Abstract:
:16S rRNA gene sequenced-based phylogeny indicates that Rhizobacter dauci ATCC 43778(T) branches within the radiation of Methylibium type strains. A comparative chemotaxonomic study including fatty acid methyl esters, polar lipids and polyamines reveals significant differences that, in combination with the topology of phylogenetic trees, support a dissection of the genus Methylibium. The proposals of this study include the transfer of Methylibium fulvum to the genus Rhizobacter as Rhizobacter fulvus comb. nov. (type strain Gsoil 322(T) =KCTC 12591(T) =DSM 19916(T)) and the reclassification of Methylibium aquaticum as Piscinibacter aquaticus gen. nov., comb. nov. (the type strain of Piscinibacter aquaticus is IMCC1728(T) =KCCM 42364(T) =NBRC 102349(T) =DSM 19915(T)) and of Methylibium subsaxonicum as Rivibacter subsaxonicus gen. nov., comb. nov. (the type strain of Rivibacter subsaxonicus is BF49(T) =DSM 19570(T) =CIP 109700(T)). As a consequence of these reclassifications, emended descriptions of the genera Methylibium and Rhizobacter are provided.
