Abstract

Summary: Growth conditions (carbon source and pH of the medium) affected the level and distribution of derepressed acid and alkaline phosphatases in . Regardless of the pH, the production of both acid and alkaline phosphatases was stimulated by sucrose. Irrespective of the carbon source used, at pH values higher than 7.4 the secretion of alkaline phosphatase was stimulated, while the production and secretion of acid phosphatase was restricted. The converse was true at pH values lower than 5.7. The secretion of one of these enzymes did not exclude the simultaneous secretion of the other at pH values of around 7.0. These results suggest that the pH of the medium may play an important role in the survival of the organism in phosphorus-limited environments.
