| 摘 要： | 本文对产纤维素酶的木霉菌孢子和斜面培养菌体搭载中国第18颗返回式卫星后,菌落形态和产酶能力的变化进行了研究。实验结果表明,搭载菌株的菌落形态发生变异,菌株的生长周期出现了缩短或延长的现象。对搭载的木霉菌株进行筛选,获得3株产酶能力大幅度提高的优良突变菌株,产酶能力提高了50%以上,且性状遗传稳定。 |
| 关 键 词： | 纤维素酶 木霉菌 空间诱变 |

| Abstract: | The slant mycelia cultured with or without mutagenic agent diethyl sulfate(DS) and spores of Trichoderma reesei were loaded in the 18~(th) returning satellite. Systematical screening showed that the life cycle and morphology of some strains had changed after space flight. After selection and domestication, 3 mutant strains with high cellulose enzyme activity were isolated. The cellulose enzyme productivities of the mutants were significantly increased more than 50%, and the mutant were generically stable. |
| Keywords: | cellulose enzyme Trichoderma reesei space-induced mutant |
