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.

蓝花Stappia alba sp。十一月，与地中海牡蛎隔离。

从西班牙地中海沿岸的牡蛎中分离出的三种细菌菌株已在表型和遗传上得到了表征。基于几乎完整的16S rDNA序列的系统发育分析结果将所有三个菌株聚集在一起，具有99.9％的平均序列相似性，并将其置于Stappia，Rosibium和Pannonibacter属的附近，而Stappia aaggregata是它们的最近邻居，序列相似性在98.8之间。 ％和98.9％。使用菌株5OM6T和集合链球菌CECT 4269T的DNA作为参考DNA的DNA-DNA杂交实验证实了牡蛎分离物在物种水平上的独立状态。从表型上看，它们可以通过离子需求，生长温度和碳化合物的使用与最接近的亲戚区分开。我们建议这些牡蛎菌株构成Stappia的新物种，其名称为Stappia alba sp。十一月 选择了菌株5OM6T（= CECT 5095T = CIP 108402T）作为其类型菌株。
