Abstract
The yeast Debaryomyces hansenii is considered a marine organism. Sea water contains 0.6 M Na(+) and 10 mM K(+); these cations permeate into the cytoplasm of D. hansenii where proteins and organelles have to adapt to high salt concentrations. The effect of high concentrations of monovalent and divalent cations on isolated mitochondria from D. hansenii was explored. As in S. cerevisiae, these mitochondria underwent a phosphate-sensitive permeability transition (PT) which was inhibited by Ca(2+) or Mg(2+). However, D. hansenii mitochondria require higher phosphate concentrations to inhibit PT. In regard to K(+) and Na(+), and at variance with mitochondria from all other sources known, these monovalent cations promoted closure of the putative mitochondrial unspecific channel. This was evidenced by the K(+)/Na(+)-promoted increase in: respiratory control, transmembrane potential and synthesis of ATP. PT was equally sensitive to either Na(+) or K(+). In the presence of propyl-gallate PT was still observed while in the presence of cyanide the alternative pathway was not active enough to generate a Delta Psi due to a low AOX activity. In D. hansenii mitochondria K(+) and Na(+) optimize oxidative phosphorylation, providing an explanation for the higher growth efficiency in saline environments exhibited by this yeast.

Abstract
The efficiency of mitochondrial DNA (mtDNA) restriction analysis and random amplification of polymorphic DNA (RAPD)-PCR to characterize yeasts growing on dry-cured Iberian ham was evaluated. Besides, the distribution of the main species and biotypes of yeasts in the different ripening areas of this product was investigated. MtDNA restriction analysis allowed yeast characterization at species and strain level. RAPD-PCR with the primers (GACA)(4) and (GAC)(5) was inappropriate for characterization at species level. Most of the mtDNA restriction patterns detected in dry-cured Iberian ham were consistent with Debaryomyces hansenii. Several yeasts biotypes were associated to specific geographic areas of dry-cured Iberian ham ripening.

Abstract
Only a handful of cases of human Candida lambica infections have been published up to now. We report a Candida lambica fungemia in a young intravenous drug abuser. Using a popular chromogenic agar and a commercial phenotyping gallery, the fungus was initially misidentified as Candida krusei. Key tests to distinguish these closely related species are maximum growth temperature and assimilation of certain substrates present in more elaborate phenotyping assays. Definite confirmation is possible using molecular techniques. Susceptibility testing of the isolate demonstrated amphotericin B (MIC 0.125 microg/ml) susceptible, flucytosine (MIC 2 microg/ml) susceptible, itraconazole (MIC 0.064 microg/ml) susceptible, voriconazole (MIC 1 microg/ml) susceptible, and fluconazole (MIC >64 microg/ml, resistant).

Abstract
Em 10 fazendas da região da Serra do Salitre, MG, foram coletadas amostras de leite, soro fermentado (pingo), coalhada e queijo frescal para avaliar a microbiota de bactérias láticas e leveduras presentes. Uma diversidade menor de bactérias láticas foi observada durante a produção do queijo quando comparada à de leveduras. As espécies de bactérias láticas mais freqüentes foram Lactococcus lactis, Enterococcus spp., Enterococcus faecalis e Streptococcus agalactiae e de leveduras foram Debaryomyces hansenii e Kluyveromyces lactis. Apenas as populações de Enterococcus spp., Enterococcus faecalis e Leuconostoc mesenteroides apresentaram aumento significativo durante a produção do queijo. As espécies de bactérias láticas e leveduras encontradas nos diferentes substratos estudados podem ser responsáveis pelas características de aroma e sabor do queijo artesanal da Serra do Salitre.

Abstract
Fifteen wild yeast strains were isolated in two factories of a lager brewing company in Poland. Their identification with API 32C system showed mainly the presence of Candida sake species (7/15). To differentiate the isolates, randomly amplified polymorphic DNA (RAPD) with (GTG)(5), (GAC)(5), (GACA)(4) microsatellite primers and M13 core sequence (5'-GAG GGT GGC GGT TCT-3') were chosen. The results of patterns similarity are presented as dendrograms for each RAPD analysis and for overall patterns. On the overall patterns, all isolates identified as C. sake, except Strain No. 1, were regrouped in one cluster. Collection strain C. sake CBS 617 was similar in 46% to the cluster with six isolates (Strain Nos. 3, 6, 8, 11, 13, 14). The second reference strain C. sake CBS 159 and the Strain No. 1 were regrouped with other Candida species (collection strains) showing, respectively, only 20% and 42% of similarity to other C. sake strains. The similarity based on the overall dendrogram between isolate Nos. 3, 6, 8, 11, 13, 14 and C. sake CBS 617 was 49%. Between those strains and other Candida, the similarity was only 37%.

