A polymerase chain reaction (PCR) method for the detection of Pectinatus ce
revisiiphilus and P. frisingensis was developed. The 16S rRNA gene (rDNA) a
nd the spacer regions between the 16S rDNA and the 23S rDNA genes were used
for the PCR reaction. The species-specific sequences in the spacer region
between the 16S rDNA and the 23S rDNA genes were selected for use as PCR pr
imers. The method developed in this study was rapid and sensitive. Furtherm
ore, this method allowed identification at the species level, even between
very closely related species, such as P. cerevisiiphilus and P. frisingensi
