Two actinomycete strains, CM9-9(T) and AK2-48, which produced straight rod-shaped, non-motile cells, were isolated from soils in Chiang Mai and Phuket provinces, respectively, Thailand. The morphological and chemotaxonomic characteristics of the isolates coincided with those of the genus Agromyces. Phylogenetic analysis using 16S rRNA gene sequences also indicated that the isolates were clearly separated from their closest relative, Agromyces aurantiacus YIM 21741(T), and should be classified in the genus Agromyces. Furthermore, a combination of DNA-DNA hybridization results and physiological and biochemical properties indicated that the isolates could be distinguished from all recognized members of the genus Agromyces. The isolates therefore represent a novel species, for which the name Agromyces tropicus sp. nov. is proposed. The type strain is CM9-9(T) (=JCM 15672(T) =BCC 34764(T)).
两株放线菌菌株 CM9-9(T) 和 AK2-48，分别从泰国清迈省和普吉省的土壤中分离得到，其细胞呈直杆状，不运动。这些分离株的形态和化学分类特征与链霉菌属相符。基于 16S rRNA 基因序列的系统发育分析也表明，这些分离株与它们最接近的亲缘种橙色链霉菌 YIM 21741(T) 明显分开，应归入链霉菌属。此外，DNA-DNA 杂交结果和生理生化特性的组合表明，这些分离株可与链霉菌属中所有已确认的成员区分开来。因此，这些分离株代表了一个新的种，建议将其命名为热带链霉菌（Agromyces tropicus）。其模式菌株为 CM9-9(T)（=JCM 15672(T)=BCC 34764(T)）。
