Since my doctoral studies, my research interest has focused on bacterial metabolism and enzymology. Initially, I worked on the amino acid metabolism of a glutamic acid overproducing bacterium. In the1990s, my studies concentrated on the production, purification and the stabilization of penicillin G acylase from a mutant of E. coli. Over the last nine years, after collobarating with Prof. Rick Cavicchioli, I have started to work on the carbon and nitrogen metabolisms of oligotrophic and cold adapted prokaryotes such as S. alaskensis and M. burtonii, respectively. Since 2010, my project interest has progressed onto the kinetic and thermodynamic characterization of the functional properties of a hybrid versatile peroxidase from B. adjusta. Recently, I have focused on the proteases from cold adapted bacterial strains.
