The genus Roseomonas is a significant group of bacteria which is invariably of great clinical and ecological importance. Previous studies have shown that the genus Roseomonas is polyphyletic in nature. Our present study focused on generating a lucid understanding of the phylogenetic framework for the re-evaluation and reclassification of the genus Roseomonas. Phylogenetic studies based on the 16S rRNA gene and 92 concatenated genes suggested that the genus is heterogeneous, forming seven major groups. Existing Roseomonas species were subjected to an array of genomic, phenotypic, and chemotaxonomic analyses in order to resolve the heterogeneity. Genomic similarity indices (dDDH and ANI) indicated that the members were well-defined at the species level. The Percentage of Conserved Proteins (POCP) and the average Amino Acid Identity (AAI) values between the groups of the genus Roseomonas and other interspersing members of the family Acetobacteraceae were below 65 and 70%, respectively. The pan-genome evaluation depicted that the pan-genome was an open type and the members shared 958 core genes. This claim of reclassification was equally supported by the phenotypic and chemotaxonomic differences between the groups. Thus, in this study, we propose to re-evaluate and reclassify the genus Roseomonas and propose six novel genera as Pararoseomonas gen. nov., Falsiroseomonas gen. nov., Paeniroseomonas gen. nov., Plastoroseomonas gen. nov., Neoroseomonas gen. nov., and Pseudoroseomonas gen. nov.

An aerobic, non-motile, Gram-stain-negative, pink, convex, coccobacilli-shaped, mesophilic bacterium, designated strain BU-1T, was isolated from an urban soil sample from Zibo city, Shandong province, PR China. The strain grew at 20–37 °C (optimum, 30 °C), pH 5–10 (optimum, pH 7) and growth occurred with 0–2 % (w/v) NaCl (optimally with 0.5 %). The results of phylogenetic analysis based on 16S rRNA gene sequences indicated that BU-1T was closely related to members of the genus Roseomonas and had highest 16S rRNA gene sequence similarities with Roseomonas frigidaquae JCM 15073T (97.8 %), Roseomonas tokyonensis JCM 14634T (96.9 %), Roseomonas stagni JCM 15034T (96.5 %), and Roseomonas riguiloci JCM 17520T (95.9 %). BU-1T also formed a subcluster with R. frigidaquae JCM 15073T and R. stagni JCM 15034T in phylogenetic trees based on genomic sequences. The genome size of BU-1T was 5.79 Mb and the DNA G+C content was 71.7 %. ANI, dDDH and AAI values between BU-1T and R. frigidaquae JCM 15073T were 84.0, 27.2 and 86.7 %, respectively. Furthermore, the genome of BU-1T contained 5446 predicted protein coding genes and 4945 (90.8%) of them had classifiable functions. BU-1T contained Q-10 as the main ubiquinone. The predominant fatty acids (>10 %) were summed feature 3, summed feature 8 and C16:0. The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and five unidentified aminolipids. Combined data from phenotypic, phylogenetic and chemotaxonomic studies indicated that strain BU-1T is a representative of a novel species of the genus Roseomonas . Since strain BU-1T can reduce highly toxic selenite [Se(IV)] to low toxicity elemental selenium [Se(0)], the name Roseomonas selenitidurans sp. nov. is proposed. The type strain is BU-1T (=KACC 21750T =GDMCC 1.1776T).

“…The members of the genus Roseomonas are generally characterized as Gram-stain-negative, strictly aerobic and pink-pigmented. Members of the genus Roseomonas have been isolated from various environmental habitats, including water [2–4], cooling tower and water-cooling systems [5, 6], air conditioners [7, 8], soil [9–11], an oil-contaminated site [12], sediment [13–15] and clinical specimens [1, 16]. Because it has been reported that some microbes living in algal spheres influence algal growth through some interactions, alga-associated bacteria have attracted a great deal of attention in order to understand algal growth [17].…”

A Gram-stain-negative, strictly aerobic bacterium, designated strain PeD5T, was isolated from a green alga Pediastrum duplex from the Nakdong river of the Republic of Korea. Cells were non-motile cocci, catalase-negative and oxidase-positive. Growth of PeD5T was observed at 25–40 °C (optimum, 35 °C) and pH 5.0–10.0 (optimum, pH 7–8), and in the presence of 0–0.25% (w/v) NaCl (optimum, 0%). PeD5T contained C16:0, C18:1ω7c 11-methyl, summed feature 3 (comprising C16:1ω7c and/or C16:1ω6c) and summed feature 8 (comprising C18:1ω7c and/or C18:1ω6c) as major cellular fatty acids (>5%) and ubiquinone-10 as the sole isoprenoid quinone. Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unidentified phospholipid and an unidentified aminolipid were detected as major polar lipids. The genomic DNA G+C content of PeD5T was 71.0 mol%. PeD5T was most closely related to Roseomonas stagni HS-69T with a 97.6% 16S rRNA sequence similarity and shared less than 96.3% 16S rRNA sequence similarities with type strains of other species. Phylogenetic analysis based on 16S rRNA gene sequences indicated that PeD5T formed a phyletic lineage with Roseomonas stagni HS-69T within the genus Roseomonas . On the basis of results of phenotypic, chemotaxonomic and molecular analysis, strain PeD5T clearly represents a novel species of the genus Roseomonas , for which the name Roseomonas algicola sp. nov. is proposed. The type strain is PeD5T (=KACC 19925T=JCM 33309T).
