EFFECT OF PHOSPHORESCENT PARTICLES SUSPENDED IN THE MEDIUM UPON THE EFFICIENCY OF LIGHT-ENERGY UTILIZATION BY CHLORELLA CELLS

Abstract

Using Chlorella ellipsoidea as material, investigations were made to examine whether the rates of growth and photosynthesis of algal cells (in high population densities) could be accelerated by the effect of phosphorescent particles ("copper-activated Zn-Cd-S-phosphor") suspended in the medium. It was revealed that, at least with the experimental arrangement adopted, there was neither accelerating nor suppressing effect attributable to the presence of the substance.
