Production of extracellular endochitinase could be increased 5-fold in the mycoparasite fungus Trichoderma harzianum by using the cellulase promoter cbh1 of Trichoderma reesei, whereas the total endochitinase activity increased 10-fold. The cbh1 promoter was not expressed on glucose and sucrose in T. harzianum and was induced by sophorose and on cellulase-inducing medium. The endogenous endochitinase gene was expressed at a low basal level on glucose and sucrose. No specific induction by crab shell chitin or sophorose was observed.
通过使用里氏木霉的纤维素酶启动子 cbh1,可使生防真菌哈茨木霉的胞外内切几丁质酶产量增加 5 倍,而总内切几丁质酶活性增加 10 倍。在哈茨木霉中,cbh1 启动子在葡萄糖和蔗糖上不表达,而是被槐糖和纤维素诱导型培养基诱导表达。内源性内切几丁质酶基因在葡萄糖和蔗糖上的基础表达水平较低。未观察到壳聚糖或槐糖的特异性诱导。
