SUMMARY OF THE RESEARCH ACTIVITY:
We are interested in yeast biology, including both Saccharomyces and alternative genera; and paying attention to the most relevant aspects concerning biotechnological applications, in special in wine biotechnology.
During the last few years we have performed research on Saccharomyces cerevisiae adaptation to alcoholic fermentation, and the influence on yeast physiology of changes in different parameters related to climate change. We are also developing methods to reduce alcohol content of wines, based on the respiratory metabolism of non-Saccharomyces yeasts.
Our current research lines are focused on the interactions between cells for different starter cultures used for both alcoholic and malolactic fermentation (Saccharomyces and non-Saccharomcyes yeasts, as well as lactic acid bacteria). We are also exploring the impact of some yeast prion-like elements (specifically [GAR+]), on these interspecific interactions.
Our research methods include advanced functional genomics tools, metagenomics, and bioreactor technologies. In addition, we have a large experience developing genetically improved wine yeast strains. Some of them are currently used in the industry, including for example mannoprotein superproducing wine yeast strains.
