Figure 1. Adjusting synthetic complete medium to a pH of 6.0 extends chronological life span.

Figure 1

Life span extension from buffering at pH 6.0 using a citrate phosphate buffer was statistically significant (p<0.05) in (A) diploid, (B) haploid mating type α, and (C) haploid mating type a of BY4743 (BY) and RM11 (RM). Error bars indicate standard deviation across biological replicates. Corresponding survival integral and p-values are shown in Table 2.
