对从日本不同医院分离的两种细菌菌株进行多相分析。发现新型萜类抗生素生产菌IFM 0406和IFM 0706（T）具有与它们在诺卡氏菌属中的分类一致的形态学、生物化学、生理学和化学分类学特性，除了存在MK-8（H-4）作为除主要甲基萘醌MK-8（H4 omega-cyc）之外的主要甲基萘醌之一。IFM 0406和IFM 0706（T）的16 S rRNA基因序列相似性为99.9%，与这两株诺卡氏菌最接近的成员为模式株Nocardia nova和Nocardia mexicana，相似性分别为97.5%和97.1%。根据其特征表型和系统发育特性，提出这两株菌为诺卡氏菌属的一个新种--萜烯诺卡氏菌（Nocardia terpenica sp. nov.）。模式菌株是IFM 0706（T）（= JCM 13033（T）= DSM 44935（T）= NBRC 100888（T））。
Two bacterial strains isolated from different hospitals in Japan were subjected to a polyphasic analysis. Strains IFM 0406 and IFM 0706(T), producers of novel terpenoid antibiotics, were found to have morphological, biochemical, physiological and chermotaxonomic properties consistent with their classification in the genus Nocardia, except for the presence of MK-8(H-4) as one of the predominant menaquinones in addition to the major menaquinone MK-8(H4 omega-cyc). The 16S rRNA gene sequence similarity of strains IFM 0406 and IFM 0706(T) was 99.9 %, and the closest members of Nocardia to these strains were the type strains of Nocardia nova and Nocardia mexicana, showing similarity of 97.5 and 97.1 %, respectively. Based on their characteristic phenotypic and phylogenetic properties, a novel species of the genus Nocardia, Nocardia terpenica sp. nov. is proposed for the two strains. The type strain is IFM 0706(T) (= JCM 13033(T) = DSM 44935(T) = NBRC 100888(T)).
