The pollens ofApiaceae, Asteraceae, Betulaceae, Boraginaceae, Brassicaceae, Campanulaceae, Caryophyllaceae,Fabaceae, Fagacee, Lamiaceae, Poaceae, Pinaceae, Ranunculaceae, Rosaceae, Salicaceae andScrophulariaceae taxa were found in the palynological analysis. Gram negative and Gram positivebacteria were used to determine in vitro antibacterial activities of the propolis samples. The most potentinhibitory effect against the target microorganisms was obtained from IP1. The most resistant strains wereBurkholderia cepacia, Citrobacter freundii and Streptococcus pneumoniae for all the propolis samples.But, the antibacterial activity levels of the samples were different from each other. These results indicatethat propolis can be assessed in different areas such as cosmetic, medicine and food as an antimicrobialagent.eninfo:eu-repo/semantics/openAccessArticle16214314810.18466/cbayarfbe.687098374799
