Abstract Seven strains of five species of the genus Ectothiorhodospira were characterized by oligonucleotide cataloguing of their 16S rRNA in order to determine the phylogenetic relationship to one another and to other phototrophic purple bacteria. All representatives of Ectothiorhodospira are members of that line of descent defined by phototrophic purple sulfur bacteria and relatives, showing a moderate relationship to those phototrophic organisms forming globules of elemental sulfur inside the cell (Chromatium and relatives). The 5 Ectothiorhodospira species fall into two subgroups. E.halophila, E. halochloris and E. abdelmalekii form one, E. mobilis, E. shaposhnikovii and the unnamed strain BN 9906 form the second subgroup. Within the two subgroups the strains are closely related, while the degree of relatedness found between members of the two subgroups is more distant.
