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 .
