Study on Proteolysis Activities of L.plantarum 6003 on Muscle Protein Extracts

Abstract

Abstract: The proteolysis activities on muscle myofibrilliar protein extract s of whole cells, cell extracts (CE) or a combination of both (Cell+CE), of L.pla ntarum 6003 were determined by protein, peptide and free-amino-acid analyses. All treatments caused weak changes of protein, peptides and the increase of free amino acids in the extracts of myofibrilliar.These changes were rather sign ificant when the combination of whole cell and CE was involved. However the add ition of CE alone had almost no proteolysis.

Key words: L plantarum 6003, muscle myofibrilliar protein, proteolysis
