After starvation, yeast exposed to elevated temperatures produced CO2 twice as fast as unexposed organisms. The lag which preceded linear C02 production by starved yeast was essentially eliminated by heat treatment. Uptake and retention of sorbose was greater in heated yeast. Heating was accomplished by brief immersion of the organisms in heated solutions and by growth for 2 h. at 35°. Short heat treatments increased the production of C02 when glucose was included in the suspending medium, whereas heating in water or in growth medium without glucose resulted in a decreased production of CO2.