Abstract
DNA microarrays of 86 genes from the yeasts Debaryomyces hansenii, Kluyveromyces marxianus, and Yarrowia lipolytica were developed to determine which genes were expressed in a medium mimicking a cheese-ripening environment. These genes were selected for potential involvement in lactose/lactate catabolism and the biosynthesis of sulfur-flavored compounds. Hybridization conditions to follow specifically the expression of homologous genes belonging to different species were set up. The microarray was first validated on pure cultures of each yeast; no interspecies cross-hybridization was observed. Expression patterns of targeted genes were studied in pure cultures of each yeast, as well as in coculture, and compared to biochemical data. As expected, a high expression of the LAC genes of K. marxianus was observed. This is a yeast that efficiently degrades lactose. Several lactate dehydrogenase-encoding genes were also expressed essentially in D. hansenii and K. marxianus, which are two efficient deacidifying yeasts in cheese ripening. A set of genes possibly involved in l-methionine catabolism was also used on the array. Y. lipolytica, which efficiently assimilates l-methionine, also exhibited a high expression of the Saccharomyces cerevisiae orthologs BAT2 and ARO8, which are involved in the l-methionine degradation pathway. Our data provide the first evidence that the use of a multispecies microarray could be a powerful tool to investigate targeted metabolism and possible metabolic interactions between species within microbial cocultures.

Abstract
Debaryomyces hansenii is a salt-tolerant yeast that contains high amounts of internal Na(+). Debaryomyces hansenii kept more sodium than Saccharomyces cerevisiae in both the cytoplasm and vacuole when grown under a variety of NaCl concentrations. These results indicate a higher tolerance of Debaryomyces to high internal Na(+), and, in addition, suggest the existence of a transporter driving Na(+) into the vacuole. Moreover, a gene encoding a Na(+) (K(+))/H(+) antiporter from D. hansenii was cloned and sequenced. The gene, designated DhNHX1, exhibited significant homology with genes of the NHE/NHX family. DhNHX1 expression was induced neither at low pH nor by extracellular NaCl. A mutant of S. cerevisiae lacking its own Na(+) transporters (ena1-4Delta nha1 Delta nhx1 Delta), when transformed with DhNHX1, partially recovered cation tolerance as well as the ability to accumulate Na(+) and K(+) into the vacuole. Our analysis provides evidence that DhNhx1p transports Na(+) (and K(+)) into the vacuole and that it can play an important role in ion homeostasis and salt tolerance.

Abstract
The aims of this work were to identify and characterize for some important technological properties the yeast species present throughout the ripening process of Pecorino Crotonese, a traditional cheese produced in a well defined area of Southern Italy. In particular, the strain technological properties considered include fermentation/assimilation of galactose and lactose, assimilation of lactate and citrate in the presence of different NaCl concentrations, hydrolysis of butter fat, skim milk, gelatine and casein, production of brown pigments in cheese agar and ability to produce biogenic amines. High yeast levels were recorded in cheese samples already after 5 h of brining (about 5 log cfu/g) and these concentration remained constant during ripening. The yeast isolates belonged to restrict number of yeast species. While Kluyveromyces lactis and Saccharomyces cerevisiae were isolated prevalently in the first stages of Pecorino Crotonese production, Yarrowia lipolytica and Debaryomyces hansenii dominated during the later stages of maturation. Otherwise, the latter two were very NaCl resistant species. In fact, D. hansenii strains conserved the ability to assimilate lactose and galactose in the presence of 10% NaCl, while almost all the strains of Y. lipolytica isolated assimilated citrate and lactate up to 7.5% NaCl. Y. lipolytica isolates evidenced also the highest proteolytic and lipolytic activities and the capability to catabolize tyrosine producing brown pigment. In addition they resulted in the highest aminobiogenic potential decarboxylating ornithine, phenylalanine, tyrosine and lysine. However, they were not able to produce histamine, biogenic amine produced by three strains of D. hansenii.
