title: Ornithinicoccus halotolerans sp. nov., and emended description of the genus Ornithinicoccus.
abstract: A halotolerant actinobacterial strain, designated EGI 80423T, was isolated from a desert soil of Xinjiang, north-west China, and subjected to a polyphasic taxonomic characterization. Strain EGI 80423T grew at pH 7.0-10.0 and with 0-14.0% (w/v) NaCl, optimally at pH 8.0-9.0 and with 2.0-4.0% (w/v) NaCl. Cells of strain EGI 80423T were Gram-stain-positive, non-motile cocci with diameters of 0.6-0.8 μm. The diagnostic diamino acid of the peptidoglycan was ornithine, and the interpeptide bridge was Orn ← Glu. The major fatty acids identified were iso-C17:1ω9c, iso-C15:0 and iso-C17:0. The predominant menaquinone was MK-8(H4), while the polar lipids were diphosphatidylglycerol, phosphatidylglycerol, two unknown phospholipids, two unknown glycolipids, six unknown phosphoglycolipids and five unknown polar lipids. The G+C content of the genomic DNA was 72.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain EGI 80423T clustered with the single member of the genus Ornithinicoccus. Sequence similarity between strain EGI 80423T and Ornithinicoccus hortensis NBRC 16434T. Because the type strain has been provided by NBRC, Japan was 97.7%. The DNA-DNA relatedness value between strain EGI 80423T and O. hortensis NBRC 16434T was 36.84%. Based on morphological, chemotaxonomic and phylogenetic characteristics, and DNA-DNA hybridization data, strain EGI 80423T represents a novel species of the genus Ornithinicoccus, for which the name Ornithinicoccus halotolerans sp. nov. is proposed. The type strain is EGI 80423T (=CGMCC 1.14989T=KCTC 39700T). The description of the genus Ornithinicoccus has also been emended.
