Abstract
The aim of the current work is the comparison of the ozone, ozone/UV, UV and UV/VU V induced destruction of a spore-former (Bacillus megaterium), a Gram positive (Micrococcus luteus) and a Gram negative (Serratia marcesens) bacterium in the presence of a model food component carbohydrate lactose, and carbohydrate and protein containing solution. In "clear" solutions both method was sufficient to achieve 1 or in most cases min. 2 order of magnitudes decrease of microorganisms. The Gram negative Serratia marcesens appeared to be the most sensitive, while the Bacillus megaterium and Micrococcus luteus were more resistant to the treatments. The presence of organic matter had affected to disinfecting efficiency of all methods in the case of all microorganism, but the effect depends on the type of the substrate. In the presence of protein and carbohydrate containing solution the situation is markedly different. It was found that lactose inhibits the disinfection, while protein increase the disinfection efficiency which can be explained by the formation of toxic degradation products derived from proteins.
