Etanol adalah produk yang dihasilkan dari proses fermentasi, etanol dapat dibuat dengan bahan air tebu, nira tebu ataupun mengandung karbohidrat. Pada pandemi covid-19 ini kebutuhan semakin meningkat, banyak digunakan sebagai baku handsanitizer, Bahan parfumed pembuatan kosmetik, dan juga bisa dijadikan bakar. penelitian dilakukan percobaan untuk menghasilkan menggunakan yeast Saccharomyces cer...

Meiotic recombination is a major factor of genome evolution, deeply characterized in only a few model species, notably the yeast Saccharomyces cerevisiae. Consequently, little is known about variations of its properties across species. In this respect, we explored the recombination landscape of Lachancea kluyveri, a protoploid yeast species that diverged from the Saccharomyces genus more than 1...

The selection of yeast strains adapted to fermentation stresses in their winegrowing area is a key factor produce quality wines. Twelve non-Saccharomyces native from Denomination Origin (D.O.) “Vinos de Madrid” (Spain), warm climate region, were tested under osmotic pressure, ethanol, and acidic pH stresses. In addition, mixed combinations between Saccharomyces cerevisiae strain practised. Phen...

Newly made polypeptide chains require the help of molecular chaperones not only to rapidly reach their final three-dimensional forms, but also to unfold and then correctly refold them back to their biologically active form should they misfold. Most prions are an unusual type of protein that can exist in one of two stable conformations, one of which leads to formation of an infectious alternativ...

BACKGROUND The aggregation of the baker's yeast prion Sup35p is at the origin of the transmissible [PSI(+)] trait. We and others have shown that molecular chaperones modulate Sup35p aggregation. However, other protein classes might be involved in [PSI(+)] formation. RESULTS We designed a functional proteomic study that combines two techniques to identify modulators of Sup35p aggregation and d...

Gold standard datasets on protein complexes are key to inferring and validating protein-protein interactions. Despite much progress in characterizing protein complexes in the yeast Saccharomyces cerevisiae, numerous researchers still use as reference the manually curated complexes catalogued by the Munich Information Center of Protein Sequences database. Although this catalogue has served the c...

Yeast species provide excellent models for fundamental biological research. In this review, I will describe characteristics of the two most common laboratory systems: the fission yeast Schizosaccharomyces pombe, and the budding yeast Saccharomyces cerevisiae. They have substantial similarities that make them powerful as research tools, and also striking biological differences that make them com...

Enantioselective production of (S)-2-phenyl-1-propanol is important as in order to be applied industry, a high degree optical purity required. Besides organocatalysts and metal complexes, biocatalysts can used for its synthesis their isolated form or whole-cell biocatalysts, both which have various advantages disadvantages. In this research, Saccharomyces cerevisiae, biocatalyst, recombinant ho...

The study was conducted in Completely Randomized Design with eight treatments replicated three times. were T1 (Indian olive 500 g +250 ml water +150 sugar), T2 +200 T3 T4 +300 T5 sugar +1.5 yeast), T6 T7 yeast) and T8 yeast). Total soluble solids, pH specific gravity decreased while alcohol content, acidity sensory qualities increased increasing length of fermentation. From the above experiment...

Saccharomyces cerevisiae is one of the best-studied model organisms, yet the three-dimensional structure and molecular function of many yeast proteins remain unknown. Yeast proteins were parsed into 14,934 domains, and those lacking sequence similarity to proteins of known structure were folded using the Rosetta de novo structure prediction method on the World Community Grid. This structural da...
