A Gram-positive, aerobic, non-motile, mesophilic strain, designated YIM 45721T, was isolated from a rhizosphere soil sample in Yunnan Province, China. On the basis of 16S rRNA gene sequence similarity analysis, strain YIM 45721T was assigned to the genus Microlunatus and was most closely related to the type strain of Microlunatus phosphovorus (98.2 % 16S rRNA gene sequence similarity). Chemotaxonomic data, including cell-wall peptidoglycan structure, menaquinones and fatty acid profile, supported affiliation of strain YIM 45721T to the genus Microlunatus. Results of DNA-DNA hybridization and physiological and biochemical tests enabled strain YIM 45721T to be differentiated genotypically and phenotypically from M. phosphovorus. Therefore, strain YIM 45721T represents a novel species of the genus Microlunatus, for which the name Microlunatus aurantiacus sp. nov. is proposed. The type strain is YIM 45721T (=CCTCC AB 206067T=DSM 18424T).
从中国云南省的根际土壤样品中分离出一株革兰氏阳性、需氧、不运动、嗜温的菌株，命名为YIM 45721T。基于16S rRNA基因序列相似性分析，菌株YIM 45721T被归入微小微菌属，与磷酸微小微菌模式菌株关系最为密切（16S rRNA基因序列相似性为98.2%）。包括细胞壁肽聚糖结构、甲基萘醌和脂肪酸谱在内的化学分类学数据支持菌株YIM 45721T属于微小微菌属。DNA-DNA杂交以及生理生化测试结果表明，菌株YIM 45721T在基因型和表型上与磷酸微小微菌不同。因此，菌株YIM 45721T代表微小微菌属的一个新物种，为此提出新名称橙色微小微菌（Microlunatus aurantiacus sp. nov.）。模式菌株为YIM 45721T（=CCTCC AB 206067T=DSM 18424T）。
