Tolerance to winemaking stress conditions of Patagonian strains of Saccharomyces eubayanus and Saccharomyces uvarum
(Wiley Blackwell Publishing, Inc, 2017-08)
Aims: Evaluating the winemaking stress tolerance of a set of both Saccharomyces eubayanus and Saccharomyces uvarum strains from diverse Patagonian habitats. Methods and Results: Yeast strains growth was analysed under ...
The genome sequence of Saccharomyces Eubayanus and the domestication of Lager-Brewing yeasts
(Oxford University Press, 2015-08)
The dramatic phenotypic changes that occur in organisms during domestication leave indelible imprints on their genomes. Although many domesticated plants and animals have been systematically compared with their wild genetic ...
Fermentative behaviour and competition capacity of cryotolerant Saccharomyces species in different nitrogen conditions
(Elsevier Science, 2019-02-16)
The selection of yeasts with low nitrogen requirement is a current need in winemaking. In this work, we analysed nitrogen requirements of strains belonging to the cryotolerant species S. uvarum, S. eubayanus and S. ...
Production of a novel killer toxin from Saccharomyces eubayanus using agro-industrial waste and its application against wine spoilage yeasts
(Springer, 2019-01)
The juicing industry generates large amounts of waste that mostly lack commercial value and, in the absence of waste treatment policies, produces environmental pollution. Also, microbiological spoilage is a major concern ...
Phylogeography of the wild Lager-brewing ancestor (Saccharomyces eubayanus) in Patagonia
(Wiley Blackwell Publishing, Inc, 2018-10)
Saccharomyces eubayanus is the close relative of the Lager-brewing yeast and was firstly found in North Patagonia associated with Nothofagus trees. In recent years additional strains were found in North America, Asia and ...
Purification and characterization of Saccharomyces eubayanus killer toxin: Biocontrol effectiveness against wine spoilage yeasts
(Elsevier B.V., 2020-10)
Microbiological contamination by spoilage yeasts species are frequent during winemaking, and biological control using antagonistic yeasts is considered a more beneficial alternative to conventional synthetic antimicrobials. ...
Saccharomyces eubayanus and Saccharomyces uvarum associated with the fermentation of Araucaria araucana seeds in Patagonia
(Oxford University Press, 2014-07)
Mudai is a traditional fermented beverage, made from the seeds of the Araucaria araucana tree by Mapuche communities. The main goal of the present study was to identify and characterize the yeast microbiota responsible of ...
Physiological characterization of Saccharomyces uvarum and Saccharomyces eubayanus from Patagonia and their potential for cidermaking
(Elsevier Science, 2017-05)
A diversity of yeast strains belonging to the cryotolerant fermentative species S. uvarum and S. eubayanus have been recovered from natural habitats and traditional fermentations in North Patagonia. The aim of this work ...
On the Complexity of the Saccharomyces bayanus Taxon: Hybridization and Potential Hybrid Speciation
(Public Library of Science, 2014-04)
Although the genus Saccharomyces has been thoroughly studied, some species in the genus has not yet been accurately resolved; an example is S. bayanus, a taxon that includes genetically diverse lineages of pure and hybrid ...
