Abstract

The obligately psychrophilic yeast, Leucosporidium stokesii increased in size, produced irregular wall growth and formed atypical buds when incubated within one to three degrees above 20 °C, the maximum growth temperature. Incubation of cells anaerobically or aerobically in the presence of 2,4-dinitrophenol at the elevated temperatures prevented the development of atypical buds. An investigation of subcellular morphology revealed that the atypical bud was anucleate, did not form a septum between bud and parent cell and produced numerous cytoplasmic vesicles. On shift-down to 15 °C, the optimum growth temperature, nuclear division, migration and septum formation resumed.
