Abstract
Oscillation in bacterial bioluminescence from Photobacterium kishitanii liquid culture was examined regarding reproducibility and bacterial cell activities, i.e., dissolved oxygen (DO) consumption, esterase activity, and product production rate. A frequent increase in DO was suspected to be due to a rapid decrease in luminescence, and a simple model describing not only the monotonous decrease in cell activity, but also the luminescence-DO relationship is proposed.
