“…Recent comparisons of basidiomycete genomes show that the borderline between white-rot and brown-rot fungi is not as strict as previously thought and many brown-rotters such as F. pinicola, P. placenta and G. trabeum do have laccase genes in their genomes (Riley et al, 2014). Laccase is produced by D. squalensis (Susla et al, 2007), P. rivulosus (Hakala et al, 2005), T. pubescens (Palmieri et al, 2000), F. pinicola (Gramss et al, 1999), P. placenta (Wei et al, 2010), P. pulmonarius (De Souza et al, 2004), P. radiata (Arora and Gill, 2001), P. abieticola (Koutrotsios and Zervakis, 2014), P. velutina (Boddy, 2000), A. praecox and P. ostreatus . Although the studied basidiomycetes P. pulmonarius, P. radiata, D. squalens, P. rivulosus, C. unicolor, P. abieticola, P. velutina, A. praecox, T. pubescens, P. ostreatus, F. pinicola and P. placenta produced laccase, they did not decolorize all studied dyes indicating that other enzymes than laccases were involved in decolorization of the tested dyes.…”

“…Ganoderma lucidum produced more than three laccase isozymes in liquid culture [72]. Pleurotus pulmonarius produced three laccase isozymes among which the lcc 1 and lcc 2 isoforms were produced in noninduced cultures, while lcc 3 was found only in induced-culture filtrates [73]. At least seven laccase isozymes were found in the basidiomycete CECT 20197 [74].…”

Laccases are blue multicopper oxidases, which catalyze the monoelectronic oxidation of a broad spectrum of substrates, for example, ortho- and para-diphenols, polyphenols, aminophenols, and aromatic or aliphatic amines, coupled with a full, four-electron reduction of O2 to H2O. Hence, they are capable of degrading lignin and are present abundantly in many white-rot fungi. Laccases decolorize and detoxify the industrial effluents and help in wastewater treatment. They act on both phenolic and nonphenolic lignin-related compounds as well as highly recalcitrant environmental pollutants, and they can be effectively used in paper and pulp industries, textile industries, xenobiotic degradation, and bioremediation and act as biosensors. Recently, laccase has been applied to nanobiotechnology, which is an increasing research field, and catalyzes electron transfer reactions without additional cofactors. Several techniques have been developed for the immobilization of biomolecule such as micropatterning, self-assembled monolayer, and layer-by-layer techniques, which immobilize laccase and preserve their enzymatic activity. In this review, we describe the fungal source of laccases and their application in environment protection.

“…The use of enzyme inducers has also been investigated as they not only influence the type of isoenzymes produced but also increase volumetric activity. Much attention has been paid to the chemical induction of laccases by the addition of aromatic or phenolic compounds [12,18], copper [15,23], lignin [7], and ethanol [17], among others. However, the use of a combination of inducers for increasing laccase production remains almost unexplored [13].…”

Laccases have great biotechnological potential in diverse industries as they catalyze the oxidation of a broad variety of chemical compounds. Production of laccases by basidiomycetes has been broadly studied as they secrete the enzymes, grow on cheap substrates, and they generally produce more than one isoenzyme (constitutive and/or inducible). Laccase production and isoenzyme profile can be modified through medium composition and the use of inducers. The objective of this work was to increase laccase production by Pleurotus ostreatus CP-50 through culture medium optimization and the simultaneous use of copper and lignin as inducers. Increased fungal growth was obtained through the use of a factorial fractional experimental design 2⁶⁻² where the influence of the nature and concentration of carbon and nitrogen sources was assessed. Although specific laccase production (U/mg biomass) decreased when malt extract medium was supplemented with carbon and nitrogen sources, fungal growth and laccase volumetric activity increased four and sixfold, respectively. The effect of media supplementation with copper and/or lignin on laccase production by P. ostreatus CP-50 was studied. A positive synergistic effect between copper and lignin was observed on laccase production. Overall, the use of an optimized medium and the simultaneous addition of copper and lignin improved growth, laccase volumetric activity, and process productivity by 4-, 60-, and 10-fold, respectively.
