Evidence is presented to show that numerical taxonomy is of proven value both for the circumscription and identification of Streptomyces species. In addition, 252 representatives of numerically defined species and species-groups of this taxon were examined for 273 unit characters and the resultant data analysed using conventional statistics. Clustering was only marginally affected by the proximity coefficients used or by test error, estimated at 3.37%. The numerical classification obtained confirmed and extended the results of previous taxometric surveys, notably by showing that the Streptomyces albidoflavus species-group encompassed taxospecies corresponding to S. albidoflavus, Streptomyces anulatus and Streptomyces halstedii. Rapid enzyme tests based upon the fluorophores, 7-amino-4-methylcoumarin and 4-methylumbelliferone, provide useful data for streptomycete systematics. It can be concluded that the genus Streptomyces is currently well circumscribed and underspeciated.
有证据表明，数值分类法在链霉菌物种的界定和鉴定方面具有已被证实的价值。此外，对该分类单元中通过数值定义的252个物种和物种组的代表进行了273个单位性状的检测，并使用传统统计学方法对所得数据进行了分析。聚类仅受到所用接近系数或估计为3.37%的测试误差的轻微影响。所得的数值分类结果证实并扩展了先前分类调查的结果，特别是表明白黄链霉菌物种组包含了与白黄链霉菌、环链霉菌和霍尔斯特德链霉菌相对应的分类种。基于荧光团7-氨基-4-甲基香豆素和4-甲基伞形酮的快速酶测试为链霉菌系统学提供了有用的数据。可以得出结论，链霉菌属目前界定良好但物种描述不足。
