Clostridium butyricum is a kind of anaerobic bacteria, so de-aeration is extremely important during culture. In this paper, adding sodium thiosulfate and cysteine as well as mixed culture with Saccharomyces cerevisiae were adopted in de-aeration during Clostridium butyricum culture. The experimental results showed that the optimal dosage of sodium thiosulfate was 0.004g/mL, where the biomass of...

   In recent science Nanotechnology is a burning field for the researchers. To meet the requirements and growing technological demand, there is a need to develop an eco-friendly approach. In the present effort, the baker’s yeast (Saccharomyces cerevisiae) has been taken in order to assess its potential as putative candidate fungal genera for the transformation of silver nanoparticles. Silve...

zinc (zn) is an essential trace element in all living organisms, and the first eukaryotic zn uptake transporter was discovered in the yeast, saccharomyces cerevisiae. zinc-enriched yeast is a currently available zn supplement. the purpose of the investigation was to compare and evaluate the effect of zn enriched yeast in rainbow trout. the fish (mean body weight 10 ± 0.5 g) were fed a commercia...

berberine was loaded in yeast cells of saccharomyces cerevisiaeas a novel pharmaceutical carrier to improve the treatment ofmany diseases. the yeast-encapsulated active materialsshowedhigh stability and bioavailability due to the enhanced solubility and sustained releasing. in this study, different characteristics of prepared berberine loaded yeast cells (loading capacity, release kinetic order...

Abstract Baker’s yeast Saccharomyces cerevisiae has been used in the production of food and alcoholic beverages since ancient times. In last century it emerged as a leading model organism for studying molecular processes eukaryotic cells, still is very powerful experimental system 21 st biology. The remarkable features this unicellular fungus made its astonishing journey from brewery bakery to ...

Rising sugar content in grape must, and the concomitant increase in alcohol levels in wine, are some of the main challenges affecting the winemaking industry nowadays. Among the several alternative solutions currently under study, the use of non-conventional yeasts during fermentation holds good promise for contributing to relieve this problem. Non-Saccharomyces wine yeast species comprise a hi...

Sugar beet molasses is one of the important by products in sugar industry, it dark brown to black colored and rich source various polysaccharides. So, can be used production ethanol by Saccharomyces cerevisiae. Data showed that 2% inoculums size was best all tested for media. Where alcohol 4.6 ml /100 media with economic coefficient 53.7% yield 46.1%. Also, incubation periods were...

Background: Yeast (Saccharomyces cerevisiae), widely used probiotics, was found to increase the utilization of fiber and improve production in ruminants. The concept chromium (Cr) supplementation has also received a great deal attention since past decade, as Cr could have supra-physiological benefits for domestic livestock. present vitro experiment conducted investigate effect dietary yeast on ...

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...

Saccharomyces cerevisiae has been used for millennia in winemaking, but little is known about the selective forces acting on the wine yeast genome. We sequenced the complete genome of the diploid commercial wine yeast EC1118, resulting in an assembly of 31 scaffolds covering 97% of the S288c reference genome. The wine yeast differed strikingly from the other S. cerevisiae isolates in possessing...
