Yeasts increased rapidly on air-packed irradiated (0.2 and 0.4 megarad) samples of crab meat stored at 0.5 and 5.6°C. The growth of the yeasts on irradiated crab meat was inhibited by vacuum-packing the sample. No appreciable increase in yeast counts occurred on the unirradiated controls. A total of 569 yeast cultures were isolated from unirradiated and irradiated King crab and Dungeness crab meat. The genera represented included Rhodotorula, Cryptococcus, Torulopsis, Candida, Trichosporon, and a yeastlike organism resembling Aureobasidium pullulans. Members of the Cryptococcus, Cnndida, and Aureobasidium pullulans were gelatinolytic and lipolytic. Trichosporon isolates were very active in attacking gelatin, casein, and triglycerides.
