The major effect of salt as a preservative is that it withdraws water from microorganisms if the external salt concentration is high enough. The microbes would shrivel and die, spores would not be killed but would not be able to germinate. High concentrations of sugar have the same effect. The physical term for this is hypertonic tension. Some bacteria have learned to cope with high salt concentrations and can live in saline waters. Fortunately they are not pathogenic (do not cause disease) so we need not worry about them. I guess de anti Ebola vaccine that i heard was spread in the atmosphere has an effect when in contact on the skin ... Salt in a hot bathing water is only to act as a preservative on the skin, to prevent micro organisms from growing on the external parts of the body... The hot salt bathing water message is in order... #chemicalfield ... Ucikus...
