Candida utilis was grown in continuous culturewith decreasing concentrations of phosphate. At a constant dilution rate three successivegrowth patterns were observed: carbon-limited growth, carbon and phosphate dual-limitedgrowth, and phosphate limited growth. Phosphate deficiency as well as phosphatelimitation produced significant modifications In cell composition and morphology,including cell size. At the lowest phosphate concentration (6 mg/P/L), the cellsize was the largest and the relative contents of phosphorus and RNA In the cellswas very low, with 66% of the total phosphorus being located In the RNA fraction.
