In contrast, greater strain identity was seen for cider, white wine, or red wine of Burgundy, suggesting that genetic adaptation to these products occurred. The second beneficial factor that O. oeni has is its ability to tolerate low pH levels that go along with standard alcohol levels for most wines. Learn more. (A) A neighbor-joining tree was constructed using the 43 different concatenated sequences of SNP identified by analyzing 577 O. oeni strains. 2018 Feb 14;9:90. doi: 10.3389/fmicb.2018.00090. Abstract Background: Oenococcus oeni is a lactic acid bacterium that is specialised for growth in the ecological niche of wine, where it is noted for its ability to perform the secondary, malolactic fermentation that is often required for many types of wine.

Oenococcus oeni At a very low population, at the early stage of winemaking or cidermaking, it dominates after alcoholic fermentation, which is carried out by yeasts. Genomic DNA fingerprinting of Oenococcus oeni strains by pulsed-field gel electrophoresis and randomly amplified polymorphic DNA-PCR. Although some strains of Oenoccus oeni can use fructose to create mannitol, which leads to what is known as mannitol taint, a fault in the wine. However, strains present in each region belong to diverse phylogenetic groups, and the same groups can be detected in different regions, indicating that strains are not genetically adapted to regions.

Although some strains of Oenoccus oeni can use fructose to create mannitol, which leads to what is known as mannitol taint, a fault in the wine. Heterologous expression of Oenococcus oeni malolactic enzyme in Lactobacillus plantarum for improved malolactic fermentation. Taken together, the results shed light on the diversity and specificity of wild strains of O. oeni, which is crucial for understanding their real contribution to the unique properties of wines.
