La conservación del acervo documental

No cabe duda que uno de los grandes problemas de nuestro tiempo es la salvaguarda de los testimonios históricos de las culturas y civilizaciones pasadas y presentes. Esta preocupación se expresa a través de numerosas manifestaciones de interés público centradas en el patrimonio cultural, que van desde reivindicaciones populares hasta amplias campañas de restauración de bienes culturales promovidas por el Estado o patrocinadas por empresas privadas.Tópico 1: Aspectos teóricos, históricos, legales, económicos y tecnológicos de la restauración y conservación de bienes patrimoniales

Metabolic flux response to salt induced stress in the halotolerant yeast Debaryomyces hansenii

The toxic effect of NaCl and KCl, on growth of the marine yeast Debaryomyces hansenii on glucose or glycerol was studied. Above threshold value both salts inhibited specific growth rate, specific glucose and glycerol respiration rates and specific glucose fermentation rate, as well as biomass yields. The exponential inhibition constant, k, and minimum toxic concentration, cmin, were similar for all physiological parameters assayed. The effect of either salt in the specific activity of several glycolytic enzymes showed a similar inhibition pattern, although at much lower salt concentrations. In agreement with published results on glycerol phosphate dehydrogenase stimulation by salt, we present evidence in which a general glycolytic flux deviation could occur naturally during salt stress, due to the intrinsic sensitivity of the glycolytic enzymes responsible for the prosecution of glycolysis to intracellular ion concentrations.EC Contract CT 93-830 from AIR Program

Yeast orthologues associated with glycerol transport and metabolism

Orthologous yeast genes associated with glycerol transport and metabolism

Apresentação efectuada nas "11as Jornadas de Biologia de Leveduras Professor Nicolau van Uden", realizadas na Escola Superior Agrária de Bragança, em Maio de 2003.Glycerol, besides acting as compatible solute, accumulated by S. cerevisiae to counteract the low aw stress environments, is a key compound in the regulation of multiple metabolic pathways. Most of the genes involved in glycerol consumption and production are now available for this yeast. Furthermore, three genes had been described as involved in glycerol uptake as well as export, respectively, GUP1/21 and FPS123. Altogether, these genes regulate intracellular glycerol levels in a way not yet completely unveiled. Some of these mechanisms, like the stimulation of glycerol production and accumulation under stress growth conditions and the presence of constituvely active transport for glycerol, are common to a series of other yeasts4. Being so, we decided to search for some of the genes from glycerol uptake and metabolism in some of those yeasts. We began using the partial genome sequencing available for several yeasts from the Génolevures Program. Further ahead we included Candida albicans from Stanford Genome Sequencing Data Base. Our search focused on GUP1/2, FPS1, GPD1/2 (glycerol 3-P dehydrogenase) and GUT1 (glycerol kinase) genes. From this search we choosed the sequences with higher similarity, which were present in Candida tropicalis, Kluveryomyces marxianus, Kluveryomyces lactis, Kluveryomyces thermotolerans, Pichia angusta, Pichia sorbitophila and Zigossacharomyces rouxii, besides Candida albicans. The entire sequences of the genes were obtained using standard procedures, like primer walking sequencing and RACE (rapid amplification of cDNA ends). Genes were obtained by PCR and complementation analysis was done. Sequences were used to create/enlarge gene families, to explore the evolutionary relationship of these species and to establish the putative relation between sequence and function

Le cep prend ses racines profondément dans le sol. Le tronc du cep est robuste et mène la sève au feuillage pour nourrir le fruit et le pousser à maturité. Le grain de l’écorce protège le tronc. Les raisins séchés au soleil servent aussi à faire le vin – la technique du passerillage. Les cépages construisent la galaxie du vin.
