Following phylogenetic analysis based on 16S rRNA gene sequences, together with DNA G+C contents and differential chemotaxonomic and physiological characteristics, a new genus with the name Aliiglaciecola gen. nov. is proposed to more appropriately accommodate two recognized species of the genera Glaciecola and Aestuariibacter. Accordingly, [Glaciecola] lipolytica and [Aestuariibacter] litoralis should be reassigned to the novel genus as Aliiglaciecola lipolytica comb. nov. (type strain, E3(T) = JCM 15139(T) = CGMCC 1.7001(T)) and Aliiglaciecola litoralis comb. nov. (type strain, KMM 3894(T) = JCM 15896(T) = NRIC 0754(T)), respectively. Aliiglaciecola lipolytica is proposed as the type species of this new genus. Physiologically, the combined characteristics of positive reactions for nitrate reduction and growth at 4 °C and 36 °C distinguish the new genus from the genera Aestuariibacter and Glaciecola by one to three traits. Moreover, the new genus is also distinguished from the genus Glaciecola by the fatty acid profile and distinguished from the genus Aestuariibacter by the differences of major isoprenoid quinone (MK-7 vs Q-8) and DNA G+C content (40.8-43.0 mol% vs 48.0-54.0 mol%).
基于 16S rRNA 基因序列的系统发育分析,结合 DNA G+C 含量以及差异化学分类学和生理特性,提出了一个新属,名为 Aliiglaciecola 属,以更恰当地容纳两个已被认可的 Glaciecola 和 Aestuariibacter 属的种。因此,[Glaciecola] lipolytica 和 [Aestuariibacter] litoralis 应被重新分配到这个新属中,分别为 Aliiglaciecola lipolytica comb. nov.(模式株,E3(T) = JCM 15139(T) = CGMCC 1.7001(T))和 Aliiglaciecola litoralis comb. nov.(模式株,KMM 3894(T) = JCM 15896(T) = NRIC 0754(T))。Aliiglaciecola lipolytica 被提议为这个新属的模式种。从生理学上看,硝酸盐还原和在 4°C 和 36°C 下生长的阳性反应的综合特征,使新属与 Aestuariibacter 和 Glaciecola 属通过一个到三个特征区分开来。此外,新属还通过脂肪酸图谱与 Glaciecola 属区分开来,通过主要类异戊二烯醌(MK-7 与 Q-8)和 DNA G+C 含量(40.8-43.0 mol% 与 48.0-54.0 mol%)与 Aestuariibacter 属区分开来。
