Fig. 2. Hydrophobic interaction chromatography (HIC) of the combined and concentrated fractions 37–55 from anion exchange chromatography described in Fig. 1. The concentrate contained endo-β-1,4-glucanase and laminarinase activities and was derived from the midgut gland of G. natalis. Protein content ({square}, mg protein ml–1) and endo-β-1,4-glucanase (•) and laminarinase ({Delta}; µmol reducing sugars or glucose produced min–1 ml–1) activities of the collected fractions.
