超声波辅助不同碱预处理对甘蔗渣酶解生成木糖含量的影响

摘要

超声波辅助NaOH,KOH,Ca(OH)2和氨水4种单碱和混合双碱预处理酶解甘蔗渣,以水解液中木糖浓度为参考指标,比较不同预处理的效果.实验结果表明超声波辅助NaOH/氨水效果最佳,木糖浓度达1.928 g/L.%Ultrasonic-assisted NaOH,KOH,Ca(OH)2 and ammonium hydroxide are used to digest bagasse.The concentration of xylose in the hydrolyzate is used as a reference index to compare the effects of different pretreatments.The experimental results show that ultrasonic assisted NaOH/ammonium hydroxide has the best effect,xylose concentration is 1.928 g/L.
