Purification and characterization of the extracellular laccase produced by Trametes polyzona WR710-1 under solid-state fermentation
Laccase from Trametes polyzona WR710-1 was produced under solid-state fermentation using the peel from the Tangerine orange (Citrus reticulata Blanco) as substrate, and purified to homogeneity. This laccase was found to be a monomeric protein with a molecular mass of about 71kDa estimated by SDS-PAG...
