Paper Abstract

The bactericidal effect of visible light illumination on bacteria treated with non-toxic photosensitizers (PS) has been shown previously, its effectiveness depended on both cell type and nature of photosensitizer used. The photosensitizer (PS)-mediated bactericidal effect of light against different types of microorganisms including vegetative bacteria (both in planktonic form and in biofilms), bacterial spores, yeasts, viruses was investigated for both cells in liquid media, and on surface. Bactericidal effect was monitored for different photosensitizer such as TBO and derivatives of rosamine at different concentrations. The possibility of using photodynamic treatment for surface sanitation was investigated.
