WebUpon addition of D - (+)-glucose (10 mM), this pH value decreased to pH 3.86 ± 0.13 over a period of 10 minutes followed by a gradual rise to a maximal pH of 5.21 ± 0.26, 25 minutes after glucose addition. 45 minutes after the addition of glucose, the intracellular pH of yeast cells returned to that of the glucose starved conditions. WebMay 19, 2024 · Most source water in the U.S. has a pH reading of between 6.5 and 8.5, making it more alkaline than the generally agreed upon optimal mash pH range of 5.2 to 5.8. Yeast grows and multiplies much more rapidly at a pH higher than 5.0 (5.5 is optimal), but fermentation is more efficient if the pH reading is below 5.0.
