Cells of the isolate were Gram-staining-positive, aerobic, non-motile cocci. Good growth was observed at 28 °C (range 20–40 °C), pH 7.0 (range pH 6.0–8.0) and 0–1 % NaCl concentration (range 0–5 %, w/v). Galactose, arabinose and ribose were detected as the sugar compositions in the whole cell hydrolysates. The peptidoglycan type was A3gamma (ll-Dpm-Gly). MK-9(H4) was detected as the predominant menaquinone, and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, several unidentified glycolipids, and one unidentified amino-glycolipid were detected as the major polar lipids. The predominant fatty acid was anteiso-C15 : 0. The genomic DNA G+C content was 73.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CPCC 204711T affiliated to the family Propionibacteriaceae , in which the strain formed a distinct phylogenetic lineage next to the genus Mariniluteicoccus , with the highest 16S rRNA gene sequence similarity of 96.0 % to Mariniluteicoccus endophyticus YIM 2617T. Both phylogenetic analysis and phenotypic characteristics supported that strain CPCC 204711T represents a novel species of a new genus in the family Propionibacteriaceae , for which the name Desertihabitans aurantiacus gen. nov., sp. nov. is proposed, with CPCC 204711T (=KCTC 39977T=DSM 105431T) as the type strain., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.003519
