During the course of isolating and identifying purple non-sulfur bacteria, one nitrate-reducing strain was isolated which did not fit the description of any other purple non-sulfur bacterium known to date. The isolate had rod-shaped cells that contained lamellar intracytoplasmic membranes and produced red cultures. Absorption maxima of photosynthetically grown cell homogenates were at 376, 471, 503, 540, 591, 805 and 878 nm. The new isolate grew anaerobically in the light or aerobically in the dark. Various organic compounds served as carbon sources and electron donors. The predominant quinone was ubiquinone 10, the predominant fatty acid was 18:1omega7c. The polar lipids comprised diphosphatidyl glycerol, phosphatidyl glycerol, phosphatidyl ethanolamine and phosphatidyl choline. Analysis of the 16S rDNA gene sequences revealed that the new isolate was closely related to Rhodopseudomonas palustris. A DNA-DNA- hybridization study differentiated the new isolate and Rhodopseudomonas palustris at the species level. Therefore, the name Rhodopseudomonas rhenobacensis sp. nov. is proposed for the new isolate.
在分离和鉴定紫色非硫细菌的过程中，分离出了一株硝酸盐还原菌株，它不符合迄今已知的任何其他紫色非硫细菌的描述。该分离株具有杆状细胞，含有层状胞内膜，并产生红色菌落。光合生长的细胞匀浆的吸收峰分别位于376、471、503、540、591、805和878nm处。新分离株在光照下厌氧生长，在黑暗中需氧生长。各种有机化合物可作为碳源和电子供体。主要醌为泛醌10，主要脂肪酸为18:1ω7c。极性脂类包括双磷脂酰甘油、磷脂酰甘油、磷脂酰乙醇胺和磷脂酰胆碱。对16S rDNA基因序列的分析表明，新分离株与沼泽红假单胞菌密切相关。DNA-DNA杂交研究在种水平上区分了新分离株和沼泽红假单胞菌。因此，提议将新分离株命名为莱茵河红假单胞菌（Rhodopseudomonas rhenobacensis sp. nov.）。
