Abstract: The production of 2,3-butanediol was carried out from fermentation of xylose by Klebsiella oxytoca ZU-03, in which xylose was the main reducing sugar in hemicellulosic hydrolysate. Under optimized conditions: xylose mass concentration 90g/L, corn liquor mass concentration 6g/L, inoculum 10% (volume fraction), initial pH value 5.5 and 30℃, concentration of 2,3-butanediol reached 36.22g/L and yield of 2,3-butanediol from xylose was 0.45g/g.

Key words: 3-butanediol, xylose, hemicellulose, fermentation
