A collection of indigenous saccharomyces cerevisiae strains from appellations o...
Vieira, E.; Neves, J. Drumonde; Gambon, Brigitte; Valero, Eva; Gomes, Ana Catarina; Sousa, Susana; Lima, Maria Teresa; Araújo, Isabel M.Apresentação efectuada nas "Jornadas Portuguesas de Genética, 35, Braga, 2010" ; The model organism Saccharomyces cerevisiae stands today at the forefront of molecular biology and functional analysis in genetics and genomics. However, understanding of the ecological, evolutionary and population genetic features that shaped the biology of this species is underscored by a wealth of knowledge on molecular and cel...
A Saccharomyces cerevisiae bio-databank for winemaking strain selection
Vieira, E.; Neves, J. Drumonde; Gambon, Brigitte; Valero, Eva; Gomes, Ana Catarina; Sousa, Susana; Lima, Maria Teresa; Araújo, Isabel M.The winemaking industry faces currently an increased demand for novel Saccharomyces cerevisiae strains that are well adapted to different wine styles and that contribute to improved aromatic characteristics. In this reasoning, the Centro de Biologia Molecular e Ambiental (CBMA) at the University of Minho gathered one of the largest bio-databanks of S. cerevisiae, obtained from winemaking environments in Portuga...

Vieira, E.; Neves, J. Drumonde; Gambon, Brigitte; Valero, Eva; Gomes, Ana Catarina; Sousa, Susana; Lima, Maria Teresa; Araújo, Isabel M.Na indústria vitivinícola, verifica-se actualmente uma procura acrescida de novas estirpes de leveduras, adaptadas a diferentes tipos e estilos de vinhos, no sentido da sua diversificação. Neste sentido, o Centro de Biologia Molecular e Ambiental (CBMA) da Universidade do Minho constituiu uma das maiores colecções de estirpes de Saccharomyces cerevisiae, obtidas a partir de ambientes vitivinícolas em Portugal e...

Valero, Eva; Cambon, Brigitte; Schuller, Dorit; Casal, Margarida; Dequin, SylvieProva tipográfica (In Press) ; The use of commercial wine yeast strains as starters has been extensively generalised over the past two decades. In this study, a large scale sampling plan was devised over a period of three years in three different vineyards in the south of France, to evaluate autochthonous wine yeast biodiversity in vineyards around wineries where active dry yeasts have been used as fermentatio...

Valero, Eva; Cambon, Brigitte; Schuller, Dorit; Casal, Margarida; Dequin, SylvieThe use of commercial wine yeast strains as starters has been extensively generalised over the past two decades. In this study, a large scale sampling plan was devised over a period of three years in three different vineyards in the south of France, to evaluate autochthonous wine yeast biodiversity in vineyards around wineries where active dry yeasts have been used as fermentation starters during more than 5 ye...
Comparison of vineyard-associated Saccharomyces cerevisiae populations by micro...
Schuller, Dorit; Valero, Eva; Cambon, Brigitte; Dequin, Sylvie; Casal, MargaridaThe aim of the present study was to evaluate populational structures among fermenting S. cerevisiae populations. Analysis of six polymorphic microsatellite loci was performed in 468 S. cerevisiae isolates derived from a previous screening (using mtDNA RFLP or electrophoretic karyotyoing) of 2490 yeast strains obtained from spontaneous fermentations of grapes collected in three vineyards of the Vinho Verde Regio...
Utilisation de levures sélectionnées et biodiversité
Valero, Eva; Schuller, Dorit; Cambon, Brigitte; Casal, Margarida; Dequin, SylvieTrata-se de uma tradução do artigo "Selected yeast utilization and biodiversity", que foi publicado na revista "Cahier des Entretiens Scientifiques" da empresa multinacional Lallemand. A correspondente comunicacao foi apresentada no âmbito do encontro científico "XVII Entretiens Scientifiques Lallemand" (Logorno, Espanha, 25.4. – 28.4.2005). Cet article a été adapté d’une récente publication, Valero et al., FEM...
Uso dei lieviti selezionati e biodiversità
Valero, Eva; Schuller, Dorit; Cambon, Brigitte; Casal, Margarida; Dequin, SylvieRiassunto Negli ultimi due decenni è stato ampiamente generalizzato l’uso di ceppi commerciali di lieviti enologici come colture starter. I ceppi di lieviti enologici vengono rilasciati ogni anno nell’ambiente attorno agli stabilimenti enologici. Comunque, poco si sa circa il destino di quei ceppi nel vigneto. Per valutare l’abilità dei lieviti industriali, utilizzati come starter, di sopravvivere e diffondersi...
Dissemination and survival of commercial wine yeast in the vineyard : a large-s...
Valero, Eva; Schuller, Dorit; Cambon, Brigitte; Casal, Margarida; Dequin, SylvieProva tipográfica (In Press) ; The use of commercial wine yeast strains as starters has been extensively generalised over the past two decades. In this study, a large-scale sampling plan was devised over a period of three years in six different vineyards to evaluate the dynamics and survival of industrial yeast strains in the vineyard. A total of 198 grape samples were collected at various distances from the w...
