| 摘 要： | 从太空酒曲中分离、选育出主要功能菌：根霉SKR3、黑曲霉SKA2、米曲霉SKO3；与原生产中使用的曲药的主要功能菌-根霉SNR1、黑曲霉SNA4、米曲霉SNO2的酶活性进行比较研究。结果表明：SKR3的糖化酶、液化酶活性均比SNR1高出两倍以上，SKR3培养36h后其糖化酶、液化酶活性达到SNR1培养72h后的两倍；SKA2的糖化酶、液化酶活性比SNA4的高出三倍，蛋白酶活性高出一至二倍，SKA2培养48h后糖化酶、液化酶活性达到SNA4培养72h的三倍；SKO3与SNO1的糖化酶、液化酶、蛋白酶活性基本无差异。

| Abstract: | The functional strains of Tai Kong Jiu Qu: SKR3(Rhizopus oryzae),SKA2(Aspergillus niger) and SKO3(Aspergillus oryzae) were separated and screened. The functional strains of Jiu Qu applied in production: SNR1(Rhizopus oryzae),SNA4(Aspergillus niger) and SNO2(Aspergillus oryzae) were separated. Enzyme activity were compared between SKR3 and SNR1,SKA2 and SNA4,SKO3 and SNO2. The results indicated that glucomylase's activity and (-mylase's activity of SKR3 were two times than that of SNR1. glucomylase's activity and (-mylase's activity of SKA2 were three times than that of SNA4. Protease's activity of SKA2 was one to two times than that of SNA4. There was not much difference between SKO3's and SNO1's enzyme activity. |
