In-vitro evaluation of antimicrobial and insect repellent potential of supercritical-carbon dioxide (SCF-CO₂) extracts of selected botanicals against stored product pests and foodborne pathogens.

ABSTRACT: In the present study, the antimicrobial and the insect repellent activity of 16 botanical extracts obtained by supercritical CO₂ (SCF) extraction were evaluated. The present investigation was conducted as there is a necessity for exploration of natural botanical extracts that target both stored product insects and microbes. The antimicrobial activity was studied by disc diffusion and broth microdilution methods against ten microbial species, including Gram-positive bacteria (Staphylococcus aureus, Bacillus subtilis and Listeria monocytogenes), Gram-negative bacteria (Escherichia coli and Salmonella enterica), and fungi (Aspergillus flavus, Aspergillus paraciticus, Aspergillus ochraceous, Aspergillus niger and Penicillium verrucosum).
