Characterization of oenological strains of Saccharomyces cerevisiae using cellular fatty acid and mtDNA restriction polymorphism analysis

Abstract

Cellular fatty acid analysis and mitochondrial DNA restriction analysis are compared for categorizing isolates of Saccharomyces cerevisiae. The two methods gave similar results when seven isolates were studied, with three groups being differentiated. However, the results obtained with the mitochondrial DNA restriction analysis were clearer and easier to interpret than the results obtained with the cellular fatty acid analysis. Moreover, this latter technique was not adequate when a high number of samples were studied.
