Abstract: Four methods for assessing the antibacterial activity of natural additives with antibacterial properties intended for polymeric materials have been described: in solution, in the form of a film (agar test; bacterial culture test) and in accordance with ISO 22196. Natural additives such as berberine, quercetin, caffeic acid, curcumin and hops were tested in the form of a solution or as an additive to a polymer, i.e. poly(butylene succinate-co-adipate) (PBSA), and their activity was determined against Gram-positive and Gram-negative bacteria – S. aureus and E. coli, respectively. The best results were obtained for additives in the form of a film. On the other hand, the highest antibacterial and biocidal activity was characterized by berberine, caffeic acid and hops.
