Abstract:
Photobacterium leiognathi cultured in marine broth emits a luminescence that is temporarily enhanced and then extinguished by glucose. Glucose reduces the luciferase level and the expression of lux ABG mRNA in P. leiognathi. The amount of ATP in P. leiognathi is temporarily increased and then declines to the normal level. These results indicate that the extinguishing by glucose in P. leiognathi is induced by the interruption of the translation of luciferase.
