The study of a strain ofCandida utilis in the course of continuous cultivation on ethanol with special respect to biotin requirement

It was found using a long-term continuous cultivation in a synthetic ethanol medium that a strain ofCandida utilis can permanently form a sufficient amount of growth factors. This fact is confirmed both by high yields of biomass and steady level of biotin in the yeast mass. Composition of proteins is the same as in yeasts grown on other carbon sources.
