Lignin Peroxidase–a Robust Tool for Biocatalysis

Lignin peroxidase (LiP) is a prospective enzyme that possesses high redox potential and multifarious biotechnological applications. The application perspective of LiP spans through different sectors such as environmental bioremediation, lignocellulose bioprocessing, biorefinery, energy, textile, and cosmeceutical industries. Despite a significant research trend toward ligninolytic enzymes, studies on LiP appears very scarce over the last several years in contrast to other identical types of extracellular ligninolytic enzymes that is, manganese peroxidase and laccase. This assertion necessitates a succinct comprehensive description of recent and state-of-the-art biocatalytic characteristics and prospective functionalities of LiP. Therefore, an effort has been put forward to cover the production, purification, and characterization aspects of microbial LiP in this chapter. In addition to detailed documentation of enzyme immobilization method and support materials, the articulated industrial applications of LiP in dye degradation and lignocellulose degradation are also briefly discussed.
