Physical removal of textile dyes from effluents and solid-state fermentation of dye-adsorbed agricultural residues

摘要: Abstract Three agricultural residues, wheat straw, wood chips and corn-cob shreds were tested for their ability to adsorb individual dyes dye mixtures in solutions. Up 70–75% colour removal was achieved from 500 ppm solutions at room temperature using straw. Increasing the had little effect on adsorption capacity of residues. The resulting dye-adsorbed residues found be suitable substrates solid-state fermentation (SSF) by two white-rot fungi; Phanerochaete chrysosporium Coriolus versicolor. Both strains grew uninhibited produced a maximum protein content 16, 25 35 g 19, 23 50 SSF 100 dry weight chips, respectively, supplemented with ammonical nitrogen give C:N ratio 20:1. This approach provides preliminary results remediation textile effluent conversion into soil conditioner.
