Most bituminous adhesives or binders that are used for pavement materials are derived primarily from fossil fuels. With petroleum oil reserves becoming depleted and the drive to establish a bio-based economy, there is a push to produce binders from alternative sources, particularly from biorenewable resources. However, until now, no research has studied the applicability of utilizing bio-oils a...

Erucic acid (EA), a fatty acid of 22-carbon chain with one isolated double bond, has broad industrial applications. Currently, erucic acid is isolated from Crucifereae plant oils through steam splitting, namely the Colgate-Emery process, followed by fractional distillation. This two-step process involves drastic conditions, low energy efficiency, and extensive product degradation. Enzymatic app...

This study was aimed at evaluating the capability of Yarrowia lipolytica W29 for the synthesis of lipolytic enzymes in a medium containing plant oils from non-conventional sources with some components displaying bioactivity. Oils from almond, hazelnut, and coriander seeds were obtained by using n-hexane (Soxhlet method) and a chloroform/methanol mixture of solvents (Folch method), and their eff...

the effect of thyme and ajowan essential oils (200µg/l and 300µg/l respectivilly ) on growth of aflatoxin-producing strain of aspergillus parasiticus on 2 stages of pistachio (green and with dry peel ) was studied . also organoleptic tests for evaluating odor and flavor residual of essential oils on pistachio were also performed tested . the collected data were statistically analyzed. the resul...

BACKGROUND In order to find new bioactive natural products, the antimicrobial and antioxidant activities of essential oil components extracted from the separated organs of the Algerian medicinal and aromatic plant Daucus muricatus L. were studied. RESULTS The chemical composition of essential oils obtained by hydrodistillation (HD) was investigated using Gas Chromatography-Retention Indices (...

Growth inhibition of Aspergillus fumigatus,Aspergillus flavus and Fusarum solani exposed to the essential oils including Thyme, Agastache and Satureja were studied. Disc Diffusion Method was used to evaluate the fungal growth inhibitory effects of the essential oils. Minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) of the oils were determined and compared with ...

The antimicrobial activity of essential oils extracted from a variety of aromatic plants, often used in the Portuguese gastronomy was studied in vitro by the agar diffusion method. The essential oils of thyme, oregano, rosemary, verbena, basil, peppermint, pennyroyal and mint were tested against Gram-positive (Listeria monocytogenes, Clostridium perfringens, Bacillus cereus, Staphylococcus aure...

Essential oils are one of the most notorious natural products used for medical purposes. Combined with their popular use in dermatology, their availability, and the development of antimicrobial resistance, commercial essential oils are often an option for therapy. At least 90 essential oils can be identified as being recommended for dermatological use, with at least 1500 combinations. This revi...
