Duarte, Ricardo Franco; Carrelo, Laura; Dequin, Sylvie; Santos, Manuel A. S.; Casal, Margarida; Schuller, Dorit; Cambon, BrigitteApresentação efetuada no Microbiotec2011, Braga, 2011 ; The use of commercial Saccharomyces cerevisiae wine yeast strains as fermentation starters has been extensively generalised over the past two decades. These strains are used by wineries every harvest time in large quantities. Within our previous work we showed that such strains are disseminated from the winery [1] and their permanence in nature induced ge...
Intra-strain phenotypic and genomic variability of the commercial Saccharomyces...
Duarte, Ricardo Franco; Carreto, Laura; Mendes, Inês; Cambon, Brigitte; Dequin, Sylvie; Santos, Manuel A. S.; Casal, Margarida; Schuller, DoritThe use of commercial Saccharomyces cerevisiae wine strains as fermentation starters has been extensively generalised over the past two decades. These strains are used by wineries every harvest in large quantities. We showed that such strains are disseminated from the winery and their permanence in nature induced genetic changes, not found among a control group of isolates that derived from clonal expansion of ...
The phenotypic landscape of a Saccharomyces cerevisiae strain collection
Mendes, Inês; Duarte, Ricardo Franco; Umek, Lan; Fonseca, Elza; Neves, J. Drumonde; Dequin, Sylvie; Zupan, Blaz; Schuller, DoritWithin our previous work [1] we developed computational models to predict strains with specific phenotypes (e.g. low ethanol resistance, growth at 30ºC and growth in media containing galactose, raffinose or urea) from microsatellite allelic patterns. The objective of the present work was to gain deeper understanding of the phenotypic diversity of a heterogeneous Saccharomyces cerevisiae strain collection, using...

Duarte, Ricardo Franco; Carreto, Laura; Cambon, Brigitte; Dequin, Sylvie; Santos, Manuel A. S.; Casal, Margarida; Schuller, DoritThe use of commercial S. cerevisiae wine strains as fermentation starters has been extensively generalized over the past two decades. Within our previous work we showed that such strains are disseminated from the winery and their permanence in nature induced genetic changes in comparison to the commercial “mother” strain. The objective of the present study was to evaluate genome variations among four isolates o...

Duarte, Ricardo Franco; Carreto, Laura; Cambon, Brigitte; Dequin, Sylvie; Santos, Manuel A. S.; Casal, Margarida; Schuller, DoritApresentação efetuada nas 36.ª Jornadas Portuguesas de Genética, Coimbra, 2011 ; The use of commercial Saccharomyces cerevisiae wine yeast strains as fermentation starters has been extensively generalised over the past two decades. These strains are used by wineries every year at the harvest time in large quantities. Within our previous work we showed that such strains are disseminated from the winery and can ...

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...
