Several properties of the probiotic medicinal yeast Saccharomyces boulardii CNCM I-745 contribute to its efficacy to prevent or treat diarrhoea. Besides immunologic effects, pathogen-binding and anti-toxin effects, as well as positive effects on the microbiota, S boulardii CNCM I-745 also has pronounced effects on digestive enzymes of the brush border membrane, known as trophic effects. The lat...

yeasts, especially saccharomyces cerevisiae, are one of the oldest organisms with broad spectrum of applications, owing to their unique genetics and physiology. yeast extract, i.e. the product of yeast cells, is extensively used as nutritional resource in bacterial culture media. the aim of this study was to develop a simple, rapid and cost benefit process to produce the yeast extract. in this ...

methods s. cerevisiae was cultured and then disrupted by sonication. after centrifugation, the harvested supernatant was considered to be a cytoplasmic extract. the protein concentration was determined by the biuret method and the extract was diluted to concentrations of 500, 1000, and 2000 µg protein/ml. the frequencies of apoptosis and necrosis were assessed in extract-treated k562 cells by e...

abstract these days, scientsts search for cheap protein sources because of growthing of population.one of these sources is single cell protein.this study deals with single cell protein production process by saccharomyces cerevisiae and saccharomyces carlsbergensis .these yeast are known as the most ideal and practical eukaryotic microorganism in biological studies. in this survey we added the w...

background and purpose: despite the availability of various treatments for fungal diseases, there are some limitations in the management of these conditions due to multiple treatment-related side-effects. the present study was designed to investigate the antifungal properties of different extracts from pistacia atlantica desf. materials and methods: different parts of p. atlantica (i.e., dried ...

the genome of hb v virus of serotype ayw cloned in pbr322 and expression shuttle vector p yes2 were used for construction of the hbsag chimeric genes and their expression in saccharomyces cerevisiae. two recombinant plasmids were constructed. one of them contained the coding sequences for the major polypeptide of surface antigen. another construct carried the major polypeptide with the pre-s2 a...

BACKGROUND AND OBJECTIVE The efficacy of Saccharomyces boulardii for treatment of childhood diarrhea remains unclear. Our objective was to systematically review data on the effect of S. boulardii on acute childhood diarrhea. METHODS Our data sources included Medline, Embase, CINAHL, Scopus, and The Cochrane Library up to September 2013 without language restrictions. Randomized controlled tria...
