streptomyces 解釋
n. 名詞 （pl. streptomyces ） 【生物學】鏈絲菌屬 （Streptomyces） 菌。

  18. In this study, the avermectin - producing strain streptomyces avermitilis was studied and the avermectin biosynthesis gene cluster in the genomic dna of streptomyces avermitilis s - 2 was altered by the method of gene engineering. insertion inactivation of aved gene in the cluster by introducing apramycin resistance gene into aved gene resulted in the disappearance of " a " components of avermectins. when avec gene was inactivated by the same way, four " 1 " components were lost and only " 2 " components, the potential precursor of ivermectin, were accumulated
