Abstract:
A novel Gram-negative coccus/coccobacillus, strain Ben 114 T , growing in tetrads, clusters or aggregates, was isolated from activated sludge by micromanipulation. 16S rRNA gene sequence analysis revealed that it belonged to the ‘ Alphaproteobacteria ’, with no close relatives among cultured bacterial isolates. On the basis of phylogenetic data, this organism is considered to belong to a new genus, Defluvicoccus , represented by the species Defluvicoccus vanus sp. nov., a name chosen because of the distinctive staining properties of this organism; only the cell wall stained strongly with a wide range of stains, giving the cell a hollow and empty appearance. No intracellular polyphosphate granules could be detected after staining, but poly- β -hydroxyalkanoate inclusions were detected using Nile blue A staining. Because of its taxonomic distance from its closest relatives among the ‘ Alphaproteobacteria ’, namely members of the genera Azospirillum , Phaeospirillum , Rhodospirillum , Rhodocista , Magnetospirillum and Rhodospira , D. vanus is considered to represent a new phylogenetic lineage within subgroup 1 of the ‘ Alphaproteobacteria ’, the D. vanus subgroup. The type strain is Ben 114 T (=NCIMB 13612 T =CIP 107350 T ).
