Planctomycetes is a ubiquitous phylum of mostly aquatic bacteria that have a complex lifestyle and an unusual cell biology. Here, we describe three strains of the same novel genus and species isolated from three different environments; from a red biofilm at a hydrothermal vent in the Mediterranean Sea, from sediment in a salt-water fish tank, and from the surface of algae at the coast of the Balearic island Mallorca. The three strains Mal65 (DSM 100706 = LMG 29792, Pan14r (DSM 29351 = LMG 29012), and V7 (DSM 29812 = CECT 9853 = VKM B-3427) show typical characteristics of the Planctomycetaceae family, such as cell division by budding, crateriform structures and growth in aggregates or rosettes. The strains are mesophilic, neutrophilic to alkaliphilic as well as chemoheterotrophic and exhibit doubling times between 12 and 35 h. Based on our phylogenetic analysis, the three strains represent a single novel species of a new genus, for which we propose the name Crateriforma conspicua gen. nov. sp. nov.
浮霉菌门是一个普遍存在的细菌门类，大多生活在水生环境中，具有复杂的生活方式和独特的细胞生物学特性。在此，我们描述了从三种不同环境中分离出的同一新属新种的三株菌株；分别来自地中海一处热液喷口的红色生物膜、一个海水鱼缸的沉积物以及巴利阿里群岛马略卡岛海岸藻类的表面。这三株菌株分别为Mal65（DSM 100706 = LMG 29792）、Pan14r（DSM 29351 = LMG 29012）和V7（DSM 29812 = CECT 9853 = VKM B - 3427），它们展现出浮霉菌科的典型特征，如通过出芽进行细胞分裂、火山口状结构以及以聚集体或玫瑰花结形式生长。这些菌株为嗜温菌，嗜中性至嗜碱性，属于化能异养型，倍增时间在12至35小时之间。基于我们的系统发育分析，这三株菌株代表了一个新属中的单一新物种，我们为此提议将其命名为显著火山口菌属新属新种（Crateriforma conspicua gen. nov. sp. nov.）。
