Screening of freshwater fungi for decolorizing multiple synthetic dyes

Abstract

The biodegradation of synthetic dyes by fungi is emerging as an effective and promising approach. In the present study, freshwater fungal strains isolated from submerged woods were screened for the decolorization of 7 synthetic dyes. Subsequently, 13 isolates with high decolorization capability were assessed in a liquid system; they belonged to 9 different fungal species. Several strains exhibited a highly effective decolorization of multiple types of dyes. New absorbance peaks appeared after the treatment with 3 fungal strains, which suggests that a biotransformation process occurred through fungal biodegradation. These results showed the unexploited and valuable capability of freshwater fungi for the treatment of dye-containing effluents. The ability of certain fungi to decolorize dyes is reported here for the first time.

Textiles

“…The study was found that color removal and chemical oxygen demand (COD) reduction efficiencies were 88% and 53% for photocatalytic degradation, respectively. Yang et al, (2016) screened freshwater fungal strains isolated from submerged woods for the decolorization of 7 synthetic dyes. Subsequently, 13…”

Optimization of Culture Condition for Enhanced Decolorization of Direct blue Dye by Aspergillus flavus and Penicillium canescens

“…Phanerochaete chrysosporium was found to be able to decolorize and mineralize direct blue "80" dye up to 99.6% and textile waste effluent up to 97.7 % (Shinkafi et al 2015). Yang et al (2016) also showed the valuable capability of freshwater fungi for the treatment of dye-containing effluents. Dye decolorization with microorganism is low cost effective and environmentally friend and the only way for ultimate controlling of pollution generated by textile and dye stuff industries (Ponraj et al, 2011).…”

Reactive Black 5 Degradation on Manganese Oxides Supported on Sodium Hydroxide Modified Graphene Oxide

“…Many research papers have focused on the removal methods of azo dyes in order to decrease their effect on environment and human health. These techniques could be classified in biological (biodegradation, biosorption, bioaccumulation, applying bacteria, or algae) [15][16][17][18], chemical (ozonation, advanced oxidation processes (AOPs), electrochemical degradation, photocatalysis) [19][20][21][22] and physical methods (adsorption, ion exchange) [23][24][25], depending on the type of process. Adsorption is considered to be quite attractive in terms of effectiveness and ultimate removal, while catalytic oxidation in terms of cost and of a high degree of dye elimination [26][27][28].…”
