member of the family Dermacoccaceae isolated from a hot spring, and emended description of the family Dermacoccaceae

During the course of a study on the bacterial diversity in Western Ghats, India, an actinobacterial strain, designated PC IW02 T , was isolated and characterized by a polyphasic taxonomic approach. Strain PC IW02 T was a non-motile, Gram-positive, short rod that formed creamish white to yellow coloured colonies. 16S rRNA gene sequence analysis showed that the novel strain showed highest sequence similarity with type strains of members of the genus Dermacoccus: Dermacoccus barathri (96.6%), Dermacoccus profundi (96.5%), Dermacoccus abyssi (96.4%) and Dermacoccus nishinomiyaensis (95.9%). The phylogenetic tree suggested that strain PC IW02 T could represent a member of a new genus of the family Dermacoccaceae with the genus Demetria as closest clade. Pairwise sequence alignment with Demetria terragena HKI 0089 T and Kytococcus sedentarius DSM 20547 T showed similarities of 94.2 and 93.7%, respectively. Strain PC IW02 T had MK-8(H4) as the major menaquinone. The major fatty acids
