Abstract
Analysis of the system for the utilization of lactose in some strains of yeasts belonging to the generaKluyveromyces andSaccharomyces revealed the occurrence of several genetic variants, corresponding to mutants expected on the basis of the model of Jacob and Monod for the lac system inE. coli.
These results could be useful in the taxonomic analysis and in the phylogenetic evaluation of theSaccharomycetaceae.
