摘要: 本文研究了植物乳杆菌6003活细胞(Cell)、细胞裂解液(Cellextracs,CE)以及两者混合液(Cell+CE)对肌原纤维提取液中的蛋白质的分解作用。通过蛋白质、肽、游离氨基酸分析,表明各实验组对肌原纤维提取液中蛋白、肽分解、游离氨基酸的增加作用较弱,其中Cell+CE组中作用稍为显著,CE组对肌原纤维提取液中蛋白质的分解几乎不起作用。

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.
