在一项多相研究中，确定了暂时归属无枝酸菌属的七种土壤放线菌的分类地位。这些分离株具有相同的 16S rRNA 基因序列，与东方拟无枝酸菌的模式菌株最相似。代表性分离菌株 GY080T 具有无枝酸菌属的典型化学分类学特性，并且可以使用 DNA-DNA 相关性数据将其与东方拟酸菌的典型菌株区分开来。所有分离株都有一个表型特征，将它们与系统发育密切相关的物种的代表区分开来。扩增的 rDNA 限制性分析表明，分离物形成了一个同质组，该组与由代表性无枝酸菌型菌株（包括东方无枝酸菌菌株）组成的单成员组明显不同。基于综合的基因型和表型证据，建议将这七个分离株归类为新物种的代表，该新物种的名称为 Amycolatopsis regifaucium sp。十一月被提议。类型菌株是 GY080T (=DSM 45072T=NCIMB 14277T)。
The taxonomic position of seven soil actinomycetes provisionally assigned to the genus Amycolatopsis was established in a polyphasic study. The isolates, which had identical 16S rRNA gene sequences, had closest similarity to the type strain of Amycolatopsis orientalis. A representative isolate, strain GY080T, had chemotaxonomic properties that were typical of the genus Amycolatopsis and could be distinguished from the type strain of A. orientalis using DNA-DNA relatedness data. All of the isolates shared a phenotypic profile that distinguished them from representatives of phylogenetically closely related species. Amplified rDNA restriction analysis showed that the isolates formed a homogeneous group that was distinctly separate from single-membered groups consisting of representative Amycolatopsis type strains, including that of A. orientalis. Based on the combined genotypic and phenotypic evidence, it is proposed that the seven isolates be classified as representatives of a novel species for which the name Amycolatopsis regifaucium sp. nov. is proposed. The type strain is GY080T (=DSM 45072T=NCIMB 14277T).
