Characterization of Indigenous Microbial Communities in Vineyards Employing Different Agronomic Practices: The Importance of Trunk Bark as a Source of Microbial Biodiversity

Microbiomes are essential to viticulture and winemaking since various fungi bacteria can exert positive negative effects on grape health wine quality. The current work evaluates the communities of culturable associated with Corvina vines derived from two vineyards a similar terroir (within Valpolicella DOC area, Italy) but which different management practices were employed: organic conventional farming. Samples bark grapes collected in four spatial points for each vineyard. Populations bark-associated microorganisms monitored during ripening season (at veraison at harvest time), results integrated data grape-associated microorganisms, sampled right before harvest. Culturable populations determined by plate counting WL PCA culture media. For fungi, biodiversity was also assayed all samples through molecular methods, ITS-RFLP analysis. Although this does not represent comprehensive evaluation microbiome, countable only portion microbial biodiversity, our emphasize importance vine trunk bark, as an interesting habitat be characterized monitoring potential source viable species further isolation.
