Influence of air-ions on selected microorganisms

In the following work the influence of air-ions and ozone on the selected microorganisms, first of all on Staphylococcus epidermidis is discussed. Carried out investigations proved that the levels of air-ions concentrations, causing specific changes in the development of particular microorganisms, are very differentiated and depend on individual parameters of those organisms. These levels are generally characterized by high values of concentrations, range n +/- =4 x 10(6) ions/cm3 and are connected with the type of the air-ions used. However investigations did not confirm any negative influence of the positive air-ions seen as a destructive factor upon any of the investigated microorganisms.
