The effect of vanillin and essential oil of mint on the growth of different strains of food spoilage yeasts in laboratory media and fruit purées was studied. Growth of Saccharomyces cerevisiae, Zygosaccharomyces rouxii, Debaryomyces hansenii and Z. bailii was inhibited in culture media and apple purée containing 2000 ppm of vanillin for 40 days storage at 27 degrees C and a(w) 0.99 or 0.95. But...

Yeasts of 17 processed fresh edible (raw) sea urchins obtained from seven countries were analyzed. In total, 45 to 7 x 10(4) colony-forming units (CFU)/g of sea urchins were recovered, and 23 yeast species were identified. Of these species, six pathogenic yeasts (Candida albicans, C. sake, Debaryomyces hansenii, Pichia anomala, Rhodotorula mucilaginosa, and Trichosporon mucoides) were detected ...

We have traced the evolution patterns of 2480 transmembrane transporters from five complete genome sequences spanning the entire Hemiascomycete phylum: Saccharomyces cerevisiae, Candida glabrata, Kluyveromyces lactis, Debaryomyces hansenii, and Yarrowia lipolytica. The use of nonambiguous functional and phylogenetic criteria derived from the TCDB classification system has allowed the identifica...

Traditional phenotypic methods and commercial kits based on carbohydrate assimilation patterns are unable to consistently distinguish among isolates of Pichia guilliermondii, Debaryomyces hansenii and Candida palmioleophila. As result, these species are often misidentified. In this work, we established a reliable method for the identification/differentiation of these species. Our assay was vali...
