Abstract
A Gram-stain-positive, aerobic, non-motile and coccoid-shaped bacterium, designated XNB-1T, was isolated from farmland soil in Taian, Shandong province, China. Strain XNB-1T contained iso-C15 : 0 and iso-C16 : 0 as the predominant fatty acids. The diagnostic diamino acid of the peptidoglycan was ornithine, and the interpeptide bridge was l-Orn←Gly(1, 2)←d-Glu. The polar lipid profile of strain XNB-1T consisted of diphosphatidylglycerol, phosphatidylglycerol, an unidentified phosphoglycolipid and three unidentified phospholipids. The predominant menaquinone of strain XNB-1T was MK-8(H4) and the DNA G+C content was 70.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain XNB-1T belonged to the genus
Ornithinicoccus
, and shared the highest similarity with
Ornithinicoccus hortensis
HKI 0125T (96.0 %), followed by
Ornithinicoccus halotolerans
EGI 80423T (95.5 %). Genome-based analysis of average nucleotide identity of strain XNB-1T with
O. hortensis
HKI 0125T and
O. halotolerans
EGI 80423T yielded values of 73.1 and 73.3 %, respectively, while the digital DNA–DNA hybridization values were 19.5 and 19.9 %, respectively. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain XNB-1T is considered to represent a novel species of the genus
Ornithinicoccus
, for which the name Ornithinicoccus soli sp. nov. is proposed. The type strain is XNB-1T (=CCTCC AB 2019099T=KCTC 49259T).
