- Abstract:
-
Several processes of saccharification based on steam-exploded corn stalk were compared in this pa-per,and the best process of saccharification is ; adding 1/3 cellulase firstly,adding 1/3 cellulase after 24 h,then adding the rest of the cellulase after 12 h,and saccharification 48 h in all.On this basis,the better con-ditions of fermentative process were investigated by single-factor experiment and orthogonal test. Under the op-timum conditions,the concentration of butanol can reach 9.42 g/L.
