Abstract

Growing evidence suggests that biofilm formation in Pseudomonas aeruginosa (PA) results from quorum sensing, reducing bacterial sensitivity to antibiotics and fostering the development of antibiotic-resistant strains. Addressing the need for a compound that can inhibit quorum sensing signals to mitigate biofilm formation in PA, this study screened 40 essential oils for their potential as quorum sensing inhibitors against PA ATCC9027. Utilizing the agar well diffusion assay, the antibacterial activity of these essential oils was compared with levofloxacin, revealing that 25 out of 40 essential oils exhibited antibacterial activity against PA ATCC9027. The highest antibacterial activity was exhibited by essential oils from Cinnamomum burmannii (Cinnamon Bark Oil), Cananga odorata (Ylang-ylang Oil), and Eucalyptus globulus (Eucalyptus Oil), confirmed by respective MIC values of 0.09765% (v/v), 0.390625% (v/v), and 1.5625% (v/v), and MBC values of 0.09765% (v/v), > 1.5625% (v/v), and > 1.5625% (v/v). Growth curve inhibition assay followed by crystal violet biofilm formation assay revealed that only Ylang-ylang Oil exhibited biofilm formation inhibition at 1/4 MIC concentration. Docking analysis of compounds from these essential oils against quorum sensing enzymes (LasR, PqsR, and QscR) revealed that Ylang-ylang Oil compounds exhibited the highest binding affinity. In conclusion, among the 40 essential oils tested, 25 show potential as antibacterials against PA ATCC9027, with Ylang-ylang Oil standing out as a promising candidate for quorum sensing inhibitor development. The use and development of quorum sensing inhibitors from Ylang-ylang Oil compounds are expected to reduce the burden of antibiotic resistance, especially in Pseudomonas aeruginosa.

Abstract

Kucur Village is a tangerine producer in Malang Regency. However, people still sell it in fresh fruit form; besides that, the pest of fruit flies is also a scourge for farmers, and the absorption capacity in the market for fresh fruit is still relatively lower than the products produced. Processing oranges into secondary products can be a solution for farmers by processing tangerines. Ma Chung University's service aims to develop recipes for making instant powder drinks from tangerines to increase the tangerines' economic value. The method used is recipe development in the laboratory, which is practised in Kucur Village to find which recipe is most suitable and produce products for sale. The results of this service and the Kucur village community produced a recipe suitable for sale as an instant powder drink. The recipe for this instant powder drink contains an infusion of lemongrass stems, ginger, bay leaves, and lime.
