Construction of a Genetically Modified Wine Yeast Strain Expressing the Aspergillus aculeatus rhaA Gene, Encoding an α-l-Rhamnosidase of Enological Interest

摘要

The Aspergillus aculeatus rhaA gene encoding anα -l-rhamnosidase has been expressed in both laboratory and industrial wine yeast strains. Wines produced in microvinifications, conducted using a combination of the genetically modified industrial strain expressing rhaA and another strain expressing a β-glucosidase, show increased content mainly of the aromatic compound linalool.
