Abstract Blastobacter aggregatus and a Blastobacter-like isolate (IFAM 1031) were analysed by the 16S ribosomal RNA cataloguing approach in order to determine their phylogenetic position. Both phenotypical similar organisms are members of the alpha-subdivision of purple phototrophic bacteria and their non-phototrophic relatives but they are not closely related: B. aggregatus clusters with Agrobacterium tumefaciens and Rhizobium species; the unnamed strain displays a moderate relationship to members of Rhodobacter and Paracoccus denitrificans, with which is shares the character of a nicked 23S rRNA. Although the budding isolate IFAM 1031 resembles members of Blastobacter phenotypically, in the broad DNA G+C content and in the fatty acid pattern, a unique set of characters was found which allows description of the isolate as the typus of a new genus for which Gemmobacter gen. nov. is proposed, with G. aquatilis sp. nov. as the type species. G. aquatilis harbors at least two plasmids of different size and unknown function.
