Three types of packaging papers (bleached, unbleached, and recycled) are treated with an essential oil and then stored for 2 h, 24 h, and 5 days. The antibacterial activity of coriander oil is tested against Gram-positive bacteria (Staphylococcus aureus ATCC 6538 and Bacillus subtilis ATCC 6633); Gram-negative bacteria (Escherichia coli ATCC 8739, Pseudomonas aeruginosa ATCC 9027, and Salmonella abony NTCC 6017); an yeast (Candida albicans ATCC 10231), and a fungal strain (Aspergillus brasiliensis ATCC 16404). Ahigh fungicidal potential is observed in case of all packaging materials. The antimicrobial action of the bleached paper coated with coriander oil against Gram-positive bacteria during the five-day storage period decreases slightly from 100 % - 94 % to 79 % - 81 %.enArticle
