title: Description of a novel actinobacterium Kocuria assamensis sp. nov., isolated from a water sample collected from the river Brahmaputra, Assam, India.
abstract: A Gram-positive, pale yellow pigmented actinobacterium, strain S9-65(T) was isolated from a water sample collected from the river Brahmaputra, Assam, India and subjected to a polyphasic taxonomic study. The physiological and biochemical properties, major fatty acids (anteiso-C15:0 and anteiso-C17:0), estimated DNA G+C content (69.2 mol %) and 16S rRNA gene sequence analysis showed that strain S9-65(T) belonged to the genus Kocuria. Strain S9-65(T) exhibited highest 16S rRNA gene sequence similarity with Kocuria palustris (99.1%); however, the DNA-DNA relatedness value between strain S9-65(T) and K. palustris was 20.6%. On the basis of differential phenotypic characteristics and genotypic distinctiveness, strain S9-65(T) should be classified as representative of a novel species Kocuria, for which the name Kocuria assamensis is proposed. The type strain is S9-65(T) (=MTCC 10622(T) = DSM 23999(T)).
