Abstract
The pretreatment of Saccharomyces cerevisiae and Debaryomyces vanriji with sodium azide was found to induce thermotolerance in both yeasts, whereas so dium azide used in combination with heat shock enhanced the thermotolerance of S. cerevisiae and substantially decreased the thermotolerance of D. van riji. It is suggested that the different responses of the yeasts to sodium azide during heat shock are due to the different functional organizations o f their mitochondrial apparatus.
