Research interests

The marine microalgae are characterized by a high biodiversity and they have a strong biotechnological potential that has been poorly explored. Together with the macroalgae, marine microalgae are very important for the reduction of the greenhouse effect. They produce several natural biochemical compounds that have a strong interest for the exploitation at the industrial level too. At the moment only few species have been used for commercial applications as Spirulina, Chlorella, Dunaliella, but it is still complicated to produce high amounts of microalgae biomass. During these years I worked in the creation of a marine microalgae culture collection (several are local species but other are their cosmopolitan counterparts) belonging to Bacillariophyceae, Dinophyceae, Chlorophyceaee and Prymnesiophyceae family. I am working in expanding the collection through the isolation of new species from the Gulf of Naples, focusing my attention in their purification and characterization. I selected from this collection peculiar strains resistant to contaminants, suitable for cultivation and for biotechnological applications as well. Furthermore microalgae strains are also required by other research groups in the Institute as well as for  basic research application and I use them as starters in larger volumes. My personal interest is also aimed in the optimization of  massive culture of marine microalgae in closed, semi-continuous and/or discontinuous systems, both using fermenters and photobioreactors. I improved my knowledge in the procedures used to increase the production of natural bioactive molecules, through the variation of biological and physico-chemical parameters. Moreover, I am part of the research projects focused on biotechnological pharmaceutical applications of marine microorganisms, to produce anti-cancer, antigens and adjuvants for vaccines, anti-inflammatory, antibacterial and antioxidant compounds. I am improving my knowledge on the use of marine microalgae for biotechnological applications such as cosmetics and nutraceutics.
