Abstract
SUMMARY: A set of 142 strains of yeasts, originally described as Debaryomyces species, were examined for 64 morphological, physiological and serological characters and the results were subjected to numerical analysis. Three phenons and one individual strain emerged at the 77% similarity level. The first two phenons were each divided into three subphenons at the 85% similarity level. Assimilation of n-alkanes (C6 to C16) was most useful for the division of strains into the three phenons. The data agree with the published results of % GC content.
