Abstract
Essential oils (EOs) are one of the most interesting natural products extracted from different aromatic plants. For centuries, EOs have been considered an essential part of the traditional pharmacopeia. Many plant EOs have been reported as possible effective alternatives for commercial pesticides, and their single constituents have been used efficiently in food preservation for their promising anti-QS activity against several food pathogenic microorganisms. The current mini review gives a general overview over the microbicide effect as well as anti-quorum sensing and the anti-biofilm formation of some common plant EOs, especially those of Lamiaceae and Verbanaceae families; these are commonly grown in the Mediterranean region and are effective against some serious food phytopathogenic bacteria.
Highlights
Essential oils (EOs) are considered important natural products extracted from aromatic plants and have been used for centuries in traditional pharmacopeia (Elshafie and Camele, 2017)
One of the most efficient plant EOs, is able to counteract biofilm formation and the quorum sensing (QS) mechanism with its main bioactive constituents, which has explicated a promising effect against different food and human pathogenic bacteria, such as Salmonella enterica subsp. typhimurium and S. aureus (Asfour, 2018)
The biofilm formation of pathogenic bacteria is considered a big challenge for the food industry and human/animal health
Summary
Essential oils (EOs) are considered important natural products extracted from aromatic plants and have been used for centuries in traditional pharmacopeia (Elshafie and Camele, 2017). EOs can be identified as concentrated hydrophobic liquids containing volatile aromatic compounds (Camele et al, 2012; Elshafie et al, 2015b). They have several biological, nutritional, and pharmaceutical properties. Several EOs have demonstrated interesting antimicrobial effects against many serious phytopathogenic fungi and bacteria, both in vitro and in vivo, as well as an effective use in the production of pharmaceutical drugs for plant and human diseases (Mancini et al, 2014; Elshafie and Camele, 2017). Many plant EOs have showed promising anti-biofilm formation and quorum sensing (QS) effects (Poli et al, 2018)
