Abstract

In this study, the antibacterial activity of Lavandula angustifolia Mill. essential oil obtained from the Güneysınır Agricultural Development Cooperative affiliated with Konya Metropolitan Municipality was investigated against five pathogenic bacterial strains. The antibacterial activity of Lavandula angustifolia essential oil was determined using the disk diffusion method against five standard pathogenic bacterial strains, including two Gram-positive strains (Staphylococcus aureus ATCC 29213 and Streptococcus mutans NCTC 10449) and three Gram-negative strains (Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 29853, and Pseudomonas aeruginosa ATCC 15442). The results demonstrated that Lavandula angustifolia essential oil exhibited varying degrees of antibacterial activity against all bacterial strains tested. The highest antibacterial activity was observed against Escherichia coli ATCC 25922, whereas the lowest activity was observed against Streptococcus mutans NCTC 10449.

Özet

Bu çalışmada, Konya Büyükşehir Belediyesi’ne bağlı Güneysınır Tarımsal Kalkınma Kooperatifi’nden temin edilen Lavandula angustifolia Mill. uçucu yağının beş patojen bakteri suşuna karşı olan antibakteriyel aktivitesinin belirlenmesi amaçlanmıştır. Lavandula angustifolia uçucu yağının iki tanesi Gram-pozitif (Staphylococcus aureus ATCC 29213, Streptococcus mutans NCTC 10449), üç tanesi Gram-negatif (Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 29853, Pseudomonas aeruginosa ATCC 15442) olan beş patojen standart bakteri suşuna karşı olan antibakteriyel aktivitesi disk difüzyon yöntemi ile belirlenmiştir. Çalışmanın sonuçları Lavandula angustifolia uçucu yağının çalışmada kullanılan tüm bakteri suşlarına karşı farklı derecelerde antibakteriyel aktiviteye sahip olduğunu göstermiştir. Lavandula angustifolia uçucu yağı en yüksek antibakteriyel etkiyi Escherichia coli ATCC 25922 suşuna karşı gösterirken, en düşük antibakteriyel etkiyi ise Streptococcus mutans NCTC 10449 suşuna karşı göstermiştir.
