ABSTRACT=<p>Biogenic amines (BA) in wine represent a toxicological risk for the health of the consumer, with several trade implications. In this study 26 strains of <italic>Lactobacillus plantarum</italic> were analyzed for their ability to degrade BA commonly found during wine fermentation. Two strains of <italic>L. plantarum</italic> were selected in reason of their ability to degrade putrescine and tyramine. The degradation was assessed <italic>in vitro</italic>, both in presence of the BA and in presence of the specific chemical precursor and of producer bacteria. The two <italic>L. plantarum</italic> biotypes were found capable to work synergically. In addition, the survival in wine-like medium and the aptitude to degrade malic acid after alcoholic fermentation of the selected <italic>L. plantarum</italic> strains was analyzed. Our results suggest the potential application of wine <italic>L. plantarum</italic> strains to design malolactic starter cultures able to degrade BA in wine.</p>
