Genetic diversity of the yeast Candida utilis.
The electrophoretic karyotypes and some mtDNA restriction fragment patterns of 13 strains of Candida utilis and one strain of Hansenula jadinii were compared. PFGE separations revealed remarkable chromosome length polymorphisms between two groups of strains suggesting that perhaps they do not belong to the same species. However, all strains had the same or similar EcoRI, HindIII and BamHI mtDNA restriction patterns. The mtDNA genomes had an average size range of 55 kb. These results support the supposition that C. utilis is a yeast with a highly variable electrophoretic karyotype as already known for another imperfect yeast species, Candida albicans.
