Selection and characterization of autochthonous strains of Oenococcus oeni for vinification in Priorat (Catalonia, Spain)
The use of autochthonous strains of Oenococcus oeni for inducing malolactic fermentation (MLF) in wines is increasing because they are well adapted to the conditions of a specific area.
