[Effect of sodium azide on heat-shock resistance in Saccharomyces cerevisiae and Debaryomyces vanriji yeasts].
The pretreatment of Saccharomyces cerevisiae and Debaryomyces vanriji with sodium azide was found to induce thermotolerance in both yeasts, whereas sodium azide used in combination with heat shock enhanced the thermotolerance of S. cerevisiae and substantially decreased the thermotolerance of D. vanriji. It is suggested that the different responses of the yeasts to sodium azide during heat shock are due to the different functional organizations of their mitochondrial apparatus.
