  • Oenococcus oeni is the species of lactic acid bacteria most frequently associated with malolactic fermentation ( MLF ) in wine. Normally, spontaneous MLF takes place when lactic acid bacteria develops in wine after alcoholic fermentation. Several MLST schemes have been described for O. oeni.

Oenococcus oeni is crucial for winemaking, bringing stabilization, deacidification, and sensory impacts through malolactic fermentation (MLF) to most wine styles. The poor nutritional make-up of wine together with typically low processing temperatures and pH and high ethanol content and sulfur dioxide (SO 2 ) hinder O. oeni growth and activity.

O.oeni can decarboxylate L-malate to L (+)-lactate, but cannot use it as a sole source of carbon. It requires the amino acids Glutamic acid, valine, guanine, adenine, xanthine, uracil, riboflavin, folic acid, nicotinic acid, thiamine, biotine and pantothenic acid. There is some variation of amino acid requirement between strains.

Diacetyl in wine is produced by lactic acid bacteria, mainly Oe. oeni. In low levels, it can impart positive nutty or caramel characters, but at levels above 5 mg/l, it creates an intense buttery or butterscotch flavour, where it is perceived as a flaw. The sensory threshold for the compound can vary depending on the levels of certain wine components, such as sulfur dioxide.

Oenococcus oeni is the main lactic acid bacteria species associated with grapes and wine. It is a bacterium that has adapted itself to the harsh conditions of wine, and demonstrated its importance in the production of quality wines. It has a small genome (1.8 Mb); over 200 strains have had their gen … Oenococcus oeni and the genomic era

Oenococcus oeni is a lactic acid bacteria species encountered particularly in wine, where it achieves the malolactic fermentation. Molecular typing methods have previously revealed that the species is made of several genetic groups of strains, some being specific to certain types of wines, ciders or regions.
