Abstract

A Gram-negative, non-motile, oval to rod-shaped, psychrotolerant, phototrophic, purple non-sulfur bacterium (designated strain JA139) was isolated from a snow sample from Changla Pass in the Indian Himalayas. Strain JA139 had vesicular-type intracytoplasmic membrane structures and contained bacteriochlorophyll and most probably spheroidene-like carotenoids. Biotin, niacin and thiamine were required for growth of strain JA139. Phylogenetic analysis on the basis of 16S rRNA gene sequences showed that the strain clustered with species of the genus but was distinctly separate from all recognized members of the family . Based on the genotypic and phenotypic differences observed between strain JA139 and recognized species, strain JA139 is considered to represent a novel species of the genus, for which the name sp. nov. is proposed. The type strain is JA139 (=DSM 18774 =CCUG 53722 =JCM 14338).
