Actinobacteria / Actinobacteria / Micrococcales / Dermacoccaceae / Demetria

Cells are irregularly coccoid to rod-shaped, 0.8–1.2 × 0.8–3.0 µm. They occur singly, in pairs, short chains, or in small irregular clusters. Gram-stain-positive. Not acid fast. Nonsporeforming. Nonmotile. Aerobic to microaerobic. Colonies are circular, smooth, convex, white to pale yellow, and 1–3 mm in diameter. Optimum temperature for growth is 28°C; no growth occurs at 37°C. Oxidase negative, catalase positive. The peptidoglycan type is A4α with L-lysine as the characteristic diamino acid. The acyl type is acetyl. Galactose is the only whole-cell sugar. The only respiratory quinone is MK-8(H₄ ). The polar lipids are composed of phosphaditylinositol, phophaditylglycerol, diphophaditylglycerol, phosphatidylethanolamine, and two unknown phospholipids. The cellular fatty acid profile is complex with large amounts of saturated and monounsaturated straight-chain acids and smaller amounts of iso- and anteiso-branched-chain acids. Mycolic acids are absent. Based on 16S rRNA gene sequence comparison, the genus Demetria is most closely related to members of the genera Dermacoccus and Kytococcus.

DNA G+C content (mol%): 66.
