A Gram-stain-negative, aerobic, short rod-shaped, non-motile bacterium (THG-S3), was isolated from desert soil. Growth occurred at 15-35 °C (optimum 28 °C), at pH 5-10 (optimum 7) and at 0-4 % NaCl (optimum 1 %). Based on 16S rRNA gene sequence analysis, the nearest phylogenetic neighbours of strain THG-S3 were identified as Altererythrobacter rigui KCTC 42620 (99.0 %), Altererythrobacter dongtanensis KCTC 22672 (97.1 %), Altererythrobacter xinjiangensis CCTCC AB 207166 (96.9 %), Altererythrobacter troitsensis KCTC 12303 (96.9 %). Levels of relatedness among strain THG-S3 and other Altererythrobacter species were lower than 96.0 %. DNA-DNA hybridization values between strain THG-S3 and A. rigui KCTC 42620, A. dongtanensis KCTC 22672, A. xinjiangensis CCTCC AB 207166 and A. troitsensis KCTC 12303 were 59.7 % (42.8 %, reciprocal analysis), 45.1 % (36.3 %), 34.7 % (25.1 %) and 15.1 % (12.3 %), respectively. The DNA G+C content of strain THG-S3 was 69 mol%. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and three unidentified lipids The quinone was ubiquinone-10. The major fatty acids were C16 : 0, C17 : 1 ω6c, C18 : 1 ω7c and summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c). On the basis of the phylogenetic analysis, chemotaxonomic data, physiological characteristics and DNA-DNA hybridization data, strain THG-S3 represents a novel species of the genus Altererythrobacter, for which the name Altererythrobacter deserti sp. nov. is proposed. The type strain is THG-S3 (=KACC 19190=CGMCC 1.15959).
一株革兰氏阴性、需氧、短杆状、非运动的细菌（THG-S3）从沙漠土壤中分离得到。该菌在 15-35°C（最佳温度 28°C）、pH 值 5-10（最佳 pH 值 7）和 0-4%NaCl（最佳 1%NaCl）条件下生长。根据 16S rRNA 基因序列分析，菌株 THG-S3 的最接近的系统发育同源物为 Rigui KCTC 42620（99.0%）、Dongtanensis KCTC 22672（97.1%）、Xinjiangensis CCTCC AB 207166（96.9%）和Troitsensis KCTC 12303（96.9%）。THG-S3 菌株与其他 Altererythrobacter 种之间的亲缘关系水平低于 96.0%。THG-S3 菌株与 Rigui KCTC 42620、Dongtanensis KCTC 22672、Xinjiangensis CCTCC AB 207166 和 Troitsensis KCTC 12303 的 DNA-DNA 杂交值分别为 59.7%（42.8%，反向分析）、45.1%、34.7%和 15.1%。THG-S3 菌株的 DNA G+C 含量为 69mol%。极性脂为双磷脂酰甘油、磷脂酰乙醇胺、磷脂酰甘油和三种未鉴定的脂类。醌类为泛醌-10。主要脂肪酸为 C16:0、C17:1 ω6c、C18:1 ω7c 和总和特征 3（C16:1 ω7c 和/或 C16:1 ω6c）。基于系统发育分析、化学分类学数据、生理特性和 DNA-DNA 杂交数据，菌株 THG-S3 代表 Altererythrobacter 属的一个新种，命名为 Altererythrobacter deserti sp. nov.。模式菌株为 THG-S3（=KACC 19190=CGMCC 1.15959）。
