Patent ID: 6852489

Claim:
A method for classifying a Saccharomyces cerevisiae strain which comprises the following steps: (a) determining the nucleotide sequence of a mitochondrial 21S ribosomal RNA gene of Saccharomyces cerevisiae of interest, and (b) comparing a nucleic acid with each of the positions selected from the group consisting of positions 22 of SEQ ID NO: 18, 186 of SEQ ID NO: 17, SEQ ID NO: 18 or SEQ ID NO: 19, 187 of SEQ ID NO: 17, SEQ ID NO: 18 or SEQ ID NO: 19, 188 of SEQ ID NO: 17, SEQ ID NO: 18 or SEQ ID NO: 19, 407 of SEQ ID NO: 18, 766 of SEQ ID NO: 8, 1170 of SEQ ID NO: 17, 1213 of SEQ ID NO: 17, SEQ ID NO: 18 or SEQ ID NO: 19, 1214 of SEQ ID NO: 17, SEQ ID NO: 18 or SEQ ID NO: 19, 2065 of SEQ ID NO: 17, 2582 of SEQ ID NO: 17, SEQ ID NO: 18 or SEQ ID NO: 19, 2583 of SEQ ID NO: 17, SEQ ID NO: 18 or SEQ ID NO: 19 and 2584 of SEQ ID NO: 17, SEQ ID NO: 18 or SEQ ID NO: 19 with a nucleic acid of the corresponding position(s) in other nucleotide sequences of a mitochondrial 21S ribosomal RNA gene of Saccharomyces cerevisiae; wherein the comparison at position 22 involves an A to G polymorphism; position 186 or 187 involves a deletion of the nucleic acid or T present at each position; position 188 involves a deletion of the nucleic acid or a substitution with an A or T; position 407 involves an A o G polymorphism; position 766 involves a T to A polymorphism; position 1213 involves a deletion of the nucleic acid or T present at the position; position 1214 involves a deletion of nucleic acid or T present at the position; position 2065 involves a C to T polymorphism; and positions 2582, 2583 and 2584 involve a deletion of the nucleic acid or A present at each position.
