A coral-red-pigmented actinobacterium, strain K30-10(T), was isolated from a soil sample from a cold desert of the Indian Himalayas. Chemical and phenotypic properties of strain K30-10(T) were consistent with its classification in the genus Dietzia. It showed 97(.)9% 16S rRNA gene sequence similarity to Dietzia maris MTCC 7011(T); similarities to the type strains of three other species of the genus, Dietzia natronolimnaea,. Dietzia psychralcaliphila and Dietzia cinnamea, were 94(.)4-96(.)0%. The DNA-DNA relatedness between K30-10(T) and the closely related strain D. maris MTCC 7011(T) was 59(.)2%. The DNA G+C content of strain K30-10(T) was 67(.)0 mol%. Based on physiological and biochemical tests and genotypic differences between strain K30-10(T) and its closest phylogenetic relatives, it is proposed that this strain represents a novel species, Dietzia kunjamensis sp. nov.; the type strain is K30-10(T) (=MTCC 7007(T) = DSM 44907(T)=jCM 13325(T)).
