摘要

Most yeasts are traditionally known for ethanol production, which at the same time is a typical antimicrobial compound - a very complex and not fully elucidated interaction. Also, methods and procedures to assess yeast tolerance to ethanol are very diverse (Ross 1987), while data are more or less confined to Saccharomyces cerevisiae. It is well known that metabolic activity of microbes is always associated with heat production (LAMPRECHT and SCHAARSCHMIDT 1977), and changes in this heat evolution dueto inhibitors present in the medium can be quantitatively analyzed. In this work, a calorimetric technique (TAKAHASHI 1990) developed in our research group for the study of microorganism-drug interactions was applied to the study of ethanol inhibition of growth of 9 yeast strains.
