The Antimicrobial Activity of Citrus aurantium Amara

Abstract

Citrus aurantium L. is an evergreen tree that can reach a height of up to five metres. It is also referred to as bigarade, bitter orange, sour orange, and Seville orange. A number of studies have been carried out on the bioactivity of substances extracted from C. aurantium. Plant disease-causing bacteria also have a significant financial impact. Plant pathogenic bacteria can occur both inside plants as pathogens and outside plants as saprophytes in a variety of environments. The main objective of this paper is to assess the antibacterial efficacy of C. aurantium essential oil against five plant bacterial pathogens both in vitro and in situ. C. aurantium essential oil (EO) has the potential to be used in various food applications due to its natural antibacterial properties. Using the disc diffusion method, we found the best antimicrobial potential against Pectobacterium carotovorum. Using vapor phase antimicrobial activity on carrot model, the best microbial activity was found against Xanthomonas arboricola bacteria. The results of the antibacterial test showed that EO exhibited antibacterial effect against each bacteria tested.
