“…The genome sequence features of strain MAH-29 T are shown in Table S1. The genomic DNA G+C content of strain MAH-29 T , directly calculated from its genome sequence, was 43.8 mol% which is in the range of the previously described species of the genus Niastella [1][2][3][4][5][6]. The differences in genomes between strain MAH-29 T and the closest related type strains (N. vici DJ57 T , N. koreensis GR20-10 T and N. yeongjuensis GR20-13 T ) are shown in Table S2.…”

“…They contain menaquinone 7 (MK-7) as the predominant respiratory ubiquinone and iso-C 15:0 , iso-C 15:1 G and iso-C 17:0 3OH as the major fatty acid components. The DNA G+C content of members of this genus ranges from 41.4 to 45.8 mol% [1–6]. In this study, we report on the isolation and characterization of a novel bacterial species of the genus Niastella , represented by strain MAH-29 T , isolated from rhizospheric soil of a persimmon tree.…”

“…At the time of writing, this genus comprises only seven species: Niastella casei [3], Niastella vici [4], Niastella koreensis [1], Niastella yeongjuensis [1], Niastella populi [2], Niastella gongjuensis [5] and Niastella hibisci [6]. All of these species were isolated from different soil samples except for N. casei , which was isolated from activated sludge [1–6]. Cells of all species of the genus Niastella are Gram-stain-negative, aerobic and rod-shaped.…”

A Gram-stain-negative, aerobic, motile and rod-shaped novel bacterial strain, designated MAH-29T, was isolated from rhizospheric soil of a persimmon tree. The colonies were light pink coloured, smooth, spherical and 0.1–0.8 mm in diameter when grown on Reasoner's 2A (R2A) agar for 2 days. Strain MAH-29T was able to grow at 20–37 °C, at pH 5.0–8.5 and at 0–2.0 % NaCl. Cell growth occurred on nutrient agar and R2A agar. The strain was positive in both oxidase and catalase tests. According to the 16S rRNA gene sequence comparisons, the isolate was identified as a member of the genus Niastella and was closely related to Niastella vici DJ57T (97.7 % similarity), Niastella koreensis GR20-10T (97.1 %) and Niastella yeongjuensis GR20-13T (97.0 %). Strain MAH-29T has a draft genome size of 8 876 333 bp (31 contigs), annotated with 6920 protein-coding genes, 61 tRNA and four rRNA genes. The average nucleotide identity and digital DNA–DNA hybridization values between strain MAH-29T and three closely related type strains were in the range of 78.2–83.2 % and 22.1–27.0 %, respectively. The genomic DNA G+C content was 43.8 mol%. The predominant isoprenoid quinone was menaquinone 7. The major fatty acids were identified as iso-C15:0, iso-C15:1 G and iso-C17:0 3OH. On the basis of DNA–DNA hybridization results, genotypic analysis and chemotaxonomic and physiological data, strain MAH-29T represents a novel species within the genus Niastella , for which the name Niastella soli sp. nov. is proposed, with MAH-29T (=KACC 19969T=CGMCC 1.16606T) as the type strain.
