Polysaccharidase and glycosidase activities of antarctic krill Euphausia superba.

TLDR: The crude extract of Antarctic krill Euphausia superba contained high activities of galactomannoglycanase, carboxymethyl cellulase, chitinase, amylase and relatively low activities of agarase, mannanase, kappa-carrageenanase and pectinase.

Abstract: The crude extract of Antarctic krill Euphausia superba contained 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 studies on the properties and utilization of these enzymes.
