Abstract

The bacterium Staphylococcus xylosus and the yeast Candida zeylanoides, originally isolated from dry-cured Chinese Xuanwei ham, were investigated for proteolytic activity towards myofi brillar protein extracts of fresh and salted semimembranosus muscle of pork. Both microorganisms were proteolytically active and caused progressive generation of shorter peptides and free amino acids through the hydrolysis of myofi brillar proteins, which were analyzed by gel electrophoresis (SDS-PAGE)/a highperformance liquid chromatography and an automated amino acid analyzer, respectively. C. zeylanoides had a more pronounced proteolytic activity compared with S. xylosus. Hydrophilic peptides that have been associated with fl avor development were detected in chromatograms of hydrolyzed samples of myofi brillar proteins.
