Study on the Proteolysis Activities of L．Plantarum 6003 on Muscle Protein (Ⅰ)

Abstract

Abstract: The proteolysis activities of whole cells(Cell), cell extracts (CE) and a combination of both (Cell+CE) of L.plantarum 6003 on muscle sarcoplasmic protein extracts were determined by protein, peptide and free-amino-acid analyses. The results showed that both the cell and Cell+CE could cause the changes of protein, peptides and the increase of free amino acids in the extracts of sarcoplasmic, and that this phenomenon was intensified when the combination of whole cell and CE was involved, whereas the addition of CE had no proteolysis.

Key words: L.plantarum6003, muscle sarcoplasmic protein, proteolysis
