''Oenococcus oeni''(also know as ''Leuconostoc oeni'') is a Genus of Gram-positive LAB, ellipsoidal to spherical in shape that is primarily used in Malolactic Fermentation. ''Oenococcus oeni'' is a facultative anaerobe. It is able to use oxygen for cellular respiration but can also gain energy through fermentation. It characteristically grows well in the environments of wine, being able to survive in acidic conditions below pH 3.0 and tolerant of ethanol levels above 10%. Optimal growth occurs on sugar and protein rich media. Cells tend to grow in chains or pairs. ''O. Oeni'' is heterofermentative and generally produces CO2, Ethanol, Acetate, and Diacetyl. <ref name="MicrobeWikiOO">[https://microbewiki.kenyon.edu/index.php/Oenococcus_oeni "Oenococcus oeni".
