Mixed fermentation with Metschnikowia pulcherrima using different grape varieties
Duarte, Filomena L.; Egipto, Ricardo; Baleiras-Couto, M. MargaridaThe study and use of non-Saccharomyces yeasts to wine improvement and diversification has gained considerable relevance in recent years. The present work reports a pilot-scale winery assay of mixed fermentation with a commercial strain of Metschnikowia pulcherrima, tested in five white and nine red grape varieties. Two modalities were assayed, one with the addition of M. pulcherrima at time zero and addition of...
Isoenzyme patterns: a valuable molecular tool for the differentiation of Zygosa...
Duarte, Filomena L.; Pais, Célia; Spencer-Martins, Isabel; Leão, CecíliaElectrophoretic analysis of esterase, acid phosphatase, lactate dehydrogenase, glucose-6-phosphate dehydrogenase and alcohol dehydrogenase isoenzymes was performed in 39 strains classified into six species of the yeast genus Zygosaccharomyces. The electrophoretic profiles obtained allowed the clear separation of Z. bailii, Z. bisporus, Z. florentinus, Z. lentus, Z. mellis and Z. rouxii, strains of the latter sp...
