Some remarks on "a taxonomic key for the genus Saccharomyces" (Vaughan Martini and Martini 1993).

The practicability of Vaughan Martini and Martini's "Taxonomic Key for the Genus Saccharomyces" for the separation of S. bayanus from other Saccharomyces sensu stricto species was studied. It was concluded that the ability to grow in vitamin free medium was not a suitable character for this purpose. A new wild S. bayanus strain, isolated from exudate of Carpinus betulus was also included in this study. This appears to be the third documented strain of that species isolated outside of an artificial fermentation environment.
