Enhancement of lemongrass essential oil physicochemical properties and antibacterial activity by encapsulation in zein-caseinate nanocomposite.

Essential oils (EOs) represent a pivotal source for developing potent antimicrobial drugs. However, EOs have seldom found their way to the pharmaceutical market due to their instability and low bioavailability. Nanoencapsulation is an auspicious strategy that may circumvent these limitations.

Encapsulation of thymus vulgaris essential oil in caseinate/gelatin nanocomposite hydrogel: In vitro antibacterial activity and in vivo wound healing potential.

Essential oils, derived from aromatic plants, exhibit various pharmacological properties. Nevertheless, their clinical applications are confronted by various limitations, such as chemical instability, low aqueous solubility, and poor bioavailability. Nanoencapsulation is one of the approaches that may circumvent these restraints.

A Probiotic Beverage Made from Tiger-nut Extract and Milk Permeate.

Background And Objective: Tiger-nut has long been recognized for its generous health benefits. Milk permeate as a by-product, contains lactose, soluble vitamins and salts. Probiotics are live micro-organisms that confer a benefit on the host.

Listeria spp. in Street-Vended Ready-to-Eat Foods.

Street-vended ready-to-eat food sold in Egypt, including sandwiches and dishes of traditional food, was examined for the presence of Listeria species. Out of 576 samples, 24% were found to contain Listeria species. L.

Listeria spp. in the coastal environment of the Aqaba Gulf, Suez Gulf and the Red Sea.

Listeria monocytogenes is an important pathogen which causes an infection called listeriosis. Because of the high mortality rate (~30%) associated with listeriosis, and the widespread nature of the organism, it is a major concern for food and water microbiologists since it has been isolated from various types of foods, including seafood, as well as from the aqueous environment. To investigate the prevalence of this pathogen in the Aqaba Gulf (12 sites), Suez Gulf (14 sites) and Red Sea (14 sites), 200 water samples (collected during five sampling cruises in 2004), 40 fresh fish samples and 15 shellfish samples were analysed using the enrichment procedure and selective agar medium.
