A review on recent research results (2008–2010) on essential oils as antimicrobials and antifungals. A review.

Abstract

The antimicrobial activity of essential oils is discussed in this review taking in account studies which were published in the period of time from 2008 until September 2010. Furthermore, the most important methods to examine the antimicrobial efficiency of essential oils are presented. The studies are divided into the following two groups, namely antibacterial and antifungal active agents depending on the activity of the applied essential oil against the test microorganisms. Various interesting possible applications are revealed such as the use of essential oils instead of synthetic drugs to circumvent the increasing resistance of some pathogens. Moreover, they could not only be used for the therapy of infectious illnesses, but also as preservatives in the food industry. A further possibility is, among others, the application of essential oils in skin products in order to treat or avoid dermal infections. Additionally, the prevalent constituents of the individual antimicrobial active essential oils are elaborated.

Challenges of Sustainable and Commercial Aquaponics

“…In addition to these practices, a few innovative methods of biocontrol already exist for plants cultivated under field or greenhouse conditions. These methods are based on the use of microorganisms with biocontrol activity [85,86], or extracts of such microorganisms or extracts of plants (including essential oils) that show high antimicrobial efficiency and short residence time [87,88]. It will be a challenge to select and adapt these methods to aquaponics systems, considering their compatibility with the other living organisms of the system.…”

Chemical composition of the essential oils and extracts of Achillea species and their biological activities: A review

“…The compositions of the EOs are greatly influenced by diverse parameters involving time and season of harvesting of the plants, type of the plant organs and the corresponding family, geographical and climatic conditions, physiological age, developmental stage, nutritional status of the plants, post-harvest drying, plant storages, genetic diversity, extraction methods, elemental structure of the sampling area, physicochemical variables related to the respective soils and also stress during the growth or maturity (Tabanca et al, 2011;Raut and Karuppayil, 2014;Mohammadhosseini, 2015b, a;Nekoei and Mohammadhosseini, 2016). Some comprehensive reviews covering some important aspects, e.g., the status, preparation methods, biological activities, potential use and processing of the EOs (Radulovic et al, 2007;Bakkali et al, 2008;Nemeth and Bernath, 2008;Adorjan and Buchbauer, 2010;Rubiolo et al, 2010;Lang and Buchbauer, 2012;Shaaban et al, 2012;Tranchida et al, 2012;Oliveira et al, 2014;Raut and Karuppayil, 2014;Sivakumar and Bautista-Banos, 2014;Tongnuanchan and Benjakul, 2014;Xiao et al, 2014;Calo et al, 2015;Herman and Herman, 2015;Zeng et al, 2015;Sarmento-Neto et al, 2016) are available to date.…”

In vitroevaluation of the effects of some plant essential oils onPaenibacillus larvae, the causative agent of American foulbrood

“…The MIC and the minimum bactericidal concentration (MBC) values of these oils were determined using broth microdilution assay and broth macrodilution assay to screen for highly effective, moderately effective, minimally effective and ineffective plant oils. Some of the plant oils tested in this study exhibit antimicrobial activity against various bacterial and fungal pathogens [22,23]; however, little information about their antimicrobial activity against P. larvae has been published. Therefore, this study investigated the activity of 28 different plant EOs against P. larvae.…”
