DECOLORIZATION OF REACTIVE BLACK 5 BY IMMOBILIZED Trametes versicolor

Biological and photocatalytic treatment at pilot plant scale of synthetic coloured wastewater produced in university teaching laboratories

“…FBS contact with SWW during the first hours, and thanks to the extended aeration that kept FBS in suspension, dyes could be absorbed to cellular walls of bacteria and fungi (Blanco et al, 2018;. This is the first mechanism concerned with SBR dye removal, which is independent of the microorganism's metabolism and is strongly influenced by SSW's pH (7.0 ± 3) (Martínez-Sánchez et al, 2018). Subsequently, it was possible to initiate stain biotransformation by chromophore group modification.…”

“…Subsequently, it was possible to initiate stain biotransformation by chromophore group modification. To which, fungal extracellular ligninolytic enzymes (Laccase, MnP and LiP) and bacterial enzymes, such as peroxidases and phenol oxidases, among others participate Martínez-Sánchez et al, 2018). Dye biotransformation allows for intermediary formation that can continue with the process of partial or complete mineralization to CO 2 , fungal proliferation and bacterial biomass production.…”

“…The use of co-substrates to favour pollutant degradation with complex chemical structures has been reported in both aerobic and anaerobic processes. Martínez-Sánchez et al (2018) used Trametes versicolor immobilized in polyurethane foam for reactive black 5 dye discoloration and used Rhada mineral medium, demonstrating a discoloration greater than 84%. As a product of mineralization CO 2 was produced.…”

“…To complement the mediated action by bacteria, it is possible to incorporate to these consortiums, white rot fungi, also called ligninolytic fungi (Rivera et al, 2013;Pedroza et al, 2018;Martínez-Sánchez et al, 2018). These fungi have the capacity to remove contaminants by adsorption mechanisms to fungal cell walls and a wide range of low specificity extracellular enzymes that biotransform contaminants through demethylation, hydroxylation, oxidation and aromatic ring breakdown (Rojas et al, 2016;Blanco et al, 2018).…”

Ligninolytic Enzyme Production and Decolorization Capacity of Synthetic Dyes by Saprotrophic White Rot, Brown Rot, and Litter Decomposing Basidiomycetes

“…Much information on the decolorization of synthetic dyes by ligninolytic fungi has been obtained with Phanerochaete chrysosporium [11,37,39,56], Pleurotus ostreatus [16,49,54,57,65,68,77], Trametes versicolor [25,42,50,85], or Bjerkandera adusta [76,95,96]. Our screening showed 12 strains with the best decolorization properties.…”
