It was found that the supernatants from the digestive tracts of the sea urchins Strongylocentrotus nudus degraded carboxymethyl cellulose, laminaran, fucoidan, microcrystalline cellulose and the crude fiber of Naga-Kombu Laminaria angustata. The degrading activty on sodium alginate could not be detected in the homogenate by measuring an increase of the reducing sugar, but a slight and significant activity was detected by measuring a change of the viscosity.
