NOV . Corticicoccus [Cor.ti.ci.coc′ cus. L. n. cortex bark; N.L. masc. n. coccus (from Gr. masc. n. kokkos grain, seed), coccus ; N.L. masc. n. Corticicoccus a coccoid from bark]. Cells are Gram-stain positive, aerobic, non-motile and coccoid. Colonies are milk-white, circular, opaque and convex with entire margins on TSA (pH 7). The optimal pH for growth is pH 7.0–8.0 and no growth is observed at pH 5. Positive for oxidase, catalase and b- glucosidase activities. Nitrate is not reduced to nitrite. The main menaquinone is MK-7. The peptidoglycan type is A3a based on L- Lys-Gly3-?Ala. The polar lipid profile contains diphosphatidylglycerol, phosphatidylglycerol, two unidentified phospholipids and three unidentified glycolipids. The major fatty acids are anteiso-C 15: 0 , iso-C 15: 0 , iso-C 17: 0 and anteiso-C 17: 0 . The DNA G+C content is 38.2 mol%. The type species is Corticicoccus populi .
