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...

an experiment was conducted to assess the influences of different growth promoters on performance, carcass characteristic and intestinal microflora of broiler. day-old broiler chicks from arian strain (384) were used in the completely randomized experimental design during 7-42 days of age. eight rations were formulated as a follow 1: control (without growth promoters); 2-control + formic acid (...

The implementation of biorefineries for a cost-effective and sustainable production energy chemicals from renewable carbon sources plays fundamental role in the transition to circular economy. US Department Energy identified group key target compounds that can be produced biorefinery carbohydrates. In 2010, this list was revised included organic acids (lactic, succinic, levulinic 3-hydroxypropi...

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 ...

Objective: The objective of this study was to examine the toxic and wound-healing behaviours zinc oxide (ZnO) nanoparticles synthesized with an aqueous lysate sourdough (Saccharomyces cerevisiae) on L929 mouse fibroblast cells.Method: Zinc were by microwave method using Saccharomyces cerevisiae. Characterization ZnO accomplished Ultraviolet-Visible region spectroscopy (UV-Vis), SEM Zeta sizer. ...

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...
