A novel alkaliphilic, halotolerant, rod-shaped bacterium, designated strain YIM CH208(T), was isolated from a soda lake in Yunnan, south-west China. The taxonomy of strain YIM CH208(T) was investigated by a polyphasic approach. Strain YIM CH208(T) was Gram-negative, strictly aerobic and non-motile and formed red colonies. Optimal growth conditions were 28°C, pH8.5 and 0.5-2.5 % NaCl. Phylogenetic analysis based on 16S rRNA gene sequence comparisons showed that the isolate formed a distinct line within a clade containing the genus Echinicola in the phylum Bacteroidetes and was related to the species Echinicola pacifica and Rhodonellum psychrophilum, with sequence similarity of 91.7 and 91.6 % to the respective type strains. The DNA G+C content was 45.1 mol%. The major respiratory quinone was menaquinone-7 (MK-7). The predominant cellular fatty acids were iso-C(17 : 1)ω9c (19.9 %), C(15 : 0) 3-OH (12.1 %), iso-C(17 : 0) 3-OH (11.3 %), summed feature 3 (iso-C(15 : 0) 2-OH and/or C(16 : 1)ω7c; 10.7 %) and C(17 : 1)ω6c (8.7 %). On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain YIM CH208(T) represents a novel species of a new genus, for which the name Litoribacter ruber gen. nov., sp. nov. is proposed. The type strain of Litoribacter ruber is YIM CH208(T) (=ACCC 05414(T) =KCTC 22899(T)).
一株从中国西南部云南苏打湖分离得到的新型嗜碱、耐盐、杆状细菌，被命名为 YIM CH208(T) 菌株。通过多相分类法研究了 YIM CH208(T) 菌株的分类学。YIM CH208(T) 菌株为革兰氏阴性、严格需氧、非运动性，形成红色菌落。最佳生长条件为 28°C、pH8.5 和 0.5-2.5%NaCl。基于 16S rRNA 基因序列比较的系统发育分析表明，该分离株在厚壁菌门的 Echinicola 属中形成了一个独特的分支，与 Echinicola pacifica 和 Rhodonellum psychrophilum 种最为相关，与各自的模式株的序列相似性为 91.7%和 91.6%。DNA G+C 含量为 45.1 mol%。主要呼吸醌为menaquinone-7 (MK-7)。主要细胞脂肪酸为 iso-C(17 : 1)ω9c (19.9 %)、C(15 : 0) 3-OH (12.1 %)、iso-C(17 : 0) 3-OH (11.3 %)、summed feature 3 (iso-C(15 : 0) 2-OH 和/或 C(16 : 1)ω7c；10.7%)和 C(17 : 1)ω6c (8.7%)。基于表型、化学分类和系统发育数据，YIM CH208(T) 菌株代表了一个新属的新种，建议将其命名为 Litoribacter ruber 属，nov. 种。Litoribacter ruber 的模式菌株为 YIM CH208(T)=ACCC 05414(T)=KCTC 22899(T)。
