Bioluminescence is a phenomena in an organism which produces luminescence on quorum sensing and this phenomenon has been explored in many fields like invivo diagnostics, marker technology, protein engineering etc. and has immense potential as future torchlight too with the aid of technologies. Present study aims at the screening and identification of bioluminescent bacteria from different marine sources like fish, lobsters and crabs from the eastern coastal region of India. Total of about 10 different species of fish and some lobsters were screened for their symbiotic bioluminescent bacteria out of these 2 species of fish showed predominant presence of bioluminescent bacteria associated with them, they were namely rani fish and sukum puri. 16srRNA studies revealed bacteria to be belonging to pshychrobacter species associated with Rani fish which has been reported for the first time for showing bioluminescence..The strain sequence has been submitted in NCBI with Accession number LK931862 was named psychrobacter sp.RDP1.
