The molecular chaperone Hsp104 is a crucial factor in the acquisition of thermotolerance in yeast. Under stress conditions, the disaggregase activity of Hsp104 facilitates the reactivation of misfolded proteins. Hsp104 is also involved in the propagation of fungal prions. For instance, the well-characterized [PSI(+)] prion of Saccharomyces cerevisiae does not propagate in Deltahsp104 cells or i...

The replication terminator protein Fob1 of Saccharomyces cerevisiae is multifunctional, and it not only promotes polar replication fork arrest at the tandem Ter sites located in the intergenic spacer region of rDNA but also loads the NAD-dependent histone deacetylase Sir2 at Ter sites via a protein complex called RENT (regulator of nucleolar silencing and telophase exit). Sir2 is a component of...

Lipopolysaccharide, known as endotoxin, can stimulate potent host immune responses through the complex of Toll-like-receptor 4 and myeloid differentiation protein 2; but its influence on Saccharomyces cerevisiae, a model organism for studying eukaryotes, is not clear. In this study, we found that lipopolysaccharide-treated S. cerevisiae cells could be stained by methylene blue, but did not die....

A large number of Ca2+ -signaling proteins have been previously identified and characterized in Saccharomyces cerevisiae but relatively few have been discovered in filamentous fungi. In this study, a detailed, comparative genomic analysis of Ca2+ -signaling proteins in Neurospora crassa, Magnaporthe grisea, and S. cerevisiae has been made. Our BLAST analysis identified 48, 42, and 40 Ca2+ -sign...

Saccharomyces cerevisiae is predominantly found in association with human activities, particularly the production of alcoholic beverages. S. paradoxus, the closest known relative of S. cerevisiae, is commonly found on exudates and bark of deciduous trees and in associated soils. This has lead to the idea that S. cerevisiae is a domesticated species, specialized for the fermentation of alcoholic...

Background: Despite the considerable activity of herbal Essential Oils (EOs) as safe food preservatives, problems such as high volatility, low water solubility, and low stability in adverse environmental conditions restrict their use in food products. This work aimed to investigate in vitro antifungal activity of oil-in-water nanoemulsion of Iranian Artemisia dracunculus L. (tarragon) EO. Meth...

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...
