ABSTRACT

Yellow-emitting Vibrio fischeri Y1 modulates its bioluminescence (BL) depending on the dissolved O2 concentration. On supplying O2 to the cells under anaerobiosis, the cells begin to emit striking yellow BL peaking around 535 nm. The enhanced yellow emission reverts reversibly to the original level after O2 is consumed. Moreover, the reversible rise and fall of the yellow emission occurs repeatedly in accord with the repeating cycles of aeration on and off. This indicates that...
