放线菌占淡水湖泊和溪流中浮游细菌的很大一部分。许多独立于培养的研究已从这些栖息地检索到放线菌 16S rRNA 基因序列。在淡水生境中检测到的类群通常在陆地和海洋系统中不存在。到目前为止，没有一个本地淡水谱系是由具有有效公布名称的分类单元代表的。这里描述的候选状态的七种生物体是从位于热带、亚热带和温带气候区的淡水湖泊和池塘中分离出来的。系统发育分析表明，它们属于淡水浮游细菌固有的放线菌谱系之一。迄今为止，这七种新类群只能作为也含有非放线菌菌株的混合培养物进行培养。由于缺乏纯培养物，我建议为这些物种建立候选物种‘Candidatus Planktoluna difficilis’、‘Candidatus Aquiluna rubra’、‘Candidatus Flaviluna lacus’、‘Candidatus Rhodoluna limnophila’、‘Candidatus Rhodoluna planktonica’、‘Candidatus Rhodoluna lacicola’和‘Candidatus Limnoluna rubra’。类群。
Actinobacteria comprise a substantial fraction of the bacterioplankton in freshwater lakes and streams. Numerous cultivation-independent investigations have retrieved actinobacterial 16S rRNA gene sequences from such habitats. The taxa detected in freshwater habitats are usually absent from terrestrial and marine systems. So far, none of the indigenous freshwater lineages is represented by a taxon with a validly published name. The seven organisms for which Candidatus status is described here were isolated from freshwater lakes and ponds located in tropical, subtropical and temperate climatic zones. Phylogenetic analyses demonstrated that they are affiliated with one of the actinobacterial lineages indigenous to freshwater bacterioplankton. The seven novel taxa could only be cultivated to date as mixed cultures that also contain non-actinobacterial strains. Due to the lack of pure cultures, I propose to establish the candidate species ‘Candidatus Planktoluna difficilis’, ‘Candidatus Aquiluna rubra’, ‘Candidatus Flaviluna lacus’, ‘Candidatus Rhodoluna limnophila’, ‘Candidatus Rhodoluna planktonica’, ‘Candidatus Rhodoluna lacicola’ and ‘Candidatus Limnoluna rubra’ for these taxa.
