摘　　要：由于木质纤维素的酸水解条件剧烈,水解液中必定存在影响微生物生长和发酵的物质,特别是多酚类化合物,需对水解液进行脱毒处理。通过探讨8种脱毒方法对还原糖损失率和酚类脱出率的影响,研究发现,树脂XDA-1+CaCO3,脱除酚类效果最好,还原糖损失率较低,并通过生物性检验也表现了良好的效果。As acid hydrolysis of lignocellulose was violent,the hydrolysates containes some compounds such as polyphenol which retarded the growth and fermentation of microorganisms.Therefore detoxification was needed.Eight kinds of detoxification methods were developed to study on xylose loss rate and the extrusion rate of phenols.The results showed that resin XDA-1＋CaCO3 was the best method for higher removal rate and lower xylose loss rate,and biological tests also showed good results.
