Description of two novel species of the family Ornithinimicrobiaceae: Serinicoccus shuyuelongi sp. nov., and Ornithinimicrobium jinqii sp. nov., isolated from the faeces of the wild birds in the Qinghai–Tibet Plateau of China
Four strains (LYQ92<sup>T</sup>, LYQ131, LYQ121<sup>T</sup> and LYQ103) were isolated from the faeces of <i>Anser anser</i> and <i>Anser indicus</i> in the Qinghai, PR China. Phylogenetic analyses based on 16S rRNA gene and genome sequences demonstrated that strains LYQ92<sup>T</sup> and LYQ131 were adjacent to <i>Serinicoccus profundi</i> MCCC 1A05965<sup>T</sup> and <i>Serinicoccus sediminis</i> KCTC 49173<sup>T</sup>, while strains LYQ121<sup>T</sup> and LYQ103 were most closely related to <i>Ornithinimicrobium kibberense</i> DSM 17687<sup>T</sup>, <i>Ornithinimicrobium avium</i> KCTC 49180<sup>T</sup>, <i>Ornithinimicrobium tianjinense</i> CGMCC 1.12160<sup>T</sup> and <i>Ornithinimicrobium cerasi</i> CPCC 203383<sup>T</sup>. Four novel strains were Gram-stain positive, oxidase-negative, catalase-positive, aerobic, non-motile and coccoid- and rod-shaped. Strains LYQ92<sup>T</sup> and LYQ131 grew at 10-37 °C, pH 6.0-10.0 and 0-13.0% (wt/vol) NaCl, while strains LYQ121<sup>T</sup> and LYQ103 grew at 10-35 °C, pH 7.0-9.0 and 0-7.0% (wt/vol) NaCl. Both strains LYQ92<sup>T</sup> and LYQ121<sup>T</sup> had MK-8(H4) as the primary respiratory quinone and contained diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol. Major fatty acids of strains LYQ92<sup>T</sup> and LYQ131 were <i>iso</i>-C<sub>16:0</sub>, <i>iso</i>-C<sub>15:0</sub>, <i>anteiso</i>-C<sub>17:0</sub>, <i>anteiso</i>-C<sub>15:0</sub> and summed feature 9 (10-methyl C<sub>16:0</sub> and/or <i>iso</i>-C<sub>17:1</sub> ω9c), while those of strains LYQ121<sup>T</sup> and LYQ103 were <i>iso</i>-C<sub>16:0</sub>, <i>iso</i>-C<sub>15:0</sub> and summed feature 9. Strain LYQ92<sup>T</sup> contained ribose, glucose and galactose as major sugars and alanine, glutamic acid, serine, glycine, aspartic acid and ornithine as major amino acids. Strain LYQ121<sup>T</sup> had a similar composition but lacked galactose and serine. Based on polyphasic characterization, these strains represent two novel species within the family <i>Ornithinimicrobiaceae</i>, proposed as <i>Serinicoccus shuyuelongi</i> sp. nov. (type strain LYQ92<sup>T</sup>=GDMCC 1.5391<sup>T</sup>=KCTC 59547<sup>T</sup>) and <i>Ornithinimicrobium jinqii</i> sp. nov. (type strain LYQ121<sup>T</sup>=GDMCC 1.5402<sup>T</sup>=KCTC 59549<sup>T</sup>), respectively.
