Extraction and Application of Laccases from Shimeji Mushrooms (Pleurotus ostreatus) Residues in Decolourisation of Reactive Dyes and a Comparative Study Using Commercial Laccase from Aspergillus oryzae

Table 3

Colour removal of the reactive dyes DMBLR, DMBBLN, DMR, and RBBR, after 1 h and 24 h, in the presence of the commercial laccase from Aspergillus orizae in the absence (E) or presence of ABTS mediator (EM). In bold the percentage of decolourisation over 70%.
