In homogenates of Tetrahymena pyriformis, five hydrolasesphosphatase, ribonuclease, deoxyribonuclease, proteinase, amylasewith acid pH optima were found. Over 75% of their activity is sedimentable with a centrifugal force of 250,000 g. min. Only 17% of the acid phosphatase and ribonuclease is active
## Abstract __Tetrahymena__ were grown in proteoseβpeptone medium supplemented with glucose, mannose, fructose, galactose, acetate, succinate, or pyruvate and then washed and resuspended in a nonβnutrient salt solution and the amounts of 7 acid hydrolases secreted into the medium in a one hour incu
