Résumé :

In a standard growing medium, the specific activities of acid-phosphatase, βgalactosidase and βglucosidase of Physarum polycephalum increase during the growth of the culture. The decrease of the pH of the culture medium during the growth has no effect on the variations of these hydrolase activities. In a glucose-starved medium, the specific activity of βgalactosidase increases up to 350 % of its initial value in 24 h, whereas the specific activities of acid phosphatase and βglucosidase stay near their minimal level. © 1980 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
