The present results suggest that light emission in luminous bacteria is under the control of at least two genetic factors which, as far as one can tell, do not affect other reactions essential for the growth of the organism. Bacterial luciferase is a flavoprotein which can catalyze the rapid oxidation of reduced pyridine nucleotides by molecular oxygen,2 and it may have figured more prominently in the metabolism of primitive forms of luminous bacteria as well as other organisms. From an evolutionary standpoint it suggests the possibility that these biochemical reactions which support light emission may have had, in the past, some selective advantage for the survival of the organisms.
