Recombinant Expression of Archaeal Superoxide Dismutases in Plant Cell Cultures: A Sustainable Solution with Potential Application in the Food Industry.

ABSTRACT: Superoxide dismutase (SOD) is a fundamental antioxidant enzyme that neutralises superoxide ions, one of the main reactive oxygen species (ROS). Extremophile organisms possess enzymes that offer high stability and catalytic performances under a wide range of conditions, thus representing an exceptional source of biocatalysts useful for industrial processes. In this study, SODs from the thermo-halophilic Aeropyrum pernix (SOD_Ap) and the thermo-acidophilic Saccharolobus solfataricus (SOD_Ss) were heterologously expressed in transgenic tomato cell cultures. Cell extracts enriched with SOD_Ap and SOD_Ss showed a remarkable resistance to salt and low pHs, respectively, together with optimal activity at high temper
