Mode of action, mechanisms :
● fast attack bacterial surface
● build on the surface
● Breakdown cell protection wall
● attack bacterial cell membrane
● make cytoplasm outflow of low molecular weight components , such as potassium ions ......
● further decompose the cell membrane , so that the high molecular weight component outflow
● By phospholipids ( nucleic acids present in the cytoplasm ) of the internal components of the role of the cells settle down together .
