Strain 33A1-SZDP was isolated from a small creek located in Puch, Austria. Strain SP-Ram-0.45-NSY-1 was obtained from a small pond located in Schönramer Moor, Germany. 16S rRNA gene sequence similarities between the type strain of , currently the only member of the family , and strains 33A1-SZDP and SP-Ram-0.45-NSY-1 of 94.1 and 99.1 %, respectively, suggested affiliation of the two strains with this family. Phylogenetic reconstructions with 16S rRNA gene sequences and phylogenomic analyses with amino acid sequences obtained from 103 single-copy genes suggested that the strains represent a new genus and a new species in the case of strain 33A1-SZDP (=JCM 32978=DSM 107810), and a new species within the genus in the case of strain SP-Ram-0.45-NSY-1 (=JCM 32975=DSM 107809). Cells of strain 33A1-SZDP were motile, pleomorphic, purple-pigmented on agar plates, putatively due to violacein, and showed variable pigmentation in liquid media. They grew chemoorganotrophically and aerobically and tolerated salt concentrations up to 1.2 % NaCl (v/w). The genome size of strain 33A1-SZDP was 3.4 Mbp and the G+C content was 32.2 mol%. For this new genus and new species, we propose the name gen. nov., sp. nov. Cells of strain SP-Ram-0.45-NSY-1 were motile, pleomorphic, red-pigmented and grew chemoorganotrophically and aerobically. They tolerated salt concentrations up to 1.1 % NaCl (v/w). The genome size of strain SP-Ram-0.45-NSY-1 was 3.9 Mbp and the G+C content 29.3 mol%. For the new species within the genus we propose the name sp. nov.
菌株 33A1-SZDP 从位于奥地利普赫的一条小溪中分离得到。菌株 SP-Ram-0.45-NSY-1 从德国 Schönramer Moor 的一个小池塘中获得。目前该家族中唯一的成员与 33A1-SZDP 和 SP-Ram-0.45-NSY-1 菌株的 16S rRNA 基因序列相似性分别为 94.1%和 99.1%,表明这两个菌株与该家族有关。基于 16S rRNA 基因序列的系统发育重建和基于 103 个单拷贝基因的氨基酸序列的系统基因组分析表明,在 33A1-SZDP 菌株(=JCM 32978=DSM 107810)的情况下,这些菌株代表一个新属和一个新种,在 SP-Ram-0.45-NSY-1 菌株(=JCM 32975=DSM 107809)的情况下,这些菌株代表属内的一个新种。33A1-SZDP 菌株的细胞是运动的、多形的、琼脂平板上呈紫色色素,可能是由于紫色素,在液体培养基中显示出可变的色素。它们可以化能异养和好氧生长,并耐受高达 1.2%NaCl(v/w)的盐浓度。33A1-SZDP 菌株的基因组大小为 3.4 Mbp,G+C 含量为 32.2mol%。对于这个新属和新种,我们提出了 属名,新种名。SP-Ram-0.45-NSY-1 菌株的细胞是运动的、多形的、红色色素,化能异养和好氧生长。它们可以耐受高达 1.1%NaCl(v/w)的盐浓度。SP-Ram-0.45-NSY-1 菌株的基因组大小为 3.9 Mbp,G+C 含量为 29.3mol%。对于属内的新种,我们提出了 新种名。
