Abstract:
Oscillation in the bioluminescent intensity from a luminous bacteria suspension was observed. The time course of the luminescence intensity from a suspension containing luminous bacteria was measured. The oscillation mode changed with the liquid broth component. The optical density and dissolved oxygen (DO) concentration were measured simultaneously with the luminescence intensity, and a possibility was indicated that both diauxic growth and oxygen reaction-consumption resulted with oscillation.
