EXPERIENCE IN MARINE MICROALGAE METABOLITES USE TO COMBAT PATHOGENIC BIOFILM-FORMING BACTERIA

The effect of marine microalgae metabolites on pathogenic bacteria biofilm-formation on polystyrene was estimated in the paper. Experiments revealed that extracellular compounds Prorocentrum foraminosum PrRUS_7 and Heterosigma akashiwo HAK-SR11 inhibit bacterial growth on polystyrene surfaces. It was also found that Alexandrium affine metabolites stimulated the biofilms development in several cases. By means of scanning electron microscopy it was possible to visualize the effects of inhibition and stimula-tion of pathogen growth manifested by microalgae metabolites. The obtained data can be used for further research in order to create disinfectants for polystyrene materials processing in food production.
