Abstract

Summary: O2 affinities of the bioluminescence systems have been measured in five species of luminous bacteria. Photobacterium phosphoreum He-la, recently isolated from a fish light-organ, showed half maximal bioluminescence at 0.015 μm-O2, whereas another symbiotic strain (PJ-1a) gave a 33-fold higher value. Vibrio fischeri MJ-1 gave a value of 0.60μm-O2, and the symbiotic Photobacterium leiognathi LN-1a gave half maximal emission at 0.7μm-O2. These results indicate the importance of strain selection for sensitive O2 measurements.
