^aAPCS: alkali pretreated corn stover; SPB: alkaline pretreated bagasse; SPCS: steam pretreated corn stover; SPSB: steam pretreated sweet sorghum bagasse; SPLP: steam pretreated lodgepole pine; RTILs-PWS: RTILs (1-ethyl-3-methylimidazolium acetate) pretreated wheat straw; SPRS: steam pretreated rice straw
^bThe improvement means the improvement in released glucose with xylanase addition compared to that without xylanase addition
^cThe improvement of 90.2% was measured after 8 h saccharification, which released 14 mM reducing sugar
^dThe improvement of 55.60% finally makes a 46.70% hydrolysis of cellulose
