Use of a species-specific multiplex PCR for the identification of pediococci.

2008

In this study, the 23S rRNA genes of nine different Pediococcus type strains were sequenced. By using a multiple sequence alignment with 23S rDNA sequences of related lactic acid bacteria two primer pairs were constructed, one for the general identification of the genus Pediococcus and one for the identification of the atypical species, P. dextrinicus. Furthermore, a primer set for a rapid multiplex PCR identification of the eight typical Pediococcus species was developed. With this technique, the species P. damnosus, P. parvulus, P. inopinatus, P. cellicola, P. pentosaceus, P. acidilactici, P. claussenii, and P. stilesii could be discriminated simultaneously in a single PCR.
