The strain grew within the temperature range 10–40 °C, at pH 5.5–11.0 and in the presence of 2 % NaCl. The DNA G+C content was 75.7 mol%, and its cell-wall peptidoglycan contained meso-diaminopimelic acid. Sugars of whole-cell hydrolysates were galactose, glucose, and trace amounts of ribose and mannose. The predominant menaquinone was MK-9(H4), and the major fatty acids were iso-C16 : 0 and C16 : 1 ω7c. The polar lipid profile comprised phosphatidylcholine, phosphatidylinositol, diphosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine and an unspecified glycolipid. 16S rRNA gene sequence analysis revealed that the strain fell into the genus Geodermatophilus , showing the highest similarity with Geodermatophilus poikilotrophus DSM 44209T (99.1 %). DNA–DNA hybridization results, phylogenetic distinctiveness and phenotypic properties supported the classification of this strain as a representative of a novel species of the genus Geodermatophilus , for which the name Geodermatophilus pulveris sp. nov. is proposed. The type strain is BMG 825T (=CECT 9003T=DSM 46839‏T).", }
