Rice straw pretreated with liquid anhydrous ammonia was hydrolyzed with cellulase, cellobiase, and hemicellulase. Ammonia-processing
conditions were 1.5 g of NH3/g of dry matter, 85°C, and several sample moisture contents. There were four ammonia addition time (min)-processing time
(min) combinations. Sugars produced were analyzed as reducing sugars (dinitrosalicylic acid method) and by high-performance
liquid chromatography. Monomeric sugars increased from 11% in the nontreated rice straw to 61% of theoretical in treated rice
straw (79.2% conversion as reducing sugars). Production of monosaccharides was greater at higher moisture content and was
processing time dependent. Glucose was the monosaccharide produced in greater amounts, 56.0%, followed by xylose, arabinose,
and fructose, with 35.8, 6.6, and 1.4%, respectively. 相似文献
