The genus Rhodospirillum is represented by four species, with three of them showing phylogenetic divergence compared to the type species, Rhodospirillum rubrum. Differences in the major diagnostic properties such as internal photosynthetic membranes, quinones, fatty acids, carotenoid composition and a few other phenotypic properties warrant the reclassification of members of this genus. Resultantly, a new genus, Pararhodospirillum gen. nov., is proposed based on the analysis of nine strains to accommodate Rhodospirillum photometricum, Rhodospirillum sulfurexigens and Rhodospirillum oryzae as Pararhodospirillum photometricum comb. nov., Pararhodospirillum sulfurexigens comb. nov. and Pararhodospirillum oryzae comb. nov., respectively. The type species of the genus is Pararhodospirillum photometricum comb. nov. An emended description of the genus Rhodospirillum is also proposed.
红螺菌属由四个种组成，其中三个种与模式种红色硫螺菌在系统发育上有明显差异。内部光合膜、醌类、脂肪酸、类胡萝卜素组成和其他一些表型特征的主要诊断特性的差异证明了该属成员需要重新分类。因此，基于对 9 株菌的分析，提出了一个新属，即副红螺菌属，以容纳光养红螺菌、硫化叶菌红螺菌和水稻红螺菌作为副红螺菌光养型组合新种、副红螺菌硫化叶菌组合新种和副红螺菌水稻型组合新种。该属的模式种是副红螺菌光养型组合新种。还提出了红螺菌属的修订描述。
