Web2.3.5 Laccase. Laccase is a copper-containing oxidase enzyme present in many microorganisms, plants, and fungi that plays an important role in the biodegradation of lignin and is known as a lignin-modifying enzyme. The enzyme Laccase is used in the hydrolysis of agricultural residues of lignocellulosic compounds (Chen et al., 2024 ). WebSep 3, 2024 · Laccase from Trametes sp. was encapsulated on sol–gel support showed a drift in operating pH with the enzymatic activity as a linear function of the amount of immobilized enzyme (Mohidem and Mat 2009). A spongin-based biopolymeric scaffold was used to study the laccase-mediated degradation of three bisphenolic compounds.
