method and kit for determining the yeast strain or strains in a sample, method for determining the genetic stability of a yeast strain in a sample, kit for determining the stability of a yeast strain in a sample, composition, method for analyzing a sample containing yeast and probe or primer

摘要

The invention relates to a method of determining the strain or strains of yeast in a sample, comprising: obtaining and screening nucleic acid from yeast for target sequences comprises all or part of a gene, or a flanking region associated with a gene, in the yeast mitochondrial DNA; and determining from the results of the screen the yeast strain or strains in the sample. Also provided is a method of determining the genetic stability of a yeast strain in a sample, wherein one target sequences in the nucleic acid comprises all or part of a gene, or a flanking region associated with a gene, in the yeast mitochondrial DNA or all or part of a gene, or a flanking region associated with a gene, located in the subtelomeric region of a chromosome; and determining from the results of the screen if the yeast strain is genetically stable.
