摘要: 以里氏木霉(Trichodermareesei)RutC30为产酶菌,研究了不同碳氮比对木聚糖酶合成的影响。结果表明,低碳氮比有利于促进内切β木聚糖酶的合成,抑制外切β木糖苷酶的合成,有利于选择性合成低外切β木糖苷酶活的内切β木聚糖酶。高碳氮比使得木聚糖酶的合成滞后,能够有效地抑制纤维素酶的合成,提高木聚糖酶活与纤维素酶活的比值,有利于选择性合成低纤维素酶活的木聚糖酶。

Abstract: Effects of different ratios of carbon to nitrogen on xylanase synthesis by Trichoderma reesei Rut C-30 were studied.The results indicated that low ratio of carbon to nitrogen could stimulate the synthesis of endo-1,4-β-D xylanase and depress the synthesis of exo-β-xylosidase,which enhanced the synthesis of xylosidase poor xylanases.High ratio of carbon to nitrogen could not only retard the synthesis of xylanase,but also depress the synthesis of cellulase and increase the ratio of xylanase to cellulase,therefore enhanced the synthesis of cellulase poor xylanase.

Key words: Trichoderma reesei, xylanase, cellulase
