Enhancement of laccase production and malachite green decolorization by co-culturing Ganoderma lucidum and Trametes versicolor in solid-state fermentation
Optimization of laccase production in white-rot fungi has been extensively studied. Metallic and aromatic compounds have been found to enhance enzyme production, but the development of bioremediation as an application field of this enzyme requires clean technologies. In this work, co-cultivation of...

Optimization of laccase production in white-rot fungi has been extensively studied. Metallic and aromatic compounds have been found to enhance enzyme production, but the development of bioremediation as an application field of this enzyme requires clean technologies. In this work, co-cultivation of Ganoderma lucidum and Trametes versicolor was performed, showing remarkable enhancement of laccase activity. Dual cultures were assayed for malachite green degradation (MG) in solid state fermentation (SSF) using a sawdust-based medium. The time for achieving complete decolorization of MG in co-cultivation was markedly shorter than that observed in monocultures. Dual-species treatment did not differ in wood dry weight loss and lignin, cellulose and hemicellulose degradation, compared to monocultures; but the selectivity index (lignin loss/cellulose loss) of dual cultures was markedly higher than those attained by monocultures.
