A bacterial strain (CCUG 44693T) was recovered during an industrial hygiene control. Phylogenetic analyses using the 16S rRNA gene sequence of the isolate indicated that it represents a new lineage in the alpha-1 subclass of the Proteobacteria, with the highest sequence similarity of 93.3% to the type strain of Muricoccus roseus. In the polyamine pattern spermidine was the predominant compound. The polar lipid profile consisted of the major lipids phosphatidyl ethanolamine, phosphatidyl dimethylethanolamine, phosphatidyl glycerol, phosphatidyl cholin and an unknown amino lipid. The major respiratory quinone was a ubiquinone Q-10 and the major whole cell fatty acids were 19:0 cyclo omega8c and 18:1 omega7c. The isolate also contained 18:1 2-OH and other fatty acids typical for members of the alpha-1 subclass of the Proteobacteria in addition to 10:0 2-OH in low amounts, not detected in members of closely related genera. The strain grew heterotrophically and strictly aerobically and formed red-colored colonies on tryptone soy agar. Bacteriochlorophyll a could not be detected by direct spectrophotometric analyses of aerobically grown cells. On the basis of the phylogenetic analyses, chemotaxonomic and biochemical characteristics, we propose that strain CCUG 44693T (CIP 108310T) represents a new genus of the alpha-1 subclass of the Proteobacteria for which we propose the name Rhodovarius lipocyclicus gen. nov. sp. nov.

Rhodovarius lipocyclicus gen。十一月 sp。nov。，Proteobacteria的alpha-1子类的新属。

在工业卫生控制过程中回收了细菌菌株（CCUG 44693T）。使用分离物的16S rRNA基因序列进行的系统发育分析表明，它代表了变形杆菌α-1亚类中的一个新谱系，与玫瑰墨菲球菌的菌株的最高序列相似性为93.3％。在多胺模式中，亚精胺是主要化合物。极性脂质谱由主要脂质磷脂酰乙醇胺，磷脂酰二甲基乙醇胺，磷脂酰甘油，磷脂酰胆碱和未知的氨基脂质组成。主要的呼吸醌是泛醌Q-10，主要的全细胞脂肪酸是19：0环omega8c和18：1 omega7c。该分离物除10:10外，还含有18：1 2-OH和其他变形杆菌α-1亚类成员的典型脂肪酸。0 2-羟基含量低，在密切相关的属中未检出。该菌株异养和严格需氧生长，并在胰蛋白p大豆琼脂上形成红色菌落。通过对需氧生长细胞的直接分光光度分析无法检测到细菌叶绿素a。根据系统发育分析，化学分类和生化特征，我们建议菌株CCUG 44693T（CIP 108310T）代表变形杆菌属alpha-1子类的新属，我们将其命名为Rhodovarius lipocyclicus gen。十一月 sp。十一月 通过对需氧生长细胞的直接分光光度分析无法检测到细菌叶绿素a。根据系统发育分析，化学分类和生化特征，我们建议菌株CCUG 44693T（CIP 108310T）代表变形杆菌属alpha-1子类的新属，我们将其命名为Rhodovarius lipocyclicus gen。十一月 sp。十一月 通过对需氧生长细胞的直接分光光度分析无法检测到细菌叶绿素a。根据系统发育分析，化学分类和生化特征，我们建议菌株CCUG 44693T（CIP 108310T）代表变形杆菌属alpha-1子类的新属，我们将其命名为Rhodovarius lipocyclicus gen。十一月 sp。十一月
