Fermentative biotechnology: Industrial yeasts


The development of yeast strains affording better performance or to be used in new applications is a growing industrial demand. In particular, the development of commercial yeast with enhanced cold tolerance and freeze resistance has a great economic interest. Hence, a better understanding of the principles underlying the adaptation and tolerance mechanisms is a key factor for industrial strain selection. The exposure to low temperatures in S. cerevisiae activates signalling cascades that modify processes and cellular structures. Between them, the regulation of the physico-chemical properties of the plasma membrane determines in turn the activity of many proteins localized in it. However, we are far for understanding the molecular basis of such effects and of the functionality of the membrane at low temperature. In this scenario, our group makes emphasis on analysing MAPK pathways implied in the cold response, concretely the HOG and PKC and other pathways involved in lipid homeostasis.
