Concurrent Effects of High Hydrostatic Pressure, Acidity and Heat on the Destruction and Injury of Yeasts.

Saccharomyces cerevisiae ATCC 2373 and Zygosaccharomyces bailii ATCC 36947 were exposed to hydrostatic pressures ranging from 1,500 to 3,000 atmospheres for 10, 20 and 30 min in 0.1 M citrate buffer at pH 3.0, 4.
