Studies on the metabolism of Echinococcus granulosus. II. Some observations on the carbohydrate metabolism of hydatid cyst scolices

Abstract

1. 1. Intracellular glycogen disappears upon incubation under aerobic and anaerobic conditions, 11.97 μmoles and 13.50 μmoles/gram fresh tissue/three hours being consumed respectively. 2. 2. Under aerobic conditions, glycogen is converted to a mixture of lactic, acetic, succinic, and pyruvic acids, and ethyl alcohol. From a quantitative standpoint, lactic acid was the most important endproduct. 3. 3. Under anaerobic conditions, glycogen is fermented to a mixture of lactic, succinic, and acetic acids, as well as ethyl alcohol. No α-ketoacids are produced; lactic and succinic acids are quantitatively the most important endproducts.
