In recent years, the use of enzyme in a wide range of industrial applications has grown in importance. Many of these potential enzymes may be found in nature; laccase is one of them, and it is also the oldest and most researched enzymatic system. Laccase was found by the Japanese Lacquer tree Rhus vernicifera for the first time. Laccase (p-diphenol; dioxygen oxidoreductase E.C.1.10.3.2) is a group of multi-copper enzymes that catalyse the one-electron oxidation of phenolic compounds while also reducing oxygen to water. Although the enzyme may be found in plants, insects, and bacteria, fungus, particularly basidiomycetes, are the most important sources [1,2]. The most effective microorganisms capable of widespread aerobic lignin breakdown are white-rot fungi.
