20.500.12556/RUL-126634 Adhezija bakterij na lesne premaze Adhesion of bacteria to wood coatings Bakterijska 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 študije. Bacterial adhesion to surfaces and subsequent biofilm formation are the main causes of chronic infections with a negative impact on human health, and this is a problem in the process of manufacturing furniture. 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 results. les nanopremaz laneno olje nitrocelulozni lak adhezija bakterij Pseudomonas aeruginosa wood nano-coating linseed oil acrylic stain nitrocellulose lacquer bacterial adhesion true false true Slovenski jezik Angleški jezik Članek v reviji 2021-04-29 11:57:53 2021-04-29 11:58:00 2024-04-03 07:23:29 0000-00-00 00:00:00 2019 0 0 Str. 45-58 št. 2 Letn. 68 dec. 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*829.1:577:539.61 0024-1067 10.26614/les-wood.2019.v68n02a04 3169161 RAZ_Bohinc_Klemen_2019.pdf RAZ_Bohinc_Klemen_2019.pdf 1 0B16690A856A2E92CEA5A36CA2E06E78 ff5a8664d28b57fe6a10c436f00167e57d60a9da017acfa7b4c34268cb13b0e3 b1104f02-a8d1-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142643 https://journals.uni-lj.si/les-wood/article/view/12152 0 5daf6a8f-a8d1-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142642 Biotehniška fakulteta 0 0 0
