Research interests

Among the actual challenges of the blue biotechnology, there is the need of increasing the efficiency of biomass production and bioactive molecules synthesis from microalgae. Among the valuable products produced by these organisms, carotenoids have many applicative purposes, such as food additives, thanks to their antioxidant activities.
The overall objective of my project is the enhancement of carotenoid biosynthesis by diatoms in culture, maintaining as high as possible the photosynthetic and growth rates. The aim of my studies is to investigate the effect of light manipulation, inducing photosynthetic acclimation/regulation by microalgae for enhancing carotenoid production. To achieve these goals different approaches are used, such as ecophysiological, molecular, biochemical and metatranscriptomic studies.
