Abstract

A Gram-positive, yellow pigmented actinobacterium, strain S2-48(T) was isolated from water sample collected from the river Brahmaputra, Assam, India and subjected to a polyphasic taxonomic study. Most of the physiological and biochemical properties, major fatty acids (C(15:0) Anteiso, iso C(16:0) and C(17:0) Anteiso), estimated DNA G+C content (70.2 mol%) and 16S rRNA gene sequence analysis showed that strain S2-48(T) belonged to the genus Microbacterium. Strain S2-48(T) exhibited highest 16S rRNA gene sequence similarity with Microbacterium testaceum (97.0%); however, the DNA-DNA relatedness value between strain S2-48(T) and M. testaceum was 9.1%. On the basis of differential phenotypic characteristics and genotypic distinctiveness, strain S2-48(T) should be classified within the genus Microbacterium as a novel species, for which the name Microbacterium assamensis is proposed. The type strain is S2-48(T) (=MTCC 10486(T) = DSM 23998(T)).
