Antibiofilm activity of the essential oil of citronella () and its major component, geraniol, on the bacterial biofilms of .

Medicinal plants with antimicrobial action have been investigated for uses against biofilms, among which, , citronella, stands out as a promising species. The present study aims to evaluate the antimicrobial and antibiofilm action of the essential oil of (EOCN) and geraniol on Gram-negative and positive bacteria from the determination of minimum inhibitory concentration (MIC) and minimum bactericidal concentration and inhibition of biofilms. In the results, the EOCN produced a 41 mm halo on , which was susceptible with MIC values of 0.
