- ... The catalytic activity of stem bromelain, covalently immobilized on chitosan beads, was characterized towards a synthetic substrate (Bz-Phe-Val-Arg-pNA), in a wine-like acidic medium containing wine inhibitors (ethanol, sulphur dioxide, grape skin and seed tannins), at their average concentration range.For all tested substances, the inhibition constant (Ki) values of immobilized bromelain were sig ...
