ABSTRACT
An oval to rod-shaped, phototrophic, purple non-sulfur bacterium, strain JA192(T), was isolated from an enrichment culture of a pasteurized rhizosphere soil sample from a field cultivated with jowar (sorghum) collected from Godumakunta village near Hyderabad, India. Strain JA192(T) is Gram-negative, motile and produces endospores. Phylogenetic analysis on the basis of 16S rRNA gene sequences showed that the strain JA192(T) is closely related to Rhodobacter sphaeroides 2.4.1(T) (99.9 % sequence similarity), Rba. megalophilus JA194(T) (99.8 %) and Rba. azotoformans KA25(T) (98.1 %) and clusters with other species of the genus Rhodobacter of the family Rhodobacteraceae. However, DNA-DNA hybridization with Rba. sphaeroides DSM 158(T), Rba. megalophilus JA194(T) and Rba. azotoformans JCM 9340(T) showed relatedness of only 38-57 % with respect to strain JA192(T). On the basis of 16S rRNA gene sequence analysis, DNA-DNA hybridization data and morphological, physiological and chemotaxonomic characters, strain JA192(T) represents a novel species of the genus Rhodobacter, for which the name Rhodobacter johrii sp. nov. is proposed. The type strain is JA192(T) (=DSM 18678(T) =JCM 14543(T) =MTCC 8172(T)).
