Resumen

Genetic typification of 120 bacterial isolates of Lactobacillus plantarum and Oenococcus oeni from different Rioja musts and wines was performed by numerical analysis of pulsed-field gel electrophoresis (PFGE) patterns with endonuclease SfiI, and 46 of them were also studied by randomly amplified polymorphic DNA (RAPD)-PCR. A comparative study of both typification methods applied to L. plantarum and O. oeni oenological strains was performed. Bacterial species was determined both by biochemical identification methods and by specific PCR analysis. A wide variety of restriction digest patterns were detected by PFGE among L. plantarum strains (36 unrelated patterns and one closely related pattern, out of 48 isolates), as well as among O. oeni strains (18 unrelated patterns out of 72 isolates). PFGE was shown to be a suitable method for strain differentiation and to determine which strains are present in wine fermentations, with a discriminatory power to type L. plantarum and O. oeni strains higher than that of RAPD-PCR. © 2007 Springer-Verlag.
