Can yeasts grow food that has a low PH ?
On several occasions , growth of the yeast has been observed in fruit - based alcohols ( pH 2.8 - 3.0 , 40 - 45 % ( w / v ) sucrose ) preserved with 0.08 % ( w / v ) benzoic acid , and in beverages ( pH 3.2 ) containing either 0.06 % ( w / v ) sorbic acid , 0.07 % ( w / v ) benzoic acid , or 2 % ( w / v ) acetic acid .
