Özet: Investigations on the development of environmentally friendly, non-toxic products in the antifouling paint technology are becoming more and more widespread. The main purpose of this study is to investigate biocidal activities of fractions belonging to n-BuOH which is one of the polar extracts derived from the plant Erica manipuliflora Salisb. against marine biofilm bacteria, and to carry out a basic research in order to use the extracts determined to have high activity as antifouling agents. Of the fractions belonging to the n-BuOH extract, EBA-EBB-EBC (flavonoids, phenylethanoid glycosides) and EBD-EBE (triterpenoid saponins) were tested against marine biofilm bacteria (Pseudoalteromonas, Alteromonas, Exiguobacterium, Vibrio species) at varying concentrations. Inhibition concentrations of the fractions against marine biofilm bacteria were analyzed with the MIC test and disk diffusion method. As a result of the screening of inhibition concentrations of the n-BuOH fractions obtained from Erica manipuliflora Salisb., the species Alteromonas and Exiguobacterium were determined as the most sensitive bacteria. The fractions EBA, EBD and EBB were more effective. At the end of this study, it was assessed that n-BuOH fractions rich in flavonoids and triterpenoid saponins exhibited activity against some marine biofilm bacteria. It was also determined that it would be worth doing further studies in which pure substances to be obtained could be used as an antifouling additive in industrial areas to prevent marine biofilms.
