Abstract
Laccase, a type of multicopper oxidase, exhibits several notable advantages, including broad distribution, wide catalytic scope, and high oxidation-reduction potential. Owing to its enormous potential in food, textiles, paper, chemical synthesis, and bioremediation, laccase is considered a green catalyst in wide-ranging industrial applications. To aid in understanding the current developments in laccase research, this review introduces the physiological functions, classification, and reaction mechanisms of laccase, with a focus on improvement strategies. In addition, the updated studies and advancements in laccase production are summarized. Finally, the possible research trends and general development directions for more efficient laccase production are also proposed.
