The effect of up to 6,000 Gray (Gy; 1 Gy = 1 J/k) 60Co gamma irradiation on the fermentative capacity of two strains of yeast cells is reported. Ethanol production by the irradiated cells was unchanged for both strains at 3,000 Gy and reduced 43% for only one strain at 6,000 Gy in spite of a marked decrease in viability at higher doses (2-8% at 3,000 Gy and 0.01% at 6,000 Gy). These results suggest that the yeast fermentation system for converting sugar to alcohol is a relatively radioresistant process and not inhibited by the stable by-products produced during irradiation. Furthermore, these data indicate that radiation polymerization for immobilizing these cells should not interfere with their fermentation capacity.
