Members of the genera Aurantimonas and Fulvimarina have largely been described on the basis of 16S rRNA gene sequence analyses, biochemical tests and limited chemotaxonomic data. Examination of the polar lipid compositions of members of these two genera indicated that although the patterns were similar with regards the phospholipid and amino lipid compositions, there were clear differences in the presence or absence of the glycolipid sulfoquinovosyldiacylglycerol (SQDG). This glycolipid was absent in members of the species Aurantimonas coralicida and Fulvimarina pelagi but was present in Aurantimonas altamirensis, Aurantimonas ureilytica and Aurantimonas frigidaquae. These results are also consistent with the 16S rRNA sequence-based grouping. We therefore propose that the genus Aurantimonas be divided further to reflect this additional information. Thus, it is recommended that Aurantimonas altamirensis, Aurantimonas ureilytica and Aurantimonas frigidaquae are transferred to a new genus, Aureimonas gen. nov., as Aureimonas altamirensis gen. nov., comb. nov. (type strain S21B(T) = CECT 7138(T) = CIP 109525(T) = KCTC 22106(T) = LMG 23375(T) = DSM 21988(T)), Aureimonas ureilytica comb. nov. (type strain 5715S-12(T) = KACC 11607(T) = DSM 18598(T) = CIP 109815(T)) and Aureimonas frigidaquae comb. nov. (type strain CW5(T) = KCTC 12893(T) = JCM 14755(T) = DSM 21987(T)). The type species of the new genus is Aureimonas altamirensis. Additionally, emended descriptions of the genera Aurantimonas and Fulvimarina are provided.
属 Aurantimonas 和 Fulvimarina 的成员主要是根据 16S rRNA 基因序列分析、生化测试和有限的化学生物分类数据来描述的。对这两个属成员的极性脂成分的研究表明，尽管磷脂和氨基酸脂成分的模式相似，但在糖脂 sulfoquinovosyldiacylglycerol (SQDG) 的存在与否方面存在明显差异。这种糖脂不存在于 Aurantimonas coralicida 和 Fulvimarina pelagi 的物种成员中，但存在于 Aurantimonas altamirensis、Aurantimonas ureilytica 和 Aurantimonas frigidaquae 中。这些结果也与基于 16S rRNA 序列的分组一致。因此，我们建议进一步划分 Aurantimonas 属以反映这些附加信息。因此，建议将 Aurantimonas altamirensis、Aurantimonas ureilytica 和 Aurantimonas frigidaquae 转移到一个新属 Aureimonas gen. nov.，即 Aureimonas altamirensis gen. nov.，组合新种（模式株 S21B(T) = CECT 7138(T) = CIP 109525(T) = KCTC 22106(T) = LMG 23375(T) = DSM 21988(T)）、Aureimonas ureilytica 组合新种（模式株 5715S-12(T) = KACC 11607(T) = DSM 18598(T) = CIP 109815(T)）和 Aureimonas frigidaquae 组合新种（模式株 CW5(T) = KCTC 12893(T) = JCM 14755(T) = DSM 21987(T)）。新属的模式种为 Aureimonas altamirensis。此外，还提供了 Aurantimonas 和 Fulvimarina 属的修订描述。
