Abstract
There is described a method for assaying for loss of viability of a photosynthetic organism (preferably a microorganism) in an aqueous liquid. In a preferred embodiment, the method comprises the step of using fluorescence to correlate the photorepair index for the organism in the aqueous liquid to survivorship of the organism (preferably a microorganism) after it is exposed to ultraviolet radiation, thereby assessing viability.

A method for assaying for loss of viability of an organism in an aqueous liquid after the organism has been exposed to a stressor, the method comprising the step of correlating the photorepair index for the organism in the aqueous liquid to survivorship of the organism after the organism has been exposed to the stressor.
25-33. (canceled)
A method for assaying for loss of viability of an organism comprised in an aqueous liquid after the organism has been exposed to a stressor, the method comprising the steps of:
- (a) measuring the variable fluorescence (Fv) of an untreated sample of the organism prior to exposure to the stressor;
- (b) measuring the variable fluorescence (Fv) of a treated sample of the organism after exposure to the stressor;
- (c) calculating a photorepair index using the measurements obtained in Steps (a) and (b);
- and
- (d) correlating the photorepair index calculated in Step (c) to a normalized viability for the organism.
