phosphorescence

the emission of light without appreciable heat; it is characterized by the emission of absorbed light after a delay and at a considerably longer wavelength than that of the absorbed light. Caused by a number of bacteria, especially in seawater. One of them, Pseudomonas phosphorescens, may infect coldrooms via infected fish but does not constitute decomposition so that phosphorescent meat is still edible.
