Sulfite is widely used as a preservative in foods and beverages for its antimicrobial antioxidant activities, particularly winemaking where SO2 frequently added. Thus, sulfite resistance mechanisms have been extensively studied the fermenting yeast Saccharomyces cerevisiae. Nevertheless, recent years, negative perception has developed towards sulfites wine, because of human health environmental...

Background: Biosorption plays important roles in the recovery of rare earth metals. The absorption dysprosium (Dy) was tested yeast. Interestingly, brewing yeast, Saccharomyces cerevisiae, showed Dy absorption, and two strains, Alt-OF2 Alt-OF5—previously isolated as highly aluminum-tolerant -absorbing yeast strains—were screened shown to be superior terms their when compared S. cerevisiae. Here...

This research study is to measure the activity of saccharomyces cerevisiae through selected additives which have been added in hydration step making bread dough. The sensitive sugars (Mazzoleni, S. et al.2015) and by using multiple possible that can be found at home, we compare ones give a healthier yeast therefore better rise As ferments, it consumes naturally dough creates an acidic environme...

Adenylosuccinate synthase (EC 6.3.4.4) catalyses the first committed step in the synthesis of adenosine. We have overexpressed the cloned gene of Saccharomyces cerevisiae (ADE12) in S. cerevisiae. The recombinant enzyme exhibits similar kinetic behaviour to that of the native enzyme purified from S. cerevisiae. This ter-reactant dimeric enzyme shows Michaelis-Menten kinetics only with IMP. l-As...

Previous studies reported that the use of Metschnikowia pulcherrima in sequential culture fermentation with Saccharomyces cerevisiae mainly induced a reduction of volatile acidity in wine. The impact of the presence of this yeast on the metabolic pathway involved in pyruvate dehydrogenase (PDH) bypass and glycerol production in S. cerevisiae has never been investigated. In this work, we compare...

Native g2ps1-encoded 2-pyrone synthase (2-PS) from Gerbera hybrida, a mutant Brevibacterium ammoniagenes fatty acid synthase B (FAS-B) and two different mutants of Penicillium patulum 6-methylsalycilic acid synthase (6-MSAS) are examined to identify the best enzyme to recruit for the microbial synthesis of triacetic acid lactone (TAL). To identify the best microbial host for these evaluations, ...

In simultaneous saccharification and fermentation (SSF) for production of cellulosic biofuels, engineered Saccharomyces cerevisiae capable of fermenting cellobiose has provided several benefits, such as lower enzyme costs and faster fermentation rate compared with wild-type S. cerevisiae fermenting glucose. In this study, the effects of an alternative intracellular cellobiose utilization pathwa...

Saccharomyces cerevisiae is increasingly being promoted as a nutritional supplement by health food enthusiasts and is also recommended as prophylaxis against antibiotic-associated diarrhea. However, severe opportunistic infections due to S. cerevisiae have been reported in patients with chronic disease, cancer, and immunosuppression. Fungemia, endocarditis, pneumonia, peritonitis, urinary tract...

The influences of glucose concentration, initial medium acidity (pH), and temperature on the growth and ethanol production of Saccharomyces cerevisiae NK28, which was isolated from kiwi fruit, were examined in shake flask cultures. The optimal glucose concentration, initial medium pH, and temperature for ethanol production were 200 g/l, pH 6.0, and 35oC, respectively. Under this growth conditio...

Saccharomyces cerevisiae HAU-1, a time tested industrial yeast possesses most of the desirable fermentation characteristics like fast growth and fermentation rate, osmotolerance, high ethanol tolerance, ability to ferment molasses, and to ferment at elevated temperatures etc. However, this yeast was found to be sensitive against the killer strains of Saccharomyces cerevisiae. In the present stu...
