Industrial strains of Saccharomyces cerevisiae are genetically
not well characterised and are difficult to identify
unequivocally. A method for yeast identification has
been developed that targets and amplifies delta (δ) sequences.
The δ sequences are direct repeat elements of 0.3
kb with a statistical distribution of about one every 150
kb. It has been shown that this method enabled the identification
of individual strains of Saccharomyces cerevisiae
[7]. PCR using δ sequence primers was reported to
generate characteristic profiles for strain identification of
Saccharomyces cerevisiae. PCR using arbitrary primers
(RAPD PCR) was not able to provide a similar degree of
strain differentiation
