对从印度洋深海富集的原油降解菌群中分离的菌株H32（T）进行了分类学研究。菌株H32（T）的16 S rRNA基因序列与Altererythrobacter luteolus SW-109（T）的16 S rRNA基因序列相似性最高。（96.7%）;与Altererythrobacter属其他成员的相似性较低（94.7- 95.7%）和红杆菌属（94.5- 96.3%）、赤微菌属（94.9%）和紫杆菌属（94.3- 95.3%）的成员。系统发育分析表明，H32（T）菌株属于交替红杆菌属（Altererythrobacter）。主要脂肪酸为C（16：0）（6.7%）、C（18：1）ω 7 c（44.3%）和11-甲基C（18：1）ω 7 c（25.4%）。主要呼吸醌是泛醌10。DNA G+C含量为66.5mol%。菌株H32（T）不含细菌叶绿素a。这些特征与Altererythrobacter属的成员非常一致。因此，根据其形态学、生理学、脂肪酸组成和16 S rRNA基因序列数据，菌株H32（T）属于Altererythrobacter属，但可以容易地与已知的Altererythrobacter种区分开。因此，提出菌株H32（T）代表一个新种，Altererythrobacter marinus sp. nov.，以H32（T）（=CCTCC AB 208229（T）=LMG 24629（T）=MCCC 1A 01070（T））为模式株。
A taxonomic study was carried out on strain H32(T), which was isolated from a crude-oil-degrading consortium enriched from deep seawater of the Indian Ocean. The 16S rRNA gene sequence of strain H32(T) showed highest similarity to that of Altererythrobacter luteolus SW-109(T) (96.7 %); lower similarities were observed with other members of the genus Altererythrobacter (94.7-95.7 %) and with members of the genera Erythrobacter (94.5-96.3 %), Erythromicrobium (94.9 %) and Porphyrobacter (94.3-95.3 %). Phylogenetic analyses of all members of the family Erythrobacteraceae and several members of the family Sphingomonadaceae revealed that strain H32(T) formed a clade within the genus Altererythrobacter. The dominant fatty acids were C(16 : 0) (6.7 %), C(18 : 1)omega7c (44.3 %) and 11-methyl C(18 : 1)omega7c (25.4 %). The major respiratory quinone was ubiquinone 10. The DNA G+C content was 66.5 mol%. Strain H32(T) did not contain bacteriochlorophyll a. These characteristics are in good agreement with those of members of the genus Altererythrobacter. Therefore, according to its morphology, physiology, fatty acid composition and 16S rRNA gene sequence data, strain H32(T) belongs to the genus Altererythrobacter, but can be readily distinguished from known Altererythrobacter species. It is therefore proposed that strain H32(T) represents a novel species, Altererythrobacter marinus sp. nov., with H32(T) (=CCTCC AB 208229(T) =LMG 24629(T) =MCCC 1A01070(T)) as the type strain.
