CV

Basic and biotechnological studies of algae are conducted with the following objectives:
  1. Evaluation of metabolite production with potential applications in biofuel, biofertilizer, food, pharmaceutics and material industries.
  2. Analysis of different microalgal biorefinery models.
  3. Assessment of bioremediation processes for microalgal biomass production.


Lines of Research

  • Microalgae cultures in photobioreactors and raceway ponds.
  • Microalgae oil production for biodiesel.
  • Microalgae cultures for essential fatty acid production.
  • Metabolic pathways involved in lipid synthesis in microalgae.
  • Value-added products from microalgae under a biorefinery approach.
  • Microalgal biomass production using wastewater.
  • Spore-cultures from native macroalgae.
  • Value-added production from red algae.
