The taxonomic position of an unknown actinomycete isolated from a sand dune soil sample collected at Borg El-Arab in Egypt was established using a combination of genotypic and phenotypic data. Isolate S136(T) had chemotaxonomic and morphological properties consistent with its classification in the genus Nonomuraea and formed a distinct phyletic line in the Nonomuraea 16S rRNA gene tree. It was most closely related to the type strains of Nonomuraea helvata, Nonomuraea kuesteri and Nonomuraea turkmeniaca, sharing 16S rRNA gene similarities with these species of 97.1, 97.2 and 97.3%, respectively. The organism was distinguished from representatives of validly described Nonomuraea species using a range of phenotypic properties. It is apparent that the isolate belongs to a novel Nonomuraea species. The name proposed for this taxon is Nonomuraea aegyptia sp. nov., the type strain is S136(T) (=CGMCC 4.2054(T) = DSM 45082(T)).
利用基因型和表型数据相结合的方法，确定了从埃及布尔格·阿拉伯采集的沙丘土壤样本中分离出的一种未知放线菌的分类地位。分离株S136(T)具有化学分类学和形态学特性，与其在野野村菌属中的分类一致，并且在野野村菌属16S rRNA基因树中形成了一个独特的进化分支。它与淡黄野野村菌、库斯特野野村菌和土库曼野野村菌的模式菌株关系最为密切，与这些物种的16S rRNA基因相似性分别为97.1%、97.2%和97.3%。利用一系列表型特性将该菌株与已有效描述的野野村菌属物种的代表区分开来。显然，该分离株属于一个新的野野村菌物种。为这个分类单元提议的名称是埃及野野村菌（Nonomuraea aegyptia sp. nov.），模式菌株是S136(T)（=CGMCC 4.2054(T)=DSM 45082(T)）。
