The strain was a Gram-stain-positive, non-motile, non-spore-forming, catalase-positive, irregular rod-shaped bacterium. The strain grew at 4–45 °C and pH 5.0–10.2, and tolerated 5 % (w/v) NaCl. Based on its 16S rRNA gene sequence, the organism was related phylogenetically to members of the genera Fodinibacter (96.7 % similarity), Lapillicoccus (96.5 %), Knoellia (95.0–95.8 %), Oryzihumus (95.6 %) and Humibacillus (95.6 %). The cell-wall contained l-ornithine as the major diagnostic diamino acid in the peptidoglycan. MK-8(H4) was the predominant menaquinone. Major cellular fatty acids were iso-C18 : 1 ω9c, iso-C16 : 0, iso-C15 : 0 and C17 : 0. The G+C content of the DNA was 69.6 mol%. Phenotypic and phylogenetic data revealed that this strain represents a novel species in a new genus of the family Intrasporangiaceae, for which the name Ornithinibacter aureus gen. nov., sp. nov. is proposed; the type strain of Ornithinibacter aureus is HB09001T (=CGMCC 1.10341T =DSM 23364T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.022806-0
