Effect of citronella oil on time kill profile, leakage and morphological changes of propionibacterium acnes / Pilanthana Lertsatitthanakorn in The journal of essential oil research, Vol. 22 N° 3 (Mai/Juin 2010)

Citronella oil compositions were determined by gas chromatography mass spectrometry (GC/MS). Anti-P. acnes activity of citronella oil and its major components were also investigated. After exposure with P. acnes at various concentrations of citronella oil (0–100 mL/mL), time-kill profiles, pentose leakage and electron microscopic characteristics were determined. The GC/MS results revealed that the major constituents of the oil were citronellal, geraniol and citronellol. At all concentrations above Minimum Bactericidal Concentrations (MBCs; 0.625mL/mL), this essential oil killed P. acnes in a dose-dependent manner. The intracellular materials leakage and electron microscopic characteristics evidenced that the major target sites of antibacterial activity appeared to be cell wall, cytoplasmic membrane and intracellular materials. Citronella oil exerted satisfactory bacteriostatic and bactericidal actions against P. acnes.
