A polymerase chain reaction (PCR) for the detection of beer spoilage bacter
ia was developed. A pre-enrichment step was done with NBB-C. The PCR was pe
rformed with universal primers which amplified the internal transcribed spa
cer region between the 16S rDNA and the 23S rDNA. For further identificatio
n the PCR-product was digested with restriction endonuclease. This method a
ssures a detection of beer spoilage bacteria in the filtrated beer within 4
8 hours.
