Fungal Psychrophilic Enzymes: Determination Techniques, Properties, Applications

Abstract

Extensive portions of the Earth's surface, exceeding 70%, are characterized by extremely low temperatures, which sustain a substantial diversity of microbial life. Temperature represents a critical environmental factor governing the global distribution of microorganisms. Psychrophilic microorganisms constitute the predominant biological entities within these frigid ecosystems, exhibiting cold-active enzymes with considerable potential for applications in both scientific inquiry and commercial endeavors. These psychrophiles have evolved adaptive mechanisms to facilitate sustenance, reproduction, and the maintenance of active metabolic processes under conditions of low thermal energy. Enzymes isolated and purified from psychrophilic organisms demonstrate efficient catalytic activity at reduced temperatures, positioning cold-active enzymes as a valuable resource for biotechnological applications. The capacity for catalysis at low temperatures necessitates specific structural dynamics within the active site region; however, the interplay between protein conformational stability and enzymatic function is nuanced. Therefore, a comprehensive examination of the effectiveness and applicability of various psychrophilic enzymes within industries encompassing food processing, pharmaceuticals, brewing, bioremediation, and molecular biology.
