Procedure

Combined hydrolysis and fermentation of hemicelluloses for the direct production of fuels and chemicals: Xylanase enzyme preparations from 1 can be used in conjunction with fermentative organisms to simultaneously hydrolyze hemicellulose to sugars and ferment the sugars released to a variety of fuels and chemicals. An example of this is the use of Klebisella pneumoniae (Klebsiella oxytoca ATCC 8724) with the enzyme preparation to produce 2,3-butanediol, ethanol, acetoin, and acetic acid from xylan and steamexploded aspenwood hemicellulose (Table 7).
