Bacteria cultured from the photophore of a Physiculus spp. fishrecovered from the Arabian Sea produced a distinctive blueluminescence that was brighter than other isolates on laboratory culture. Morphological characterization and biochemicalprofiling suggested that this bacterium belonged to the speciesPhotobacterium phosphoreum, and 16S sequence analysis con-firmed that this isolate was closely related to this species.Analysis of luxA identified only small differences in the genesequence, but the two organisms had different autoinducerprofiles. Spectral analysis confirmed that the luminescence hada different λmax value to that of P. phosphoreum and a novellumP (lumazine) gene was identified. This would account forthe different spectral properties and suggests that this bacteriumrepresents a new subspecies of P. phosphoreum
