Lineas de Investigación
- Enzymatic reactor for micropollutants oxidation
This research line is based on the application of ligninolytic enzymes for the removal of micropollutants in wastewater. Currently we are studying the immobilization of laccase onto magnetic nanoparticles (mNPs), a support that permits an easy separation of the biocatalyst from the reaction medium by simply applying a magnetic field. I am particularly interested in the optimization of the enzymatic reaction, the mechanisms of transformation involved and the design of the different reactor configurations.
- Biomass pretreatment and production of biofuels
A biorefinery is a facility that integrates biomass conversion processes and equipment to produce fuels, power, and chemicals from biomass. I am particularly interested in the use of ligninolytic enzymes in the pretreatment of lignocellulosic biomass with the aim of producing sugars that could be used in second-generation biorefineries.
- Production of added-value products by enzymatic transformation of natural extracts
Agro-industrial residues are a potential source of bioactive phenolic compounds such as flavonoids. The use and effectiveness of flavonoids, however, sometimes are hampered by their physicochemical properties such as limited solubility and low hydrophobicity. The objective of this research line is the oxidative oligomerization of flavonoids by natural oxidative enzymes. The enzymatic transformation of these phenolic compounds leads to more bioavailable substances and with enhanced specific biological activities.
