Opis:
The paper covered with a hydrophobic Topscreen coating was coated with the second layer. The goal of paper covering was to obtain the antimicrobial properties of the external coating. The samples were stored 2 months at 20 ºC. The influence of storage on the antimicrobial properties of the external coating was analyzed. The results of the study showed that paper covered with Topscreen coating did not have an influence on the growth of Staphylococcus aureus cells. The second (external) layer containing 2% polylysine as an active substance decreased the growth of S. aureus. The 2 months storage of the covered paper did not influence the antimicrobial properties of coating with polylysine against S. aureus. It was demonstrated that paper covered with hydrophobic coating had no influence on the growth of E. coli cells as well. In this case the influence of 2 months storage on the antimicrobial properties of the coating with polylysine was observed. In contrast to the results obtained for the samples that were not store, the decrease of the growth of the bacterial cells after 24 h contact with a hydrophobic coating devoid of an active substance was noticed.

Opis:
The purpose of the research work was to examine the antifungal properties of cumin, rosemary and fennel essential oils. The goal of the study was also to determine antifungal activity of coatings containing the essential oils. The results of the study demonstrated that cumin, rosemary and fennel essential oils exhibited antifungal properties. The most sensitive strains were Botrytis cinerea and Mucor circinelloides. The cumin oil was found to be the most active. The growth of Botrytis cinerea and Mucor circinelloides was not observed even on medium containing 0.1% of cumin oil. The growth of Aspergillus niger, Aspergillus clavatus and Rhizopus oryzae was not noticed on mediums containig 0.5% of the oil. The similar results were obtained for fennel essential oil. 0.5% concentration of the oil in medium inhibited the growth of Botrytis cinerea, Mucor circinelloides, Aspergillus clavatus, Rhizopus oryzae. The rosemary oil did not inhibited the growth of fungi strains in concentration of 0,1%.
