[Comparison of the zymograms of isopod (Crustacea, Peracarides) digestive tubes].
The zymograms of the digestive caeca and the intestine in seven species of Isopods are established. The glucidasic activities predominate. A relative proteasic poverty is noted as well as the absence of lipases however, the esterases exist. The enzymatic pattern of the gut suggests its participation in the alimentary digestion. The enzymes distribution allows us to establish relations with the food preference of the animals. Some particularities (trypsin, alpha and beta glucosidase) favour a comparison of the marine species with the supralittoral species on one hand and with terrestrial species on the other. This fact does not exclude however the systematic interest of the zymograms.
