Action of gamma-irradiated patulin on Saccharomyces cerevisiae.
The action of gamma-irradiated patulin on Saccharomyces cerevisiae LOCK 2144 in liquid culture was studied. Patulin irradiated in an aqueous solution with doses ranging over 0.34-1.36 kGy inhibited the yeast growth in a proportion to the concentration of undestroyed toxin. Patulin disappearance in the growth medium occurred between 12-72 h of incubation at 30 degrees C. The patulin content did not essentially change in the period of log phase of yeast growth which is accompanied by rapid glucose uptake.
