A motile, rod-shaped and yellow-coloured bacterium, designated strain SYSU D60001, was isolated from a desert soil sample. Cells were Gram-stain-negative, catalase-negative and oxidase-positive. The major cellular fatty acids were summed feature 8 (C ω7c and/or C ω6c) and C. The respiratory quinone was ubiquinone-10. The genomic DNA G+C content was 68%. The polar lipids detected were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, an unidentified phospholipid and five unidentified polar lipids. Phylogenetic analysis based on the 16S rRNA gene sequences revealed that strain SYSU D60001 represents a novel species of the genus Sphingosinicella, with closely related strains Sphingosinicella ginsenosidimutans BS1 (95.81%), Sphingomonas deserti GL-C-18 (95.75%) and Sphingosinicella humi QZX222 (95.18%). Data from polyphasic taxonomy study suggest that the isolate represents a novel species in the genus Sphingosinicella, for which the name Sphingosinicella terrae sp. nov. is proposed. The type strain of the proposed new taxon is SYSU D60001 (= DSM 104938 = KCTC 52780 = NBRC 112955). We also propose the reclassification of Sphingomonas deserti as Sphingosinicella deserti comb. nov.
一株运动、杆状和黄色的细菌，命名为 SYSU D60001 菌株，从沙漠土壤样本中分离得到。细胞革兰氏染色阴性，接触酶阴性，氧化酶阳性。主要细胞脂肪酸为总和特征 8（C ω7c 和/或 C ω6c）和 C. 呼吸醌为泛醌-10。基因组 DNA G+C 含量为 68%。检测到的极性脂为双磷脂酰甘油、磷脂酰胆碱、磷脂酰乙醇胺、磷脂酰甘油、一种未鉴定的磷脂和五种未鉴定的极性脂。基于 16S rRNA 基因序列的系统发育分析表明，SYSU D60001 株代表了 Sphingosinicella 属的一个新种，与密切相关的菌株 Sphingosinicella ginsenosidimutans BS1（95.81%）、 Sphingomonas deserti GL-C-18（95.75%）和 Sphingosinicella humi QZX222（95.18%）最为相似。多相分类学研究的数据表明，该分离株代表了 Sphingosinicella 属中的一个新种，因此提议将其命名为 Sphingosinicella terrae sp. nov.。提议的新分类群的模式菌株为 SYSU D60001（=DSM 104938=KCTC 52780=NBRC 112955）。我们还提议将 Sphingomonas deserti 重新分类为 Sphingosinicella deserti comb. nov.。
