''Pediococcus'' is a genus of [[Gram-positive]] [[lactic acid bacteria]], placed within the family of [[Lactobacillaceae]]. They usually occur in pairs or tetrads, and divide along two planes of symmetry, as do the other lactic acid cocci genera [[Aerococci]] and [[Tetragenococcus]]. They are purely [[homofermentative]]. The genus is paraphyletic and [[Pediococcus dextrinicus]] is only distantly related to any of the other species of the genus.
== Food Processing ==
''Pediococcus'' is, along with other [[lactic acid bacteria]] such as ''[[Leuconostoc]]'' and ''[[Lactobacillus]]'' responsible for the [[fermentation]] of [[cabbage]], making it [[Sauerkraut]].
In this process the sugars in fresh cabbage are transformed to [[lactic acid]]s which give it a sour flavour and good keeping qualities.
''Pediococcus'' bacteria are usually considered contaminants of [[beer]] and [[wine]] although their presence is sometimes desired in beer styles such as [[Lambic]]. Certain ''Pediococcus'' isolates produce [[diacetyl]] which gives a [[butter]]y or [[butterscotch]] aroma to some wines (such as [[Chardonnay]]) and a few styles of beer. ''Pediococcus'' species are often used in [[silage]] inoculants.
