How does salt kill bacteria

Salt kills some types of bacteria, effectively by sucking water out of them. In a process known as osmosis, water passes out of a bacterium so as to balance salt concentrations on each side of its cell membrane. ... These pathogens have a salt alert system that uses sponge-like molecules to prevent water loss.
