“…The obtained ANI and dDDH between XZ-24 T and the species of the family Caulobacteraceae were 64.5–75.5 % and 18.6–30.3%, respectively (), which was far below the threshold values (ANI 95–96 % and DDH 70 %) recommended for prokaryotic species delineation, supporting the hypothesis that XZ-24 T represent a novel species within the family Caulobacteraceae . AAI was considered a reliable tool for distinguishing higher taxonomic ranks than species [36]. The AAI values between XZ-24 T and the species of the family Caulobacteraceae were 47.0–64.5 % (), which were below the genus boundary (70 %) [37], supporting the proposal that strain XZ-24 T should represent a novel genus of the family Caulobacteraceae .…”

A Gram-stain-negative bacterium, designated XZ-24T, was isolated from sediment of a river in Mianyang city, Sichuan province, PR China. Cells (1.0–2.0 µm long and 0.4–0.5 µm in width) were strictly aerobic, non-spore-forming, rod shaped, prosthecate and motile by means of a polar flagellum. Growth occurred at 10–37 °C (optimum, 30 °C), at pH 5.0–9.0 (optimum pH 7.0) and with 0–3.0 % (w/v) NaCl (optimum 1.0 % NaCl). The results of phylogenetic analysis based on genomes and 16S rRNA gene sequences indicated that XZ-24T formed a distinct phyletic branch within the family Caulobacteraceae and was most closely related to members of the genera Brevundimonas, Caulobacter and Phenylobacterium with 95.3–96.5 % 16S rRNA gene sequence similarities. The average amino acid identities (AAI) between XZ-24T and species of the family Caulobacteraceae were 47.0–64.5 %, which were below the genus boundary (70 %). The predominant cellular fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), C16 : 0, C18 : 1ω7c 11-methyl and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), the isoprenoid quinone was Q-10, and the major polar lipids were 1,2-di-O-acyl-3-O-α-d-glucopyranuronosyl glycerol; 1,2-di-O-acyl-3-O-[d-glucopyranosyl-(1→4)-α-d glucopyranuronosyl] glycerol and phosphatidylglycerol. The genome size of XZ-24T was 2.64 Mb with a DNA G+C content of 68.9 %. On the basis of the evidence presented in this study, strain XZ-24T represents a novel species of a novel genus in the family Caulobacteraceae, for which the name Peiella sedimenti gen. nov., sp. nov. (Type strain XZ-24T=CCTCC AB 20 23 094T=KCTC 8038T) is proposed.

“…The obtained ANIs between R-40 T and the type strains of species in the related genera were 69.3–74.1 %, which were below the 80 % standard threshold recommended for identification of a novel genus [27]; the obtained dDDH between R-40 T and the type strains of species of the related genera were 18.2–21.5 %. AAI is considered a reliable tool for distinguishing higher taxonomic ranks than species [28].

A Gram-stain-negative bacterium, designated as R-40T, was isolated from sediment of the Mulong river in Mianyang city, Sichuan province, PR China. The cells of strain R-40T were aerobic non-motile and formed translucent white colonies on R2A agar. Growth occurred at 15–37 °C (optimum 30 °C), pH 5.0–9.0 (optimum 7.0) and salinities of 0–3.0 % (w/v, optimum 0 %). R-40T showed 95.2–96.6 % 16S rRNA gene sequence similarities with the type strains of species of the genera Oxalicibacterium, Herminiimonas, Lacisediminimonas, Paucimonas, Herbaspirillum and Noviherbaspirillum in the family Oxalobacteraceae. The results of phylogenetic analysis based on genome sequences indicated that the strain was clustered with type strains of species of the genera Oxalicibacterium and Herminiimonas in the family Oxalobacteraceae but formed a distinct lineage. The average nucleotide identity (ANI), digital DNA–DNA hybridization (dDDH) and average amino acid identity (AAI) values between R-40T and type strains of species of the genera Oxalicibacterium, Herminiimonas, Lacisediminimonas, Paucimonas, Herbaspirillum and Noviherbaspirillum ranged from 69.3 to 74.1 %, from 18.2 to 21.4 % and from 60.1 to 67.4 %, respectively. The major cellular fatty acids were C16 : 0, C17 : 0 cyclo and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The major quinone was ubiquinone-8 (Q-8). The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phospholipid and small amounts of glycophospholipids. The genome size of R-40T was 5.1 Mbp with 54.0 % DNA G+C content. On the basis of the evidence presented in this study, strain R-40T represents a novel species of a novel genus in the family Oxalobacteraceae, for which the name Keguizhuia sedimenti gen. nov., sp. nov. (type strain R-40T=MCCC 1K08818T=KCTC 8137T) is proposed.

“…The obtained ANI and dDDH values between strain LG-4 T and the related type strains of the family Paracoccaceae were 74.19–77.56 % and 16.70–25.80 %, respectively (), which are far below the threshold values (ANI 95 % and dDDH 70 %) recommended for prokaryotic species delineation [33], suggesting that strain LG-4 T should represent a novel species within the family Paracoccaceae . AAI is considered a reliable tool for distinguishing taxonomic ranks higher than species [34]. The AAI values between strain LG-4 T and the genera of the family Paracoccaceae were 60.94–69.73 % (), which are below the genus boundary (70 %) [9], further supporting that strain LG-4 T should represent a novel genus of the family Paracoccaceae .…”

A Gram-stain-negative bacterium, designated LG-4T, was isolated from sediment of Qiantang River in Zhejiang Province, PR China. Cells were strictly aerobic, non-spore-forming, non-motile and short-rod-shaped (1.0–1.2 µm long and 0.7–0.8 µm wide). Growth occurred at 15–42 °C (optimum, 30 °C), at pH 5.0–9.0 (pH 7.0) and at 0–2.0 % (w/v) NaCl (optimum, 0.5 % NaCl). Strain LG-4T showed 95.75–96.90 % 16S rRNA gene sequence similarity to various type strains of the genera Tabrizicola, Pseudotabrizicola, Phaeovulum, Rhodobacter and Wagnerdoeblera of the family Paracoccaceae, and the most closely related strain was Tabrizicola soli ZQBWT (96.90 % similarity). The phylogenomic tree showed that strain LG-4T clustered in the family Paracoccaceae and was positioned outside of the clade composed of the genera Wagnerdoeblera and Falsigemmobacter. The average nucleotide identity and digital DNA–DNA hybridization values between strain LG-4T and the related type strains were in the range of 74.19–77.56 % and 16.70–25.80 %, respectively. The average amino acid identity (AAI) values between strain LG-4T and related type strains of the family Paracoccaceae were 60.94–69.73 %, which are below the genus boundary (70 %). The evolutionary distance (ED) values between LG-4T and the related genera of the family Paracoccaceae were 0.21–0.34, which are within the recommended standard (≥0.21–0.23) for defining a novel genus in the family Paracoccaceae. The predominant cellular fatty acids were C18 : 1 ω7c, C19 : 0 cyclo ω8c, C18 : 0 and C16 : 0, the isoprenoid quinone was Q-10, and the major polar lipids were phospholipid, phosphatidylglycerol, phosphatidylcholine, aminolipid and two unknown polar lipids. The genome size was 4.7 Mb with 68.6 mol% G+C content. On the basis of distinct phylogenetic relationships, low AAI values and high ED values, and differential phenotypic, physiological and biochemical characteristics, strain LG-4T represents a novel species of a new genus in the family Paracoccaceae, for which the name Ruixingdingia sedimenti gen. nov., sp. nov. is proposed. The type strain is LG-4T (=MCCC 1K08849T=KCTC 8136T)
