Curriculum Vitae

Research Interests

Dr. Rizzo research activity is focused on the study of marine microbial communities associated with different matrices, both of temperate and polar environments, with particular attention paid to prokaryotic populations associated with marine invertebrates (i.e. porifera, annelids and molluscs). The first research activities involved the isolation of hydrocarbon-degrading bacteria from biotic and abiotic matrices (waters, sediment and benthic filter feeding organisms), the development of a screening pipeline to identify the biosurfactants production, the development of extraction and preliminary procedures for chemical characterization, and the realization of experimental tests to evaluate the effectiveness of these in the degradation and removal of hydrocarbons and heavy metals. Subsequently, she investigated the production of exopolysaccharides from Antarctic bacteria, and assessed their biotechnological potential, such as cryoprotective action, emulsifying activity, and chelating activity for metals. She also studied the production of antimicrobial compounds by bacteria and algae, active against pathogens of relevance for human health and aquaculture. The research activities currently carried out cover different areas of bioprospecting, and are mainly aimed at the isolation of microbial producers of bioactive molecules, with specific functions useful in industrial and non-industrial applications, such as in the medical and environmental recovery fields.
In the field of microbial ecology, she deals with deepening the functional and diversity profiling of bacterial communities in relation to different contaminants, with particular attention paid to bacteria adapted to the cold environments and their biotechnological potential.
She is currently involved in research projects on polar topics.
