Genetic characterisation of New Zealand and Australian wine yeasts
- 39 Downloads
Twenty five culture wine yeast strains from New Zealand and Australia were examined for killer capability or sensitivity. Eight yeast strains were K 2 + killers, six of the K 2 + R 1 - R 3 + phenotype and two of the K 2 + R 1 - R 3 - phenotype. The seventeen sensitive strains were separated into four phenotype classes. The homothallic life cycle was detected in twenty-one strains and one further strain is probably triploid.
