Pediococcus

Abstract Pe.di.o.coc'cus. Gr. n. pedium a plane surface; Gr. n. kokkos a grain or berry; N.L. masc. n. Pediococcus coccus growing in one plane. Nine species are recognized within this genus, including Pediococcus acidilactici (Lindner, 1887; Skerman et al., 1980), Pediococcus claussenii (Dobson et al., 2002), Pediococcus cellicola (Zhang et al., 2005), Pediococcus damnosus (Balcke, 1884; Claussen, 1903; Skerman et al., 1980), Pediococcus dextrinicus (Back, 1978a; Coster and White, 1964; Skerman et al., 1980), Pediococcus inopinatus (Back, 1978a, 1988), Pediococcus parvulus (Günther and White, 1961; Skerman et al., 1980), Pediococcus pentosaceus (Mees, 1934; Skerman et al., 1980) with the subspecies Pediococcus pentosaceus subsp. pentosaceus and Pediococcus pentosaceus subsp. intermedius , and Pediococcus stilesii (Franz et al., 2006). The Pediococcus type species is Pediococcus damnosus (Claussen, 1903). Judicial Opinion 52 states that this generic name is conserved over Pediococcus (Balcke, 1884) and all earlier objective synonyms. Erroneously, the genus name Pediococcus (Balcke, 1884) has been cited in the Approved Lists of Bacterial Names (Skerman, McGowan and Sneath, 1980) and in the Amended Edition of the Approved Lists of Bacterial Names (Euzéby, 1998; Skerman, McGowan and Sneath, 1989). These species can clearly be distinguished on the basis of DNA–DNA similarity (Table 88). DNA G + C content ( mol %): 35–44 ( T m ). Type species : Pediococcus damnosus Claussen 1903, 68 AL . Taxonomic and Nomenclature Notes According to the List of Prokaryotic names with Standing in Nomenclature (LPSN), the taxonomic status of the genus Pediococcus is: correct name (last update, February 2025) * . LPSN classification: Bacteria / Bacillati / Bacillota / Bacilli / Lactobacillales / Lactobacillaceae / Pediococcus The genus Pediococcus can also be recovered in the Genome Taxonomy Database (GTDB) as g__Pediococcus (version v220) ** . GTDB classification: d__Bacteria / p__Bacillota / c__Bacilli / o__Lactobacillales / f__Lactobacillaceae / g__Pediococcus * Meier‐Kolthoff et al. ( 2022 ).
