Abstract

Hexose and pentose sugars, produced by hydrogen-fluoride solvolysis of aspen wood chips, were totally consumed in a coculture fermentation by Zymomonas mobilis and a mutant of Clostridium saccharolyticum. Z. mobilis converted the glucose to ethanol, while the mutant, which was improved in both ethanol production and tolerance, converted the xylose component to ethanol. A high conversion efficiency of wood sugars to ethanol was obtained, and the cells after the fermentation were successfully used for cell recycle.
