The aim of this interdisciplinary approach is to provide innovative solutions to
environmental problems, in particular, improving the treatment of textile industrial effluents and finding a
use for the residual biomass generated from palm tree (Bactris gasipaes) extraction. Three types of white-rot
fungi were cultivated applying different strategies for the decolorization the textile effluents: i) solid-state
fermentation (SSF), ii) submerged fermentation (SF), and iii) adsorption. In all cases, it was used the
peach-palm residue. In the SSF strategy, the decolorization process and laccase production were enhanced
by increasing the concentration of final effluent. Even though the highest decolorization percentage (80%)
was attained after 10 days of fermentation with G. lucidum EF 31 applied in the treatment of a final effluent,
no significant differences were found in relation to the other two fungi. The decolorization efficiency
obtained in the SF was lower compared with SSF, however, the presence of final effluent in the SF process
improved the laccase activity. It was noted that the addition of peach-palm residue in this system provides a
habitat for the fungus as well as a suitable source material for laccase production with the consequent
decolorization of the effluent.
