摘　　要：对低聚木糖生产用里氏木霉木聚糖酶选择性合成的研究现状进行了较全面的总结和评述。系统地介绍了里氏木霉木聚糖酶的的多样性以及碳源、pH和碳氮比等培养条件对合成内切木聚糖酶和木糖苷酶的影响,提出了调控这些培养条件选择性合成低木糖苷酶活的木聚糖酶的方法。The present situation of research on selective biosynthesis of Trichoderma reesei xylanases for xyloohgosaccharides production is reviewed in detail. The multiplicity of Trichoderma reesei xylanase, and the effects of carbon source, pH value and ratio of carbon to nitrogen on synthesis of endo-xylanase and xylosidase are systematically reviewed, and the methods to controll these cultivation conditions to synthesize xylosidase-poor xylanases are put forward in order to make the xylanases better application in xylo-ohgosaccharides production.
