A Gram-stain-negative, short rod-shaped strain, MDT2-1-1, was isolated from cryoconite samples collected from the Midui glacier in Tibet, China. It grew aerobically from 7 to 40 °C, within a pH range of 6.0-10.0, and in NaCl concentration of 0 to 1.0% (w/v). The pairwise 16S rRNA gene sequence similarity, average nucleotide identity and digital DNA-DNA hybridization values between strains MDT2-1-1 and Sabulicella rubraurantiaca SYSU D01096 were 99.4%, 89.7% and 38.9%, respectively. Considering the results from phylogeny, phenotypic and genotypic data, strain MDT2-1-1 (=CGMCC 1.11170 = NBRC 110485) was suggested to represent a novel species of the genus Sabulicella, for which the name Sabulicella glaciei sp. nov. is proposed. Furthermore, based on the phylogenomic analysis, it is recommended that Roseomonas rubea, Roseomonas ponticola and Roseomonas oleicola be reclassified as Neoroseomonas rubea comb. nov., Falsiroseomonas ponticola comb. nov. and Falsiroseomonas oleicola comb. nov., respectively. Considering the illegitimate status of the genera names Pararoseomonas and Pseudoroseomonas, the species within the genera Pararoseomonas and Pseudoroseomonas should be transferred to Muricoccus and Teichococcus, respectively. Therefore, we proposed the following new combinations: Muricoccus aeriglobus comb. nov., Muricoccus aerilatus comb. nov., Muricoccus harenae comb. nov., Muricoccus nepalensis comb. nov., Muricoccus pecuniae comb. nov., Muricoccus radiodurans comb. nov., Muricoccus vinaceus comb. nov., Teichococcus aerofrigidensis comb. nov., Teichococcus aerophilus comb. nov., Teichococcus aestuarii comb. nov., Teichococcus cervicalis comb. nov., Teichococcus coralli comb. nov., Teichococcus deserti comb. nov., Teichococcus globiformis comb. nov., Teichococcus hibiscisoli comb. nov., Teichococcus musae comb. nov., Teichococcus oryzae comb. nov., Teichococcus rhizosphaerae comb. nov., Teichococcus ruber comb. nov., Teichococcus suffuscus comb. nov., Teichococcus vastitatis comb. nov., and Teichococcus wenyumeiae comb. nov.
一株革兰氏阴性、短杆状菌株 MDT2-1-1 从中国西藏美堆冰川的冰碛样品中分离得到。它在有氧条件下生长，最适生长温度为 7-40°C，最适 pH 值为 6.0-10.0，最适 NaCl 浓度为 0-1.0%（w/v）。菌株 MDT2-1-1 与 Sabulicella rubraurantiaca SYSU D01096 的 16S rRNA 基因序列相似性、平均核苷酸同一性和数字 DNA-DNA 杂交值分别为 99.4%、89.7%和 38.9%。考虑到系统发育、表型和基因型数据，菌株 MDT2-1-1（=CGMCC 1.11170= NBRC 110485）被建议代表 Sabulicella 属的一个新种，命名为 Sabulicella glaciei sp. nov.。此外，基于系统基因组分析，建议将 Roseomonas rubea、Roseomonas ponticola 和 Roseomonas oleicola 重新分类为 Neoroseomonas rubea comb. nov.、Falsiroseomonas ponticola comb. nov. 和 Falsiroseomonas oleicola comb. nov.。考虑到 Pararoseomonas 和 Pseudoroseomonas 两个属名的不合法地位，应将 Pararoseomonas 和 Pseudoroseomonas 属内的种转移到 Muricoccus 和 Teichococcus 属中。因此，我们提出了以下新的组合：Muricoccus aeriglobus comb. nov.、Muricoccus aerilatus comb. nov.、Muricoccus harenae comb. nov.、Muricoccus nepalensis comb. nov.、Muricoccus pecuniae comb. nov.、Muricoccus radiodurans comb. nov.、Muricoccus vinaceus comb. nov.、Teichococcus aerofrigidensis comb. nov.、Teichococcus aerophilus comb. nov.、Teichococcus aestuarii comb. nov.、Teichococcus cervicalis comb. nov.、Teichococcus coralli comb. nov.、Teichococcus deserti comb. nov.、Teichococcus globiformis comb. nov.、Teichococcus hibiscisoli comb. nov.、Teichococcus musae comb. nov.、Teichococcus oryzae comb. nov.、Teichococcus rhizosphaerae comb. nov.、Teichococcus ruber comb. nov.、Teichococcus suffuscus comb. nov.、Teichococcus vastitatis comb. nov. 和 Teichococcus wenyumeiae comb. nov.。
