Relation between coumarate decarboxylase and vinylphenol reductase activity with regard to the production of volatile phenols by native Dekkera bruxellensis strains under ‘wine-like’ conditions
Sturm, Maria Elena; Assof, Mariela Vanesa; Fanzone, Martín Leandro; Martínez, Claudio; Ganga, M. Angélica; Jofre, Viviana Patricia; Ramirez, María Laura; Combina, Mariana (2015-08)Dekkera/Brettanomyces bruxellensis is considered a major cause of wine spoilage, and 4-ethylphenol and 4-ethylguaiacol are the most abundant off-aromas produced by this species. They are produced by decarboxylation of the ... -
