Changes of glucose metabolism during starvation of baker's yeast.Peer-reviewed article

J. PÁCA

The kinetics production, glucose-induced medium acidification and endogenous respiration were studied in baker's yeast starved aerobically for 0, 28, 54 and 96 h in salt solution (9 gper litre NaCl) at35 °C. Except for the last interval, prolonged starvation brought about an overall increase in most parameters. The transient increase in endogenous respiration observed after glucose addition was lowered with proceeding starvation. A 96 h starvation brought about a change in the kinetics of ethanol production, sharp increase in acetate production and a strong reduction of both the extent and the rate of glucose-induced acidification and of endogenous metabolism.
