Critical assessment of suitable methods used for determination of antibacterial properties at photocatalytic surfaces

Original language description

This work describes the development of methods necessary for antibacterial effect evaluation on irradiated TiO2 layers. Two methods using bacteria suspensions and the glass adhesion method (based on ISO 27447:2009(E)) were critically assessed and compared. As test bacteria gram negative Escherichia coli and gram positive Enterococcus faecalis were employed. The method using 50cm3 of bacteria suspension is convenient for testing layers with strong antibacterial effect (prepared from powder photocatalysts). For the evaluation of the antibacterial effect of sol gel layers, the glass adhesion method based on the ISO is more appropriate than the method with 3cm3 of bacteria suspension. The reason is that the later does not allow a distinction between the inhibition effect of TiO2 and UV light itself. Some improvements of the ISO method were suggested, namely the use of gelatinous pills (CCM) of bacteria, using saline solution instead of nutrient broth for bacteria suspension preparation and
