Effect of the He‐Ne LaserRadiation on the ReproductionRate and Protein Synthesis ofthe Yeast

The reproduction rate and protein synthesis of the yeast‐like fungus Endomyces magnusii and yeast Torulopsis sphaerica was studied after the He–Ne laser (λ = 632.8 nm) irradiation. The synthesis of protein in E. magnusii was activated in dose range from 0.42 to 0.84 J/cm2 with maximum at 0.63 J/cm2. In T. sphaerica the maximal activation took place at 0.42 J/cm2. The lag‐period was not changed, but the exponential period of the growth was reduced by 1.5 hours for irradiated cells.
