Abstract:
:This work presents the results obtained in the treatment of industrial pulp mill wastewater (black liquor) with the white-rot fungus Trametes versicolor immobilised in nylon and polyurethane foam cubes. Reductions in colour (36%), aromatic compounds (54%) and toxicity (3.15 times reduction of the initial value) were obtained when the fungus was immobilised in nylon and good toxicity reduction (5.7-fold reduction of the initial value) when polyurethane foam was used. These results were compared with those obtained with Trametes versicolor in the form of pellets for colour and aromatic compounds (84.8% and 70.2% respectively). Correlations among different parameters have been studied. Relationships between colour and changes in the molecular weight distribution profiles, as well as a correlation between laccase production and toxicity reduction have been found. For laccase production vs. toxicity reduction a different behaviour has been observed depending on the bioreactor configuration (fixed-bed reactor with immobilised Trametes versicolor or fluidised bed reactor with pellets of Trametes versicolor).
