xylan to monosaccharides (corn stover vs tobacco stalk). There was no relationship between xylan removal by dilute ammonium hydroxide impregnation and enzymatic saccharification of polysaccharides in pretreated samples. Except corn stover, lower temperature and longer treatment ($50^{\circ}C$-6 day) was less lignin removal than higher temperature and shorter treatment ($90^{\circ}C$ 16 h). Corn stover showed the highest enzymatic saccharification of cellulose and xylan but tobacco stalk showed the lowest.
