Hyphomicrobium indicum Johnson and Weisrock 1969 lacks true budding and hyphal branching, and some phenotypic characteristics are in contrast to other true hyphomicrobia. The major quinone system (ubiquinone Q-8), the G+C content of the DNA (40 mol%) and the cellular fatty acid composition (16 : 0, 16 : 1 and 18 : 1 as the major components, and 12 : 0 3-OH and 14 : 0 3-OH as the hydroxy fatty acids) of H. indicum are different from the genus Hyphomicrobium, but similar to the genus Photobacterium. Like the marine bacteria Photobacterium, H. indicum can be tolerant of sea water, while Hyphomicrobium cannot. Phylogenetic analyses of 16S rRNA and gyrB gene sequences revealed that H. indicum is most closely related to the genus Photobacterium of the -Proteobacteria. Based on the phylogenetic, phenotypic and chemotaxonomic evidence, the results indicate that H. indicum should be transferred to the genus Photobacterium, and the name Photobacterium indicum comb. nov. (type strain, NBRC 14233^T=ATCC 19614^T) is proposed.

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence is AB159513 and that for the gyrB sequence is AB159514.
