Abstract
DNA sequences are provided which are useful in identifying different fermentation-related microorganisms, such as those involved in fermentations. These DNA sequences can be used to provide oligonucleotide primers in PCR based analysis for the identification of fermentation-related microorganisms. The DNA sequences of the present invention include the internal transcribed spacer (ITS) of the ribosomal RNA gene regions of particular fermentation-related microorganisms, as well as oligonucleotide primers which are derived from these regions which are capable of identifying the particular microorganism.
