A novel planctomycetal strain, designated Q31a, was isolated from a jellyfish at the shore of the island Helgoland in the North Sea. The strain forms lucid white colonies on solid medium and displays typical characteristics of planctomycetal strains, such as division by budding, formation of rosettes, presence of crateriform structures, extracellular matrix or fibre and a holdfast structure. Q31a is mesophilic (temperature optimum 27 °C), neutrophilic (pH optimum 7.5), aerobic and heterotrophic. A maximal growth rate of 0.017 h (generation time of 41 h) was observed. Q31a has a genome size of 8.44 Mb and a G + C content of 55.3%. Phylogenetically, the strain represents a novel genus and species in the recently introduced family Pirellulaceae, order Pirellulales, class Planctomycetia. We propose the name Aureliella helgolandensis gen. nov., sp. nov. for the novel species, represented by Q31a (= DSM 103537 = LMG 29700) as the type strain.
一株新的拟杆菌菌株 Q31a 是从北海赫尔戈兰岛海岸的水母中分离出来的。该菌株在固体培养基上形成清晰的白色菌落，并表现出拟杆菌属菌株的典型特征，如出芽分裂、形成玫瑰花结、存在坑状结构、细胞外基质或纤维和固着结构。Q31a 是中温型（最适温度 27°C）、嗜中性（最适 pH 值为 7.5）、需氧和异养的。观察到最大生长速率为 0.017 h（世代时间为 41 h）。Q31a 的基因组大小为 8.44 Mb，G+C 含量为 55.3%。系统发育上，该菌株代表了新近引入的 Pirellulaceae 科、Pirellulales 目、Planctomycetia 纲中的一个新属和新种。我们提议将新型物种命名为 Aureliella helgolandensis gen. nov.，sp. nov.，代表菌株为 Q31a（=DSM 103537=LMG 29700）作为模式菌株。
