Pediococcus is a genus of gram-positive lactic acid bacteria within the family Lactobacillaceae. These bacteria typically occur in pairs or tetrads and divide along two planes of symmetry. Similar division patterns are observed in other lactic acid cocci genera like Aerococcus and Tetragenococcus. Pediococci are purely homofermentative 1. Here are some interesting facts about Pediococcus: Food Processing: Pediococcus plays a crucial role in the fermentation of cabbage, contributing to the creation of sauerkraut. During this process, the sugars in fresh cabbage are converted to lactic acid, giving sauerkraut its characteristic sour flavor and enhancing its shelf life. Beer and Wine: While Pediococcus is often considered a contaminant in beer and wine, its presence is intentionally desired in certain beer styles such as lambic and Berliner Weisse. Some Pediococcus isolates produce diacetyl, which imparts a buttery or butterscotch aroma to specific wines (like Chardonnay) and beer styles. Silage Inoculants: Pediococcus species find application in silage inoculants, aiding in the preservation of animal feed. Probiotics and Food Production: Pediococci are used as probiotics and are commonly added to create sausages, cheeses, and yogurts.
