Abstract
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.
