Planctomycetes is a fascinating phylum of mostly aquatic bacteria, not only due to the environmental importance in global carbon and nitrogen cycles, but also because of a unique cell biology. Their lifestyle and metabolic capabilities are not well explored, which motivated us to study the role of Planctomycetes in biofilms on marine biotic surfaces. Here, we describe the novel strain Pan54 which was isolated from algae in a hydrothermal area close to the volcanic island Panarea in the Tyrrhenian Sea, north of Sicily in Italy. The strain grew best at pH 9.0 and 26 °C and showed typical characteristics of planctomycetal bacteria, e.g. division by polar budding, formation of aggregates and presence of stalks and crateriform structures. Phylogenetically, the strain belongs to the genus Rubinisphaera. Our analysis suggests that Pan54 represents a novel species of this genus, for which we propose the name Rubinisphaera italica sp. nov. We suggest Pan54 (= DSM 29369 = LMG 29789) as the type strain of the novel species.
盘星藻门是一类主要生活在水中的细菌，它们不仅在全球碳氮循环中具有重要的环境意义，还具有独特的细胞生物学特性。它们的生活方式和代谢能力尚未得到充分探索，这促使我们研究盘星藻门在海洋生物表面生物膜中的作用。在这里，我们描述了一株从意大利西西里岛北部的第勒尼安海靠近火山岛帕纳雷阿的藻类中分离到的新型菌株 Pan54。该菌株在 pH 值 9.0 和 26°C 下生长最好，表现出典型的盘星藻细菌特征，例如极性出芽分裂、聚集形成以及存在柄和坑状结构。系统发育分析表明，该菌株属于 Rubinisphaera 属。我们的分析表明，Pan54 代表了该属的一个新种，我们建议将其命名为 Rubinisphaera italica sp. nov.。我们建议将 Pan54（=DSM 29369=LMG 29789）作为该新种的模式菌株。
