Abstract This study describes the antibacterial activities of some plant wastes which are rich in bioactive compound such as fruit wastes, medicinal and aromatic plants wastes. Their use as a source of natural antimicrobials may provide alternatives to the food industry as they enable the replacement of synthetic preservatives by natural compounds, as well as the disposal of by-products and reduced environmental impact. Therefore, this study assessed the antimicrobial potential of some agro-industrial wastes against pathogenic microorganisms of importance in foods. About sixteen extracts of different wastes showed antimicrobial activity against Bacillus cereus, E. coli, Salmonella typhimurium, Staphylococcus aureus and Listeria monocytogenes. Extraction was performed using four different solvents for extraction including ethanol 95%, methanol 85%, ethanol : water 50% and commercial hexane at 30°C for 48h. |
