Recent advancement in the biotechnological application of lignin peroxidase and its future prospects

The ligninolytic enzymes (laccase, manganese peroxidase, lignin peroxidase) have a wide range of applications, including in the industrial and environmental sectors. Lignin peroxidase (LiP; EC 1.11.1.14) is a heme-containing key enzyme of lignin degradation, and it is known as diaryl propane oxygenase. Being an oxidoreductase in chemical nature, LiP is an H₂O₂-dependent enzyme and catalyzes various phenolic and nonphenolic compounds. The diverse variety of microbes are known for LiP production in the environment. However, fungal-mediated ligninolytic enzymes have been studied extensively with its even greater advantages due to their thermostability, a wide range of pH values, fewer by-products, and high specificity. In the presenting chapter, we explore the ligninolytic enzymes, specially dedicated to lignin peroxidase. The broad and detailed information has dedicated to lignin peroxidases, like; the sources, production, mode of action, and various applications in industrial sectors. The potential use of this enzyme extends through many industries, including; pulp and paper, cosmetics, textile, bioremediation, energy, and cosmetics. Besides, this chapter also provides recent updates on lignin peroxidase production along with their current applications.
