title: Genomic DNA fingerprinting of Oenococcus oeni strains by pulsed-field gel electrophoresis and randomly amplified polymorphic DNA-PCR.
abstract: Genetic diversity of 60 Oenococcus oeni strains from different wines was evaluated by numerical analysis of (i) pulsed-field gel electrophoresis (PFGE) patterns with endonuclease ApaI and (ii) randomly amplified polymorphic DNA (RAPD)-PCR fingerprints with four oligonucleotide primers. Sixty-two percent of the strains could be distinguished by PFGE, whereas most strains were identified by distinct RAPD-PCR profiles and associated according to the geographical origin. Because of its rapidity and reliability, RAPD-PCR appeared to be a suitable method for typing and monitoring O. oeni strains in winemaking.
