title: Stappia alba sp. nov., isolated from Mediterranean oysters.
abstract: Three bacterial strains isolated from oysters recovered at the Spanish Mediterranean coast have been phenotypically and genetically characterized. The results of the phylogenetic analysis based on almost complete 16S rDNA sequences clustered all three strains together with 99.9% average sequence similarity and situated them in the neighbourhood of the genera Stappia, Roseibium and Pannonibacter, Stappia aggregata being their closest neighbour with sequence similarities between 98.8% and 98.9%. DNA-DNA hybridization experiments using DNA of strains 5OM6T and S. aggregata CECT 4269T as reference DNAs confirmed the independent status at species level of the oyster isolates. Phenotypically, they can be distinguished from the closest relatives by the ionic requirements, growth temperatures and use of carbon compounds. We propose these oyster strains constitute a new species of Stappia, for which the name Stappia alba sp. nov. has been chosen, and strain 5OM6T (= CECT 5095T = CIP 108402T) as its type strain.
