YEASTS OCCURRING ON APPLES AND IN APPLE CIDER

Abstract

A study was made of the predominant yeasts that occur on apples grown in Quebec, and in cider. The yeasts isolated from apples were members of the family Cryptococcaceae and of the genera Candida, Cryptococcus, Rhodotorula, and Torulopsis. Species of Candida were by far the most predominant. The yeasts isolated from cider were representatives of the genera Debaryomyces, Pichia, and Saccharomyces. All the yeasts studied were classified into species of the respective genera.
