These work in a variety of ways to kill off bacteria. One way in which this can be one to cause osmotic lysis:
- Antibiotics can prevent the formation of the proteins for peptide cross linkages in cell walls
- This means that the cell wall which regulates water movement cannot be formed
- As a result, water moves by osmosis into the cell
- Eventually the cell will become too full and burst, this is called osmotic lysis
