A Gram-staining-positive, aerobic and non-motile strain, 0704P10-1(T), was isolated from hydrothermal sediment of the Indian Ocean. Phylogenetic, phenotypic and chemotaxonomic data for the organism supported that it belonged to the genus Janibacter. Strain 0704P10-1(T) showed 97.2-98.7% 16S rRNA gene sequence similarities to the type strains of recognized members of the genus Janibacter. It contained meso-diaminopimelic acid as the diagnostic diamino acid in the cell wall. MK-8(H4) was the only menaquinone detected. The major fatty acids were iso-C16 : 0, C17 : 1ω8c and 10-methyl C17 : 0. Meanwhile, the results of DNA-DNA hybridization studies and other physiological and biochemical tests allowed the genotypic and phenotypic differentiation of strain 0704P10-1(T) from closely related species. Thus, strain 0704P10-1(T) represents a novel species of the genus Janibacter, for which the name Janibacter indicus sp. nov. is proposed. The type strain is 0704P10-1(T) ( = LMG 27493(T) = CGMCC 1.12511(T)).
一株革兰氏阳性、需氧、不运动的菌株 0704P10-1(T)，从印度洋热液沉积物中分离得到。该菌的系统发育、表型和化学分类数据表明，它属于詹尼菌属。菌株 0704P10-1(T)的 16S rRNA 基因序列与詹尼菌属中已鉴定的模式种的相似度为 97.2-98.7%。它的细胞壁中含有二氨基庚二酸作为特征性二氨基庚二酸。检测到的唯一menaquinone 是 MK-8(H4)。主要脂肪酸为 iso-C16:0、C17:1ω8c 和 10-甲基 C17:0。同时，DNA-DNA 杂交研究和其他生理生化试验的结果表明，菌株 0704P10-1(T)在基因型和表型上与亲缘关系较近的种有所区别。因此，菌株 0704P10-1(T)代表了詹尼菌属的一个新种，命名为印度詹尼菌（Janibacter indicus）sp. nov.。模式菌株为 0704P10-1(T)（ = LMG 27493(T) = CGMCC 1.12511(T)）。
