Published: August 2017

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 genome sequenced. Genomic analyses have proposed that there are two major branches of O. oeni strains that might be linked to wine style (sparkling wine versus white and red) and metagenomic studies have suggested a possible influence of terroir. This review explores recent developments of O. oeni including genomic studies examining O. oeni diversity and how this might shape future regional-specific commercial O. oeni starter strains.

In winemaking, malolactic fermentation (MLF), which converts L-malic acid to L-lactic acid, is often applied after the alcoholic fermentation stage to improve the sensory properties of the wine and its microbiological stability. MLF is usually performed by lactic acid bacteria, which, however, are sensitive to the conditions of alcoholic fermentation. Therefore, the development of wine yeast strains capable of both alcoholic fermentation and MLF is an important task.

Most commercially available red wines undergo alcoholic fermentation by yeasts, followed by a second fermentation with the lactic acid bacteria once the initial process is complete. However, this traditional approach can encounter complications in specific scenarios. These situations pose risks such as stalled alcoholic fermentation or the growth of undesirable bacteria while the process remains incomplete, leaving residual sugars in the wine.

Lactic acid bacteria (LAB), principally Oenococcus oeni, play crucial roles in wine production, contributing to the transformation of L-malic acid into L-lactic acid during malolactic fermentation (MLF). This fermentation is influenced by different factors, including the initial LAB population and wine stress factors, such as nutrient availability. Yeast mannoproteins can enhance LAB survival in wine.

Background: Oenococcus oeni is a commercial wine-fermenting bacterial strain, owing to its high efficiency of malolactic fermentation and stress tolerance. The present study explored the function of key genes in O. oeni to enhance stress resistance by heterologous expression of these genes in another species.

Recently, prokaryotic laccases from lactic acid bacteria (LAB), which can degrade biogenic amines, were discovered. A laccase enzyme has been cloned from , a very important LAB in winemaking, and it has been expressed in . This enzyme has similar characteristics to those previously isolated from LAB as the ability to oxidize canonical substrates such as 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), 2,6-dimethoxyphenol (2,6-DMP), and potassium ferrocyanide K[Fe(CN)], and non-conventional substrates as biogenic amines.
