1.1.The activity of the following digestive enzymes: α-glucosidase, β-glucosidase, α-galactosidase, β-galactosidase, α-mannosidase, β-glucuronidase, β-xylosidase, β-fucosidase, non-specific esterase, lipase, exopeptidase and endopeptidase were investigated and localized in the gut of Neanthes virens (Sars).2.2.Enzyme activity was estimated using both histochemical and biochemical techniques, and
... [Show full abstract] the main sites of production of extracellular digestive enzymes were shown to be the oesophageal pouches and the anterior parts of the intestine.
