The quantitative studies with organisms of different complexity (HeLa cells, yeastorganisms, E coli bacteria) to prove or disprove the stimulating action of low-intensityvisible light are presented. The stimulation of DNA synthesis in HeLa cells was observedfor four spectral intervals with maxima at near 400, 620, 680 and 760 nm. The red lightstimulates the growth of yeast (Saccharomycodes ludwigii) and E coli in exponentialgrowth phase. The action spectrum of monochromatic light on the growth of theseorganisms in the red region is very similar to that for HeLa cells.
