| Résumé : |
To prevent losses caused by microbiological decay of leathers during technological processing, biocidal and biostatic chemical agents are used. They are introduced into the material structure at various stages of the tanning process. It has been shown that some of these agents are not neutral to human health and to the environment. Thus, substitutes for chemical preparations of appropriate efficiency in control of bacteria and fungi, but being safe to humans and the environment are sought. Suitability has been adequately confirmed by research performed worldwide on essential oils. In this paper antimicrobial resistance of lining leathers protected with essential oils extracted from plants Cinnamomum verum, Eucalyptus globulus, Origanum vulgare, Leptospermum scoparium and Thymus vulgaris is investigated. They were introduced into the leather at the fatliquoring stage at 5% per weight of leather. Antimicrobial activity of samples oiled with essential oils and controls (without these oils) was evaluated against bacteria Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and yeasts Candida albicans after 1 and 6 months. The growth inhibition zone around leather samples and microorganism growth, or lack of growth, within the sample-medium contact zone was determined. Investigations have confirmed the efficiency of three of five proposed oils: oregano, cinnamon and thyme. The strongest and most longlasting antimicrobial activity was observed for leathers preserved with oregano oil. Insufficient effect was found for leathers oiled with manuka and eucalyptus oils. |
