Whey Utilization. V. Growth of Saccharomyces Fragilis in Whey in a Pilot Plant

Abstract

Saccharomyces fragilis was grown in whey medium in a pilot plant study. A flow diagram of the process is given and the equipment described. The oxygen absorption rate (OAR) of the propagator was determined by the sulfite oxidation method. Eighty per cent of the OAR found necessary in the laboratory to supply the oxygen demand of yeast growing under similar conditions could be obtained by modifying the propagator. The yeast yield was 75% of the theoretical value. The dried yeast product is a bland powder with a pleasant, cheese-like flavor.
