“…Lemongrass oil demonstrated antibacterial effects against E. coli O157:H7, B. subtilis, S. aureus, S. Typhimurium, and other pathogens (Aiemsaard, Aiumlamai, Aromdee, Taweechaisupapong, & Khunkitti, 2011;Friedman, Henika, Levin, & Mandrell, 2004;Maizura, Fazilah, Norziah, & Karim, 2007). The main composition of lemongrass oil was approximately a or b-citral (73~84%; lemongrass oil-1: 40.80% a-citral & 32.00% b-citral, lemongrass oil-2: 46.05% a-citral & 37.64% b-citral) in this study.…”

“…Other studies suggest that they disturb the cellular membrane and react with active sites of enzymes or act as a H 1 carrier (Ultee et al 2002;Guynot et al 2003). Moreover, the aldehydes may cross-link amino groups in the cell wall and cytoplasm and inhibit enzymes with a thiol group at the cytoplasmic membrane causing coagulation and precipitation of cytoplasmic constituents (Aiemsaard et al 2011). However, knowledge about the antifungal activity of trans-2-hexenal against P. cyclopium is rather limited. Once inside cell, it is a, b-unsaturated aldehyde moiety reacts with biologically important nucleophilic groups (Kubo and Fujita 2001;Lanciotti et al 2004).…”

The study investigated the antifungal activity and potential antifungal mechanisms of volatile compounds (i.e., E‐2‐hexenal) against Penicillium cyclopium, one of the main tomato postharvest pathogens, which was obtained and purified from postharvest tomato surface. Experimental data suggested that the volatile compound exhibited strong antifungal activity against the targeted pathogens, with minimum inhibitory concentration and minimum fungicidal concentration of 160 μL/L and 320μL/L for E‐2‐hexenal, respectively. The membrane permeability of the P. cyclopium increased with increasing concentrations of E‐2‐hexenal, as evidenced by cell constituent release, leakage of potassium ions, and extracellular conductivity. Moreover, E‐2‐hexenal could induce a decrease in total lipid content and extracellular pH. These results suggest that the anti‐fungal activity of E‐2‐hexenal against P. cyclopium can be attributed to the disruption of the cell membrane integrity, the increase of membrane permeability and the leakage of cell components. Practical Applications Penicillium cyclopium was isolated from the surface of tomato fruits after harvest. E‐2‐hexenal had an inhibitory effect on the hyphae and spores of P. cyclopium. The minimum inhibitory concentration and minimum fungicidal concentration were determined by using different concentrations of E‐2‐hexenal against P. cyclopium. The study results indicate that the antifungal activity of E‐2‐hexenal against P. cyclopium can be attributed to the disruption of the cell membrane integrity, the increase of membrane permeability and the leakage of cell components. The study results provided a reference for extending the storage of tomato fruits.

“…Besides, LGO has been reported to have good antibacterial properties [3789]. Evidently, the infection of Gram negative bacteria is hard to treat than Gram positives owing to their intrinsic and acquired resistance mechanisms [22].…”

“…It was identified that lemongrass oil bears antidepressant, antioxidant, antiseptic, sedative, nervine, bactericidal, and fungicidal properties [6]. As a bactericidal agent, the LGO was found to be effective against many bacterial species including Acinetobacter baumanii , Aeromonas veronii , Enterococcus faecalis , Escherichia coli , Klebsiella pneumonia , Salmonella enterica , Serratia marcesens , Proteus vulgaris , Enterobacter aerogenes , Corynebacterium equii , Staphylococcus aureus and so on [3789]. …”

Antimicrobial property of lemongrass (Cymbopogon citratus) oil against pathogenic bacteria isolated from pet turtles

et al. 2017

View full text Add to dashboard Cite

The usage of essential oils as antimicrobial agents is gaining attention. Besides, pet turtles were known to harbor a range of pathogenic bacteria while the turtle keeping is a growing trend worldwide.The current study examined the antimicrobial activity of lemon grass oil (LGO) against seven species of Gram negative bacteria namely; Aeromonas hydrophila, A. caviae, Citrobacter freundii, Salmonella enterica, Edwardsiella tarda, Pseudomonas aeruginosa, and Proteus mirabilis isolated from three popular species of pet turtles. Along with the results of disc diffusion, minimum inhibitory and minimum bactericidal concentration (MIC and MBC) tests, LGO was detected as effective against 6 species of bacteria excluding P. aeruginosa. MIC of LGO for the strains except P. aeruginosa ranged from 0.016 to 0.5% (V/V). The lowest MIC recorded in the E. tarda strain followed by A. hydrophilla, C. freundii, P. mirabilis, and S. enterica. Interestingly, all the bacterial species except E. tarda were showing high multiple antimicrobial resistance (MAR) index values ranging from 0.36 to 0.91 upon the 11 antibiotics tested although they were sensitive to LGO.
