Investigating Acid Stress Response in Different Saccharomyces Strains

Table 2

Effect of acid stress on strain viability (% cfu).

Yeast cells were harvested during the exponential growth phase and subjected to 1 h of acidic stress (pH 2.0 + 86 mM NaCl). Data are expressed as the mean ± standard deviations of three separate experiments. *(𝑃 values < 0.05 compared to W303 strain).
