Summary Taking advantage of a synthetic nutrient medium, we have studied which compounds phosphate-starvedTetrahymena thermophila can use as phosphate sources for growth and cell multiplication. Ortho-, trimeta- and α-glycero-phosphate are good sources for both the wild type and a food-vacuoleless mutant; phosphorylcholine is used only by the wild type, and 2-aminoethyl phosphonic acid fails to serve as a phosphate source. Since at least two phosphatases are found in the extracellular fluid these results indicate thatTetrahymena can make use of extracellular digestion of nutrients.
