The Aspergillus aculeatus rhaA gene encoding an alpha-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 beta-glucosidase, show. increased content mainly of the aromatic compound linalool.
- microvinification processes
- purifying glycosidases
- grape juice
