Essential Oil of Greek Citrus sinensis cv New Hall - Citrus aurantium Pericarp: Effect upon Cellular Lipid Composition and Growth of Saccharomyces cerevisiae and Antimicrobial Activity against Bacteria, Fungi, and Human Pathogenic Microorganisms

In this study, the essential oil (EO) from peel of Greek citrus hybrid Citrus sinensis cv New Hall - aurantium was studied in terms its antimicrobial properties as well effect on Saccharomyces cerevisiae. According to analysis EO, 48 compounds are contained it, with main being limonene, β-pinene, myrcene, α-pinene, valencene, and α-terpineol. As regards properties, EO evaluated against nine human pathogenic microorganisms, six bacteria, three fungi. Taking results into account, it apparent that Gram-negative bacteria were most susceptible addition followed by Gram-positive finally examined yeasts. The minimum inhibitory concentrations found be lower compared other studies. Finally, biochemical behavior yeast cerevisiae LMBF Y-16 investigated. concentration increased, more exponential phase microbial growth decreased; furthermore, biomass yield glucose consumed significantly decreased medium. small (e.g., 0.3 mL/L) did not present a remarkable negative both final maximum ethanol quantity produced. contrast, utilization extract higher 1.2 noticeably inhibited highest achieved, production, produced per drastically declined. Concerning composition cellular lipids, induced an increment palmitic, stearic, linoleic acids, concomitant decrease palmitoleic acid oleic acids.
