Pediococcus claussenii is a species of Gram-positive bacteria. Like other Pediococcus species, P. claussenii is implicated in the spoilage of fermented beverages{{cite journal|last1=Bergsveinson|first1=Jordyn|last2=Pittet|first2=Vanessa|last3=Ziola|first3=Barry|title=RT-qPCR analysis of putative beer-spoilage gene expression during growth of Lactobacillus brevis BSO 464 and Pediococcus claussenii ATCC BAA-344T in beer|journal=Applied Microbiology and Biotechnology|date=16 August 2012|volume=96|issue=2|pages=461–470|doi=10.1007/s00253-012-4334-3|pmid=22893225|s2cid=16131084}} due to its production of diacetyl. Strains of this species were originally isolated from spoiled beer.{{cite journal|last1=Dobson|first1=C.
