Clinical Microbiology.

    • >The increase of antibiotic resistance of pathogenic bacteria has currently become a leading public health problem worldwide. Infections caused by carbapenemase-producing enterobacteriaceae (CPE) have largely increased in the last few years, and in addition, are associated to high mortality rates. The overall objective of this work is to expand our knowledge in the molecular mechanisms that enable the acquisition and dissemination of antibiotic resistance genes in pathogenic bacteria. Moreover, we are interested in determining which other physiological and ecological characteristics are involved in their survival. The aim is to improve diagnosis and treatment, as well as attenuate the processes of resistance dissemination.


      • >Monoclonal antibodies are used as drugs for the treatment of different types of cancer. Bifunctional or bispecific antibodies are molecules with two different recognition domains, which allow them to bind two different epitopes. The bispecific LiTe antibody has two different domains: (i) scFv antiCD3 recognising CD3+ T-lymphocytes; and (ii) VHH (Camelid heavy-chain antibody) anti-EGFR that allows binding to tumour cells expressing surface endothelial growth factor receptor (EGFR+) (Molgaard et al., 2018). We are trying to optimise conditions needed to express the LiTe antibody in E. coli and its later purification to be used in anticancer therapy.

Food Microbiology.

    • >The aromatic complexity and the quality of wines is highly influenced by the yeast species involved in the fermentation process. The objective of this project is selecting strains from different geographic locations to study their fermentative characteristics and biotechnological potential. To do so, we carry out fermentations with different yeast combinations, study their population dynamics throughout the fermentation process, and analyse quantitative and qualitatively a set of compounds (alcohols, acetates, esters) directly involved in the aromatic complexity of wine. These analyses allow the selection of the best strains to be used as starter cultures to produce wines with the desired quality and organoleptic characteristics.Polyphenols are important antioxidant compounds naturally found in plant foods. Grape polyphenols are well known, but the amount of these compounds in grape must has not been well characterised until now. The concentrated grape must is a product of great demand in the food industry, for infant feeding. Our research is focused to determine if the process of juice concentration affects the polyphenolic content of the final product and to what extent.
