Caracterización enológica y molecular de híbridos naturales y artificiales entre las especies saccharomyces cerevisiae y saccharomyces kudriavzevii
2018
La industria enológica debe dar respuesta a las nuevas demandas del consumidor, así como responder ante los cambios en la materia prima(mosto) debidos al cambio climático, de gran repercusión en la calidad y aceptación del vino. Para ello se exigen cambios en las prácticas enológicas como el desarrollo de cultivos iniciadores de levaduras adaptadas a las nuevas condiciones de fermentación como son las bajas temperaturas para obtener vinos más aromáticos o el desarrollo de levaduras que produzcan más aromas, mayor concentración de glicerol y menos etanol. S. cerevisiae se ha descrito como la especie predominante en la fermentación alcohólica; sin embargo, otras especies del género Saccharomy…
Global analysis of the interaction between Saccharomyces cerevisiae and other Saccharomyces species of enological interest
2019
Global warming has provoked an increase in the content of sugars in grape that implies higher levels of ethanol in wines as well as unbalanced acidity, which affects the consumer perception. In addition, wine market is becoming more and more sophisticated, demanding for products with new and richer aroma profiles. Here, the solution we propose involves the use of alternative species of the Saccharomyces. Those are characterized by lower yields of ethanol than S. cerevisiae, and distinct aroma profiles potentially interesting for industry. The main problem with these yeasts is that they are easily outcompeted from the fermentative media by the action of the naturally present S. cerevisiae. T…
Subcellular distribution of calpain-1 and calpain-2 as a key event for calpain-mediated functions in physiological and neoplastic mammary models
2019
Calpains are a family of calcium-dependent proteases, which modulate their substrates rather than degrade them in such a way that modifies them. Calpains deregulations have been determined as an aggravating factor of different diseases, including cancer. Nevertheless, there are no clear records about the particular contribution of each calpain isoform in physiological processes and how these isoforms are deregulated in pathological conditions. In vivo, each calpain isoform recognizes specific proteins as substrates, and it has been suggested that calpains subcellular localization might determine their substrate recognition, and consequently their functions. In the present study we have expl…
