摘要
对链孢囊菌属的28株放线菌和4株气丝可形成孢囊的放线菌进行了形态、生理生化特性、生长条件、抗生素敏感性、抗菌谱等107项试验测定。根据Ssm相似性系数及平均链锁聚类方式,借助于电子计算机对这些菌株进行了比较。结果表明,11株国际公认的链孢囊菌属的标准菌和一株已知的链孢囊菌与供试未知菌,在59％的水平上归为一群。通过数值分类把所比较的菌株在77％水平上区分为不同的表观群,为进一步的分子分类学研究和种的鉴定提供了依据。
35 strains in sporangia-forming Actnomycetes were compared with numerical classification using 107 characters. There are 11 type strains and 17 unknown strains belong to Streptosporangium, and 3 strains of Kutzneria and 4 strains related Actinomycetes. Data were examined using the average linkage clustering (UPGMA). The result by Ssm coefficient showed that nine clusters and four alone strains were obtained at 77% similarity level in dendrogram. Clustering was made the UPGMA analysis with computer TRS.
