Squalene is a natural dehydrotriterpenic hydrocarbon (C30H50) with six double bonds, known as an intermediate in the biosynthesis of phytosterol or cholesterol in plants or animals. We have briefly reviewed the natural sources for squalene and focused on the main methods and techniques to obtain and to determine it. Some of its applications in different(More)
Boletus edulis is a wild edible mushroom habitually consumed by rural populations. Ethanolic and methanolic extracts was obtained in cold and hot water from dried fruit bodies. The antioxidant activity of freeze-dried extracts from B. edulis were investigated using free radicals scavenging activity, reducing power, metal chelating effect, inhibition of(More)
Phytochemical and antimicrobial screenings of 5 volatile oils of plants (Thymus vulgaris L, Salvia officinalis L, Foeniculum vulgare L., Achillea millefolium L., Carum carvi L.) growing in Southeastern Romanian area were performed. Specific compounds for each species were detected by GC: anethol (80.89% in Foeniculi fructus), carvone (17.37% in Carvi(More)
The modulation potential of the PROBAC product on the simulated microbiota of an infant colon was determined by using the GIS1 single-chamber system of simulation of the human colon. The determination of the viability of each group of microorganisms and of the metabolic activity was performed for each simulated compartment. In order to confirm the(More)
This study aims at obtaining a probiotic product based on viable biomass from 6 yeast strains and 2 strains of lactic bacteria used for nutrition of animals. The strains are subjected to some resistance tests, at temperature, pH, pepsin, pancreatin and biliary salts so as to make obvious their viability. Tests were done by comparison to the witness strain(More)

The biological activity of mushroom consumption is achieved by the antioxidant effect of constituent biomolecules released during digestion. In the following study, the consumption of mushroom fungi was determined to increase the number of Lactobacillus and Bifidobacterium strains within the colon. The main phenolic antioxidant compounds identified were(More)

This study presents the evolution of a Lactobacillus plantarum 2s strain and of a Lactobacillus acidophilus 1a strain on media containing pollen and honey. The following parameters were determined: CFU value, lactic acid production, sugar consumption and presentation of the final product. The researches were performed during 72 h, in tightly closed(More)
