Further genetic analyses were performed using MLST (7 genes) including 10 commercial strains; the results indicated that commercial strains were grouped together, while autochthonous strains distributed among different genetic clusters. Acad. Cycles of Negroamaro must fermentations inoculated with Oenococcus oeni strain Lalvin VP41™ and Saccharomyces cerevisiae strain Lalvin ICV-D254 ® co-immobilized in alginate beads (sample C1). -, Bon E., Delaherche A., Bilhère E., De Daruvar A., Lonvaud-Funel A., Le Marrec C.

Clipboard, Search History, and several other advanced features are temporarily unavailable. Oenococcus oeni was observed in 80% of the samples collected. Mashed it for an hour at 155b0F, sparged to get 7 gallons of wort, then boiled for an hour. Oenococcus oeni, mainly isolated in fermenting grape and apple juices, is essential in wine and cider production but spoils canned mango juice.At a very low population, at the early stage of winemaking or cidermaking, it dominates after alcoholic fermentation, which is carried out by yeasts. doi: 10.1111/j.1750-3841.2012.02895.x.
