Dark-recovery of Gamma- and UV-irradiated Saccharomyces carlsbergensis at 4° C

Experiments were carried out to find the effect of dark-holding in distilled water at 4° C on recovery of Gamma- and UV-irradiated cells of a haploid strain ofSaccharomyces carlsbergensis. It was found that there was an appreciable increase in survival of the irradiated cells following 4 to 24 hours' holding while no increase in the number of “control” cells was observed following similar treatment. It is suggested that some common type of damage induced by both Gamma- and UV-radiations inS. carlsbergensis may be repaired efficiently under metabolic conditions associated with growth at 4° C in distilled water.
