Abstract :The essential oil derived from Laurus nobilis exhibits a high concentration of bioactive components, imparting various therapeutic characteristics. This study aimed to analyze the chemical composition of the essential oil extracted from Laurus nobilis leaves as well as its biological properties, including its antipseudomonal and antibiofilm actions. Gas chromatography-mass spectrometry (GC-MS) analysis revealed that 1,8-cineole (%48.43) and α-terpinyl acetate (14.78) were the major compounds present in the essential oil (EO). While, the minimum inhibitory concentration (MIC) values of Laurus nobilis essential oils (LEO) against P. fluorescens and P. putida were determined as 31.25 µg/mL, it was 62.5 µg/mL for P. aeruginosa. LEO, at a MIC level of 31,25µg/mL, exhibited significant inhibition of Pseudomonas species biofilm formation except for P. aeruginosa. Based on its demonstrated antibacterial and antibiofilm potential, LEO holds promise as a prospective source of antibacterial agents.Keywords : antibakteriyel aktivite, antibiyofilm aktivite, uçucu yağ, defne
