化能有机营养型，好氧，兼性厌氧，非能动菌株MWH-C5 T分离寡-中营养型蒙兹湖（奥地利）的水柱的表型，遗传学，和化学分类学的特点。该菌株的主要脂肪酸为C16：1ω 7 c/ω6c、C16：0、C12：1和C8：0-3OH，主要醌为泛醌Q-8，DNA的G+C含量为55.5mol%。16 S rRNA基因与模式种的相似性分别为96.6%（纤细弯杆菌）和95.7%（发酵红ferax fermentans）。16 S rRNA基因序列的系统发育分析揭示了该菌株与丛枝单胞菌科（Betaproteobacteria）的隶属关系，然而，所揭示的菌株的系统发育位置并不表明隶属于该家族内任何先前描述的属。全家系性状比较表明，该菌株具有独特的G+C值，主要脂肪酸和主要3-羟基脂肪酸的组合。此外，该菌株在几个性状上与最接近的属不同。根据该菌株的亲缘关系以及与最近亲缘属的差异，我们建议将该菌株建立为Limnohabitans gen. nov.，并将该菌株归入新种Limnohabitans curvus sp. nov.，模式菌株MWH-C5 T（DSM 21645 T，= CCUG 56720 T）。该模式菌株与各种淡水系统中通过非培养方法检测到的大量未培养细菌密切相关。
The chemoorganotrophic, aerobic, facultatively anaerobic, non-motile strain MWH-C5T isolated from the water column of oligo-mesotrophic Lake Mondsee (Austria) was phenotypically, phylogenetically, and chemotaxonomically characterized. The predominant fatty acids of the strain were C16:1ω7c/ω6c, C16:0, C12:1, and C8:0-3OH, the major quinone was ubiquinone Q-8, and the G+C content of the DNA of the strain was 55.5 mol%. The 16S rRNA gene similarity to the closest related type species were 96.6% (Curvibacter delicatus) and 95.7% (Rhodoferax fermentans). The phylogenetic analysis of the 16S rRNA gene sequences revealed the affiliation of the strain with the family Comamonadaceae (Betaproteobacteria), however, the revealed phylogenetic position of the strain did not indicate the affiliation to any previously described genus within this family. A family-wide comparison of traits revealed that the strain possesses a unique combination of G+C value, major fatty acids, and major 3-hydroxy fatty acid. Furthermore, the strain differs in several traits from the closest related genera. Based on the phylogeny of the strain and the differences to the closest related genera, we propose to establish the genus Limnohabitans gen. nov. to accommodate this strain, and to place the strain in the new species Limnohabitans curvus sp. nov., with the type strain MWH-C5T (DSM 21645T, = CCUG 56720 T). The type strain is closely related to a large number of uncultured bacteria detected by cultivation-independent methods in various freshwater systems.
