Evaluation of brilliant blue dye biodegradation by white rot fungi and their consortia
Colored effluent from the textile industry cause adverse effects on aquatic ecosystems, leading to a deterioration of their aesthetic and a decrease in photosynthetic processes. In this study, the biodegradation of textile dye brilliant blue, BB, over flowers waste using three fungal strains Pleurotus ostreatus (Po), Pleurotus pulmonarius (Pp), Trametes versicolor (Tv) and some of their consortia was evaluated. The best conditions of degradation were determined by solid state fermentation with individual fungal species and two of its consortia C1: Po-Tv y C2: Po-Pp, through a factorial design. Likewise, the kinetics of the process was evaluated and the enzyme activity was quantified. A biodegradation percentage from BB of 99.14% was reached by Pp as single strain, under a ratio of C:N of 20:1, with four biomass plugs and of 99.19% for C2, under a ratio of C:N of 40:1, with four biomass plugs in 1:1 ratio of each selected fungus. As to the kinetics, it was found that C2 required a time of 10 days to reach 92% of BB decolourisation; this same percentage was obtained by Pp at 12 days. Regarding to the involved enzymes, it was found that the highest activity was recorded for the laccase by both individual strains and fungal consortia, with values of 6.98 ULAC/gss and 17.83 ULAC/gss respectively.
