Abstract

The rise of antibiotic resistance among pathogenic bacteria has prompted the exploration of alternative antimicrobial agents. Essential oils, known for their potent bioactive properties, have emerged as promising candidates. This study investigates the antibacterial efficacy of essential oils derived from various citrus plants against Aeromonas jandaei, a common pathogen affecting Anabas testudineus. Essential oils from Citrus medica and Citrus aurantium were extracted and characterized using gas chromatography-mass spectrometry (GC-MS). The antibacterial activity was assessed through agar diffusion and broth microdilution methods to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). This study emphasizes the potential of citrus essential oils as effective antibacterial agents against A. jandaei, presenting a natural and sustainable alternative to conventional antibiotics.
