RED LIGHT-INDUCED PHOTORECOVERY OF ULTRAVIOLET-B- IRRADIATED YEAST CELLS
Figure 1 - The action spectrum for the photorecovery of UVB-inactivated cells S. cerevisiae
relative activity indicates the efficiency of photorecovery at a certain wavelength in reference to the efficiency at 405 nm (taken as 1). The efficiency of photorecovery at each wavelength in the range 400–750 nm was determined as a reciprocal value of the monochromatic light fluence that increased the survival of the UVB-irradiated cells up to 50%
