一个新属，Stella，是为一组扁平的、六叉的星形假丝杆菌提出的，这些细菌在遥远的地理区域的淡水、土壤和污水中发现。细胞的形态提供了与所有其他真细菌的明显区别。这些生物的细胞形态和繁殖方式也提供了与其他萌芽和附生的原细菌的明显分离。这些细胞革兰氏阴性，扁平，不活动，形成无孢子体。该属的代表性生物是化学有机营养，生长在低营养浓度下，并利用各种氨基酸和有机酸。识别出两个不同的种。模式种(Stella Humosa)是一种腐朽生物，模式菌株(菌株AUCM B-1137)已保存在苏联莫斯科的AUCM微生物馆藏和苏联莫斯科科学院微生物研究所。空泡链霉菌是一株气态空泡型原细菌，模式菌株为229菌株(苏联莫斯科科学院微生物研究所)。Stella属的生物体似乎代表了原核细胞中的第一个径向对称的例子。
A new genus, Stella, is proposed for a group of flat, six-pronged star-shaped prosthecobacteria found in freshwater, soil, and sewage in widely separated geographical areas. The morphology of the cells provides clear differentiation from all other eubacteria. The cellular morphology and mode of multiplication of these organisms also provide clear separation from other budding and appendaged prosthecobacteria. The cells are gram negative, flat, nonmotile, and asporogenic. Representative organisms in the genus are chemoorganotrophic, growing on low nutrient concentrations and utilizing a variety of amino acids and organic acids. Two distinct species are recognized. Stella humosa (type species) is an avacuolate organism, and the type strain (strain AUCM B-1137) has been deposited in the All Union Collection of Microorganisms, Moscow, USSR, and in the Institute of Microbiology, Academy of Sciences, Moscow, USSR. Stella vacuolata is a gas vacuolate prosthecobacterium, and the type strain is strain 229 (Institute of Microbiology, Academy of Sciences, Moscow, USSR). Organisms in the genus Stella appear to represent the first example of radial symmetry in procaryotic cells.
