<p>Cells were aged in synthetic complete medium supplemented with the appropriate carbon source and pH measurements were taken at both day 2 and day 4 of the experiment. Control concentrations for all carbon sources were tested at 2% w/v, except ethanol and glycerol which were tested at 3%. Moderate dietary restriction (DR) concentrations were at 0.5% for all sources except ethanol and glycerol, which were reduced to 1%. Survival integral (SI) values represent the area under the survival curve between day 2 and day 26.</p><p>*Denotes a statistically significant increase SI in response to DR (p<0.05).</p
