Abstract: Mechanism of luminescence is a chemical reaction that produces brightness in firely. Living organisms including certain bacteria are capable of luminescence. Bacteria are the most abundant luminescent organisms in nature. Bacterial luminescence is due to the action of the enzyme called luciferase. Other interesting features of marine microorganisms are having their ability to survive at low temperatures and high salinity. The emission of light is a result of the enzymatic activity and biochemical of the living organism (Malave & Orengo et al.,2010). While the luminescence (lux) genes of symbiotic V. fischeri have been shown to be highly induced within the crypts, the role of these genes in the initiation and persistence of the symbiosis. We including genetic elements that allow recombination with the host, the lux DNA can also be integrated into the bacterial genome. Interaction of the two fusion proteins results in energy transfer from the bioluminescent molecule to the fluorescent molecule, with a concomitant change from blue light to green light (Angers et al. 2000). In this review we had discussed Bioluminescence emission of different patterns as flashes (Fireflies, Squids), continuous glow (Bacteria, fungi), blinking (Bacteria), wavy (sea pansy, Renilla), and switched on and off the system (Angler fishes). Although bacterial luciferases, particularly from V. harveyi and X. luminescens, are quite stable the fused luciferase cannot fold efficiently at 37Â°C (Ulitzurs, & Kuhnj, 2006).Bioluminescence property of these different microbes may also be used in different fields also.
