[ATP content in Candida tropicalis cells growing at different temperatures]

The thermotolerant yeast Candida tropicalis, strain T-20, was cultivated on a chemically defined medium with glucose or malt wort in flasks with shaking at three temperatures: optimal (36degreesC), supraoptimal (38degreesC) and submaximal (41degreesC). An increase of temperature within these limits caused an increase in ATP content in yeast cells and a decrease in phosphohydrolase (ATPase) activity.
