Proteolytic activity from chicken intestine and pancreas: extraction, partial characterization and application for hyaluronic acid separation from chicken comb

“…), indicating the presence of both neutral and slightly alkaline proteases. This finding is consistent with previous reports on various proteases extracted from poultry intestine and pancreas, including aminopeptidase (optimal pH 6–7.5), carboxypeptidase B (optimal pH 8) and trypsin and chymotrypsin (optimal pH 7.5) …”
