Figure 1: Apple components can recover premature aging of a yeast early-aging mutant. Cells of strain MCY4/Kllsm4::KanMX4 were grown in synthetic dextrose medium (SD) in the presence of extracts from whole apple, skin, flesh, and polyphenolic fractions. Acetone 7% was used as a control. Viability was monitored as percentage of microcolony forming units (CFU). Standard deviation was obtained from three independent experiments.
