i think its cus the salt concentration will kill the bacteria since its an hypotonic solution, just like for example placing a blood cell on distilled water.

the bacteria will burst and booom!..

well tats wat i think, correct me if im wrong...

Not all saline solution is hypotonic, it depends on the concentration, it could be hypo-, hyper, or iso-

Fresh water is more hypotonic than salty water. So why don't we use that? ;) And bacteria generally have cell walls.

you get it the other way round. salt water is hypertonic, therefore the bacteria will be lose water through osmosis

kiekyon is right, i've read it's really because it's hypertonic.. and cell wall si permeable, so it can not hold water in (isn't it?:P)

I said salt water can be hypotonic, isotonic, or hypertonic depends on its concentration :twisted:

Salty water dehydrates the bacteria.Often salty water in which you can taste the salt is hypertonic compared to the bacterial cell thus exerting an osmotic preesure on the cell.A hypotonic solution relative to that of the bactria is less effective as many bacteria posses cell walls that are similar to those of plants.The bacteria will in such a case become turgid.Turgidity will affect the physiological appearance of the bacteria and will affect its survival and livelihood significantly in quite extreme cases.Thats what I think.
