In this study, a TRFLP approach was developed for the identification and discrimination of yeasts and used to construct a TRFLP database comprising 121 strains of yeast (representing 24 genera and 72 species) associated with wine and food fermentations. This database exhibits sensitive discrimination among species and robust intra-specific conservation of TRFLP profiles, enabling reliable characterization of mixed yeast communities. The yeast ecology of a sweet, botrytized wine fermentation from two separate vintages was analyzed using this database, demonstrating the utility of this method for fast-paced, qualitative detection and identification of differences in yeast community structures over time in a complex, diverse fermentation system.
