PCR techniques and pulse field electrophoresis karyotyping showed wide genetic diversity in Saccharomyces cerevisiae strains isolated from spontaneous fermentations in progress at a wine cellar in the Rías Baixas appelation controlé region (Spain). The karyotyping method showed greater discriminating power than PCR profiling, making it better suited for the detection of genetic diversity in wine strains, and for the monitoring of selected strains in controlled fermentations.
