Adhesion of bacteria to wood coatings

Abstract

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.
