A molecular assay based on the Amplified Fragment Length Polymorphism (AFLP) technique was performed for genotyping strains of Oenococcus oeni. The AFLP technique discriminated at strain level and proved to be a valid alternative to other molecular methods. The malate metabolism was also tested in several selected strains based on AFLP analysis. According to genotyping and malate metabolism analyses some selected strains may be considered potential candidates as starters in industrial malolactic fermentation.
La tecnica molecolare AFLP è stata utilizzata per genotipizzare una popolazione di Oenococcus oeni. L'analisi AFLP ha permesso di sviluppare profili molecolari che discriminavano singoli ceppi. Su alcuni ceppi selezionati è stato studiato anche il metabolismo del malato. Dai risultati ottenuti si evince che alcuni ceppi possono essere considerati potenziali candidati da utilizzarsi come starters per fermentazioni malolattiche industriali.

Abstract
A molecular assay based on the Amplified Fragment Length Polymorphism (AFLP) technique was performed for genotyping strains of Oenococcus oeni. The AFLP technique discriminated at strain level and proved to be a valid alternative to other molecular methods. The malate metabolism was also tested in several selected strains based on AFLP analysis. According to genotyping and malate metabolism analyses some selected strains may be considered potential candidates as starters in industrial malolactic fermentation.| File | Dimensione | Formato | |
