In vitro study reveals selective bacteriostatic activity of sweet orange peel essential oil against opportunistic pathogens, suggesting potential utility in natural disinfectant formulations.

Key Points

To identify the chemical composition of Citrus sinensis cv. Thomson Novel peel essential oil and assess its inhibitory potential against opportunistic microbial pathogens.
Extracted essential oil from shade-dried peel waste using Clevenger-type hydrodistillation and identified chemical constituents using gas chromatography-mass spectrometry (GC-MS).
Screened antimicrobial activity against 11 opportunistic microbial strains using agar well diffusion (zone of inhibition) and determined minimum inhibitory and bactericidal/fungicidal concentrations via broth micro-dilution.
GC-MS profiling identified 15 constituents predominantly comprising monoterpene hydrocarbons (75.27%), with D-limonene representing the primary compound at 71.36%.
Agar diffusion screening produced a visible zone of inhibition exclusively against Staphylococcus aureus (9.5 ± 2.12 mm).
Micro-dilution assays showed the highest potency against Acinetobacter baumannii (MIC = 62.5 µg/mL; MBC = 500 µg/mL), demonstrating bacteriostatic action that was significantly weaker than rifampin.
