Abstract

The physiological responses of several polymeric materials and their derivatives, associated with the manufacturing process of pulp, were tested on oysters. It was thought that, when fed in small quantities, these substances might increase shell or meat size or be of value as possible nutritive supplements . The substances tested were divided into two classes. The first, consisting of basic polymeric materials, may occur in natural water s as the result of chemical changes. Representatives of these were indulin C and dextrose. The second class is composed of chemically pure derivatives of the preceding substances. These may appear in trace amounts in natural waters and represent breakdown products of the lignin and carbohydrate substances similar to indulin C and to dextrose. Representatives of this group tested in the following study were glycolic acid, lactic acid, vanillin and catechol.
