Abstract
Illumination with visible light will induce the recovery or the regaining of viability of u.-v. irradiated conidia of the actinomvcete. S. griseus ATC3326. The light-induced recovery phenomenon is reproduceable and uniform and results in as high as a 400,000-fold increase in number of survivors in an u.-v. irradiated suspension. The characteristics of the phenomenon are described, and its significance discussed.
