从云南丽江森林土壤样品中分离到一株革兰氏阳性短杆状细菌YIM 004（T），并对其进行了多相分类学研究。该分离株含有与其系统发育邻居Georgenia muralis对应的化学分类学标记，即它具有A4 alpha型肽聚糖，其中赖氨酸作为诊断细胞壁二氨基酸，主要的甲萘醌是MK-8（H-4），主要脂肪酸是ai-C-15：0。基因组DNA的G+C含量为72.9mol%。YIM 004（T）与G. muralis DSM 14418（T）根据分离物与G. YIM 004（T）菌株代表Georgenia属的一个新种，并建议将其命名为Georgenia ruanii sp. nov.。模式菌株为YIMI 004（T）（=CCTCC AB 204065（T）= DSM 17458（T）=KCTC 19029（T））。此外，还对Georgenia属植物作了订正描述。
A Gram-positive, motile, short-rod-shaped strain, designated YIM 004(T) was isolated from a forest-soil sample collected from Lijiang, Yunnan Province, China, and was investigated using a polyphasic taxonomic approach. The isolate contained chemotaxonomic markers that corresponded to those of its phylogenetic neighbour, Georgenia muralis, i.e. it possessed pepticloglycan type A4 alpha with lysine as the diagnostic cell-wall diamino acid, the predominant menaquinone was MK-8(H-4) and the major fatty acid was ai-C-15:0. The G+C content of the genomic DNA was 72.9 mol%. Strain YIM 004(T) exhibited a 1 6S rRNA gene sequence similarity of 97.3 % and a DNA-DNA relatedness value of 18 % with respect to G. muralis DSM 14418(T) On the basis of the phenotypic and genotypic differences between the isolate and G. muralis, strain YIM 004(T) represents a novel species of the genus Georgenia, for which the name Georgenia ruanii sp. nov. is proposed. The type strain is YIMI 004(T) (=CCTCC AB 204065(T) = DSM 17458(T) =KCTC 19029(T)). In addition, an emended description of the genus Georgenia is presented.
