Strains TEGAF015\n                    <jats:sup>T<\/jats:sup>\n                    and KACHI17\n                    <jats:sup>T<\/jats:sup>\n                    had cell dimensions of ~0.4\u20130.6\u00d71.3\u20132.9\u2009\u00b5m and 0.4\u20130.5\u00d72.5\u20134.8\u2009\u00b5m (width\u00d7length), respectively. Strain KACHI17\n                    <jats:sup>T<\/jats:sup>\n                    was positive for casein hydrolysis, whereas strain TEGAF015\n                    <jats:sup>T<\/jats:sup>\n                    was negative. Phylogenetic analyses based on the 16S rRNA gene (1,290\u2009bp) and 120 ubiquitous single-copy protein-encoding genes (5,035 aa) revealed that TEGAF015\n                    <jats:sup>T<\/jats:sup>\n                    and KACHI17\n                    <jats:sup>T<\/jats:sup>\n                    formed clusters closely related to\n                    <jats:italic>Sediminibacterium salmoneum<\/jats:italic>\n                    NJ-44\n                    <jats:sup>T<\/jats:sup>\n                    and\n                    <jats:italic>Sediminibacterium goheungense<\/jats:italic>\n                    HME7863\n                    <jats:sup>T<\/jats:sup>\n                    , respectively. However, the average nucleotide identity by orthology, average amino acid identity and digital DNA\u2013DNA hybridization values confirmed that the isolates represent distinct species from closest phylogenetic relatives. The major cellular fatty acids identified in both strains included iso-C\n                    <jats:sub>15:0<\/jats:sub>\n                    , iso-C\n                    <jats:sub>15:1<\/jats:sub>\n                    G, anteiso-C\n                    <jats:sub>15:0<\/jats:sub>\n                    and iso-C\n                    <jats:sub>17:0<\/jats:sub>\n                    3-OH. Additionally, TEGAF015\n                    <jats:sup>T<\/jats:sup>\n                    contained anteiso-C\n                    <jats:sub>15:1<\/jats:sub>\n                    A, iso-C\n                    <jats:sub>15:0<\/jats:sub>\n                    3-OH and iso-C\n                    <jats:sub>16:0<\/jats:sub>\n                    3-OH. Phosphatidylethanolamine was identified as the major polar lipid of strains TEGAF015\n                    <jats:sup>T<\/jats:sup>\n                    and KACHI17\n                    <jats:sup>T<\/jats:sup>\n                    , which also contained menaquinone-7 as the predominant respiratory quinone and had DNA G+C contents of 38.5 and 40.0 mol%, respectively. Genome sequencing of the two isolates revealed genome sizes of 3.06 and 3.14 Mbp, respectively. Furthermore, both isolates were capable of converting dissolved organic nitrogen into ammonium during growth. These results indicated that strains TEGAF015\n                    <jats:sup>T<\/jats:sup>\n                    and KACHI17\n                    <jats:sup>T<\/jats:sup>\n                    represent two distinct novel species within the genus\n                    <jats:italic>Sediminibacterium<\/jats:italic>\n                    .
