Assays of hydrolase activity toward the following substrates gave specific activities for Achatina fulicadigestive juice which were within ± 50% of those for Helix pomatiadigestive juice: carboxymethyl cellulose, glycol chitin, laminarin, xylan, glycogen, a glucomannan, gentiobiose, cellobiose, maltose, p-nitrophenol-β-D-glucoside. The specific activities of Achatinadigestive juice were substantially higher than those of Helixfor hydrolase activity towards lichenin, lactose, trehalose, melibiose, and phenolphthalein-β-D-glucuronide and substantially lower for activity towards sucrose, turanose, and p-nitrophenol sulphate. At the same protein concentration, Achatinadigestive juice had greater lytic activity towards Micrococcus lysodeikticus, Bacillus subtilis, Saccharomyces cerevisiae, and Neurospora crassathan Helixdigestive juice. |
