Abstract : Bioluminescence is the light radiated as a result of a chemical reaction within a living organism. The objective of this effort was to perform experimental studies to quantify the light emission from a typical dinoflagellate (Gonyaulax polyedra) as a function of the emission producing stimulus. It was observed that for completely turbulent pipe flow a linear relationship exists between wall shear and stimulated light emission. Experiments performed with a plane acoustic wave showed that light emission appears to be more pressure dependent than frequency dependent. It was observed that natural recovery of stimulable emission is preferable to attempts to optically 'pump' the Gonyaulax to a higher level of light emission. The effect of monochromatic light at 488 nm appears to inhibit stimulable emission in the Gonyaulax. (Modified author abstract)
