Pof yeast strains

WebMay 27, 2024 · Author Information. 1. Introduction. Nowadays, most of the enological fermentations are performed using selected wine yeast strains. Historically, and to some extent to this day, the selected wine yeasts have been found exploring the microbial flora present on the grapes, in the cellar, or in the vineyards. WebThe transformation of a Pof − lager strain with the cloned POF1 gene led to the production of an aroma characteristic of a phenolic off‐flavour, when the transformed strain was used in wort fermentations. This latter observation suggests that the Pof − phenotype of brewers' yeast is specifically due to the absence of a functional POF1 gene.
