Dr. Gabriella Fiorentino is an Associate Professor of Biochemistry in the Department of Biology at the University of Naples Federico II in Italy. Her research primarily focuses on the molecular mechanisms of extremophiles, particularly thermophilic microorganisms, and their applications in biotechnology. She has contributed to understanding arsenic detoxification systems in organisms like Thermus thermophilus, exploring the regulation of arsenic resistance and the role of specific enzymes in this process. Dr. Fiorentino has also investigated the degradation of complex polysaccharides by thermophilic enzymes, highlighting their potential for biotechnological applications.
