Abstract
1. 1. A survey of the carbohydrates present in the digestive tract of Pecten maximus (L.) indicated that the highest enzyme activity occurs in the digestive diverticula. 2. 2. A wide range of di- and tri-saccharides were hydrolysed including cellobiose, sucrose, lactose, maltose, maltotriose and raffinose. 3. 3. The polysaccharides glycogen, starch and laminarin were hydrolysed rapidly but alginic acid, inulin, xylan and chitin were unattacked. Cellulose and pectin were hydrolysed slowly. 4. 4. Fractionation of extracts of the digestive diverticula by chromatofocusing indicated the presence of two ß-glucosidases, two a-glucosidases and four enzymes capable of hydrolysing laminarin. 5. 5. The starch hydrolysing enzyme was characterised as an a-amylase. © 1983.
