title: [Regularities of posthyperthermic recovery in haploid and diploid yeasts Saccharomyces cerevisiae and Pichia pinus].
abstract: Isogenic diploid cells of Saccharomyces cerevisiae are more sensitive to hyperthermic treatment (50 degrees C) than haploid ones, the posthyperthermical recovery efficiency being the same for both the cell types. In contrast to this, thermosensitivity of haploid and diploid cells of Pichia pinus does not practically differ, the posthyperthermic recovery efficiency for both the cell types being also the same. It is shown that diploid cells of P. pinus in the logarithmic phase of their growth are incapable of recovering after hyperthermal treatment, which is largely the reason for their higher sensitivity to such a treatment as compared with cells in the stationary phase of growth.
