Abstract When Candida utilis was grown in continuous culture, decreasing the concentration of N in the medium affected cell composition, biomass yield, biomass productivity, maximal growth rate and cell morphology. When the dilution rate was low (0.1 h-1), reducing N from 1100 to 100 mg/l led to a 40% decrease in RNA content of the cells. Nitrogen-limited growth, which occurred when N〈420 mg/l, was associated with significant changes in cell-wall carbohydrates and a significant reduction in the glycogen content of the cells. A set of culture conditions was established which permitted maximal consumption of the main nutrients in the medium and the production of yeast biomass suitable as a source of single-cell protein.
