Title
Improved efficiency of butanol production by absorbed lignocellulose fermentation
Abstract

Alkali-treated steam-exploded corn stover (SECSAT) was used as solid substrate for acetone–butanol–ethanol (ABE) production by absorbed lignocellulose fermentation (ALF) using Clostridium acetobutylicum ATCC 824. The ABE concentration in ALF culture had increased by 47% compared with that in submerged culture. More surprisingly, the acetone production was promoted and ethanol production was lower in the presence of SECSAT than that in its absence. ALF was also successfully in cofermentation of glucose and xylose, although decreased fermentability with an increase in the proportion of xylose. An invariable chemical composition and dry weight of SECSAT was found in ALF. Partial simultaneous saccharification and fermentation of SECSAT using a certain amount of cellulase could not only enhance the ABE concentration by 71%, but also significantly increase the area proportion of fiber cells in SECSAT from 53% to 90%, which would be an excellent paper making material.

► Enhanced butanol production is achieved by absorbed lignocellulose fermentation. ► Absorbed lignocellulose fermentation is successful in effective cofermentation. ► Partial simultaneous saccharification and fermentation further enhance ABE yield. ► Partial saccharified absorbed lignocellulose is an excellent paper making material.
