title: Luteipulveratus mongoliensis gen. nov., sp. nov., an actinobacterial taxon in the family Dermacoccaceae.
abstract: A novel actinobacterial strain, MN07-A0370(T), was isolated from Mongolian soil and its taxonomic status was determined using a polyphasic approach. Comparative 16S rRNA gene sequence studies revealed that strain MN07-A0370(T) represented a novel lineage within the actinobacteria. Strain MN07-A0370(T) formed a distinct clade in the family Dermacoccaceae and was most closely related to the members of the genera Dermacoccus (16S rRNA gene sequence similarity, 96.2 %-96.4 %), Demetria (94.1 %) and Kytococcus (93.7 %). The cell-wall peptidoglycan of the novel strain contained l-lysine, alanine, aspartic acid, glutamic acid and serine and represented peptidoglycan type A4alpha. The menaquinones were MK-8(H(4)) and MK-8(H(6)). The polar lipids were phosphatidylglycerol, diphosphatidylglycerol and phosphatidylinositol and the whole-cell sugars were galactose, mannose, rhamnose, ribose and glucose. Mycolic acids were absent. The fatty acid profile was characterized by the presence of large amounts of saturated iso- and anteiso-branched-chain fatty acids as well as smaller amounts of saturated straight-chain and unsaturated acids. The major fatty acids were iso-C(16 : 0), anteiso-C(17 : 0), iso-C(16 : 1) H, C(17 : 1)omega9c and C(17 : 0) 10-methyl. The G+C content of the DNA was 68.2 mol%. On the basis of chemotaxonomic, physiological and biochemical differences from other genera of the family Dermacoccaceae, strain MN07-A0370(T) should be classified as representing a novel species in a new genus, for which we propose the name Luteipulveratus mongoliensis gen. nov., sp. nov. The type strain is MN07-A0370(T) (=NBRC 105296(T)=VTCC D9-09(T)).
