BACKGROUND Cu,Zn-superoxide-dismutase, Cu,Zn-SOD, can be obtained from different sources with different anti-inflammatory activities. In this study we compared the anti-inflammatory capacity of the marine yeast Debaryomyces hanseii Cu,Zn-SOD (Dh-SOD) with that of bovine erythrocytes (Be-SOD) in a preventive and a therapeutic fashion. METHODS Edema was induced by carrageenan injection into the...

The yeast Debaryomyces hansenii has a remarkable capacity to proliferate in salty and alkaline environments such as seawater. A screen for D. hansenii genes able to confer increased tolerance to high pH when overexpressed in Saccharomyces cerevisiae yielded a single gene, named here DhGZF3, encoding a putative negative GATA transcription factor related to S. cerevisiae Dal80 and Gzf3. Overexpre...

Most eukaryotic genes express mRNAs with alternative polyadenylation sites at their 3' ends. Here we show that polyadenylated 3' termini in three yeast species (Saccharomyces cerevisiae, Kluyveromyces lactis, and Debaryomyces hansenii) are remarkably heterogeneous. Instead of a few discrete 3' ends, the average yeast gene has an "end zone," a >200 bp window with >60 distinct poly(A) sites, the ...

PPZ1 orthologs, novel members of a phosphoprotein phosphatase family of phosphatases, are found only in fungi. They regulate diverse physiological processes in fungi e.g. ion homeostasis, cell size, cell integrity, etc. Although they are an important determinant of salt tolerance in fungi, their physiological role remained unexplored in any halotolerant species. In this context we report here m...

Abstract Seventeen samples of Calabrian ewe’s milk, cheese ( Pecorino del Poro ) made with raw goat’s and Caprino d’Aspromonte milk were used to obtain 124 yeast isolates. The most abundant species was Debaryomyces hansenii (61.3%), followed by Candida zeylanoides (32.3%) Kluyveromyces marxianus (3.2%). enzymatic profile 25 selected strains determined. Lastly, they studied for their interaction...

background and objectives : doogh is an iranian preferred dairy drink, especially in warm seasons. blowing by yeasts is a common occurring spoilage when this product is kept outside the refrigerator in warm temperature. natural additives such as herbal essential oils, which also induce the desired flavor and color, may solve this problem and retard yeast growth. spearmint, pennyroyal and some o...

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...
