Abstract

Hydrolyzates from hydrogen fluoride (HF) treated aspenwood were predominantly composed of oligosaccharides which are not readily utilized by Klebsiella pneumoniae. Attempts at further hydrolyzing these oligosaccharides using a variety of glycolytic and xylanolytic enzymes (i.e., amylases, cellulases, and xylanases) were only partially successful. When a post-hydrolysis step was carried out using 3% H2SO4, significant amounts of the component monosaccharides were detected. Sugars released by acid or enzymatic hydrolysis of the HF treated aspenwood were utilized by K. pneumoniae for the production of butanediol and ethanol.
