TLDR
The phenol oxidases from mature fruiting bodies of Lentinus edodes (Berk.) Sing.Abstract:
The phenol oxidases from mature fruiting bodies of Lentinus edodes (Berk.) Sing., a commercially cultivated mushroom, were studied. The major phenol oxidase was a laccase with a pH optimum near 4.0 and an apparent molecular weight of 100000. Catechol oxidase and tyrosinase were also present. The laccase investigated was primarily extracellular; the highest activity was in the pigmented rind of the pileus and in the stipe. Increased laccase activity was associated with rapid growth of non-pigmented aerial mycelium and formation of pigmented primordia and fruiting bodies. Possible functions of the laccase and its regulation during the development of fruiting bodies are discussed.read more

History, overview and applications of mediated lignolytic systems, especially laccase-mediator-systems (Lignozym-process)
H.P. Call,I. Mücke +1 more
TL;DR: The general applicability of the laccase-mediator-system (Lignozym®-process) will be given by a comparison of results obtained with pulps from different sources of wood and from several pulping processes, especially regarding effects on pulps, kinetic data and specificity of the reaction.

TL;DR: It is proposed that phenol oxidase function in regulating the production of both lignin-and polysaccharide-degrading enzymes by oxidation of lign in and lignIn-related phenols when S. pulverulentum is growing on wood.

Production, Purification and Properties of Extracellular Laccase of Agaricus bisporus
TL;DR: Extracellular laccase (EC 1.18.1) of the cultivated mushroom Agaricus bisporus was produced constitutively in defined or complex media and the substrate specificity was similar to that of other fungal laccases.
