Abstract

A study was made to determine the amounts of organic acids necessary to inhibit the growths of some yeasts isolated from bottled beverages. It was found that, in a medium containing the same amount of cane sugar used in bottled beverages (10%), with 0.1% peptone as a source of nitrogen and made solid with 2% agar agar, it was necessary to add sufficient acid to give a pH value of 3.3 to 2.6 in order to inhibit the growth of five strains of yeasts of variable sensitiveness. In a similar medium without the agag, acid to give a pH value of 2.7 to 2.3 was required for inhibition of growth.
