    • The present invention relates to mutants of a parent Trichoderma strain, comprising a polynucleotide encoding a polypeptide and one or more (several) genes selected from the group consisting of a first subtilisin-like serine protease gene, a first aspartic protease gene, a trypsin-like serine protease gene, a second subtilisin-like serine protease gene, and a second aspartic protease gene, wherein the one or more (several) genes are modified rendering the mutant strain deficient in the production of one or more (several) enzymes selected from the group consisting of a first subtilisin-like serine protease, a first aspartic protease, a trypsin-like serine protease, a second subtilisin-like serine protease, and a second aspartic protease, respectively, compared to the parent Trichoderma strain when cultivated under identical conditions. The present invention also relates to methods of producing a polypeptide in such mutants and methods for producing such mutants.
    • 本发明涉及亲本木霉属菌株的突变体,其包含编码多肽的多核苷酸和选自以下的一种或多种(几种)基因:第一枯草杆菌蛋白酶 - 丝氨酸蛋白酶基因,第一天冬氨酸蛋白酶基因,胰蛋白酶样丝氨酸蛋白酶基因,第二枯草杆菌蛋白酶样丝氨酸蛋白酶基因和第二天冬氨酸蛋白酶基因,其中所述一个或多个(几个)基因被修饰使得所述突变体 选自第一枯草杆菌蛋白酶样丝氨酸蛋白酶,第一天冬氨酸蛋白酶,胰蛋白酶样丝氨酸蛋白酶,第二枯草杆菌蛋白酶样丝氨酸蛋白酶和第二枯草杆菌蛋白酶样丝氨酸蛋白酶的一种或多种(几种)酶产生缺陷的菌株 当在相同条件下培养时,与亲本木霉属菌株相比,它们分别与天冬氨酸蛋白酶相比。 本发明还涉及在这种突变体中生产多肽的方法和生产这种突变体的方法。
