This is an important issue, relevant also to the selection and production of furniture, where there is a focus on the development of products with antibacterial surfaces to which microorganisms do not adhere. The focus of our research was to test selected wood coatings (linseed oil, water-borne stain, nitrocellulose varnish, nano-coating) with regard to the adhesion of Pseudomonas aeruginosa, where we used a beech plywood as the test surface. The topography of the test surfaces and the number of adhered bacteria were observed on SEM micrographs. The results indicate that the maximum number of bacteria adhered to the surface coated with linseed oil. In the future, extensive and in-depth studies will be needed to confirm and obtain the required resultsBakterijska adhezija na površinah in pozneje nastanek biofilma predstavljata glavni vzrok kroničnih okužb z negativnim vplivom na zdravje ljudi. S tem izzivom se srečujemo tudi pri izbiri in izdelavi pohištva, kjer stremimo k razvoju izdelkov s takšnimi površinami, na katere naj se bakterije ali drugi mikroorganizmi praviloma ne bi oprijemali. Predmet naše raziskave je bil testirati izbrana premazna sredstva za les (laneno olje, vodna lazura, nitrocelulozni lak, nanopremaz) na adhezijo bakterij vrste Pseudomonas aeruginosa, kjer smo kot testno površino uporabili vezano bukovo ploščo. Topografijo testne površine in število oprijetih bakterij P. aeruginosa smo opazovali z vrstičnim elektronskim mikroskopom (SEM) in na posnetkih SEM identificirali in prešteli bakterije. Rezultati nakazujejo, da se je največje število bakterij oprijelo na površini, premazani z lanenim oljem. Za potrditev in pridobitev relevantnih rezultatov bodo v prihodnosti potrebne obširnejše in bolj poglobljene študijeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza lesarjev Slovenije
