ABSTRACTThe crude extract of Antarctic krillEuphausia superbacontained high activities of galactomannoglycanase, carboxymethyl cellulase, chitinase, amylase and relatively low activities of agarase, mannanase, kappa‐carrageenanase and pectinase. The extract also showed high activities of β‐D‐fucosidase, β‐D‐glucosidase, β‐D‐galactosidase and relatively low activities of α‐D‐glucosidase, α‐D‐mannosidase, α‐D‐galactosidase, α‐D‐fucosidase and β‐D‐galacturonidase. The sufficiently high activities of carboxymethyl cellulase, galactomanno‐glycanase, chitinase, β‐D‐fucosidase, β‐D‐glucosidase and β‐D‐galactosidase make krill a potential source for futher
