“…In a previous report it was demonstrated that supernatants from Fomes sclerodermeus with laccase activity were able to degrade malachite green dye (Papinutti et al, 2006). Decolorization studies with Trichoderma virens showed high decolorization ability (99.6%) for brilliant blue dye (Sweety et al, 2017). The current study also showed the ability of the reduction of both dyes by the bacterial isolates.…”

Textile waste pollutants are the most polluting waste water and their treatment is greatly challenging for their safe discard. Microbial communities have potential ability to decolorize synthetic commercial dyes used for textile dyeing. Therefore, this study was aimed to develop potential dye degrading microbial biofilms from endophytic fungi and soil bacteria. Endophytic fungi were isolated from the leaves of Eleusine indica (Linn) and bacteria were isolated from soil samples obtained near textile effluent dumping site in Biyagama Industrial zone, Sri Lanka. Biofilms were developed after screening the fungal and bacterial isolates with Malachite green and Nigrosin disodium dyes separately and the decolorization assay was performed for biofilms along with monocultures to evaluate their ability for dye decolorization. The highest significant (P< 0.05) decolorization percentages were observed by Tricoderma harzianum (F2) and Bacillus subtilis (B1) for both dyes. All the biofilm combinations showed higher decolorization percentage than that of the monocultures. Thus, it can be concluded that the biofilms can be used as an efficient biological tool for textile effluent treatment.

“…When testing the ability of Aspergillus niger and Phlebiopsis cf. ravanelli of decolorize synthetic dyes, Sweety et al [ 50 ] found that while increasing concentrations of carbon sources (glucose or lactose) in the culture medium favored the biodegradation, nitrogen (supplied as ammonium sulphate or ammonium nitrate), when abundant (>0.5%), inhibited the decolorization of crystal violet and orange G-II. The role on nitrogen availability determining the metabolic pathways needs further exploration, what has been achieved recently through genomic and proteomic approaches [ 51 ].…”

The main organochlorinated compounds used on agricultural crops are often recalcitrant, affecting nontarget organisms and contaminating rivers or groundwater. Diuron (N-(3,4-dichlorophenyl)-N ′ ,N ′ -dimethylurea) is a chlorinated herbicide widely used in sugarcane plantations. Here, we evaluated the ability of 13 basidiomycete strains of growing in a contaminated culture medium and degrading the xenobiotic. Dissipation rates in culture medium with initial 25 mg/L of diuron ranged from 7.3 to 96.8%, being Pluteus cubensis SXS 320 the most efficient strain, leaving no detectable residues after diuron metabolism. Pycnoporus sanguineus MCA 16 removed 56% of diuron after 40 days of cultivation, producing three metabolites more polar than parental herbicide, two of them identified as being DCPU and DCPMU. Despite of the strong inductive effect of diuron upon laccase synthesis and secretion, the application of crude enzymatic extracts of P. sanguineus did not catalyzed the breakdown of the herbicide in vitro, indicating that diuron biodegradation was not related to this oxidative enzyme.

“…The maximum decolorization (89.2%) of synthetic textile dye wastewater by Phanerochaete chrysosporium was obtained when rice bran was used as an additional carbon source to supplement other carbon sources (Kiran et al, 2019 ). A study conducted by Sweety et al ( 2017 ) showed that the optimized amounts of nitrogen sources for the fungal ( Trichoderma virens, Phlebiopsis cf. ravenelii , Talaromyces stipitatus and A. niger ) degradation of azo dyeswere 0.5% and 0.2% of ammonium sulfate and sodium nitrate, respectively.…”

“…The authors also found that the optimized amounts of carbon sources for the degradation of azo dyes were1% and 0.5% of glucose and lactose, respectively. The addition of a nitrogen source at the concentration above 0.5% decreased the percentage of decolorization, whereas the decolorization rate increased with further increase in concentration of the carbon source to upto 0.5% (Sweety et al, 2017 ). However, a study by Akdogan et al ( 2014 ) showed that higher concentrations of carbon sources (glucose, maltose and fructose) did not contribute to higher decolorization of Reactive Blue 19, and the yield of decolorization was very low with some carbon sources (glycerol and starch).…”

Currently, globalization, urbanization and industrialization have led to several environmental issues. In many industries, particularly in textile industries, the extensive use of synthetic dyes has increased. Dye is an integral element used to impart color to textile materials. Wastes generated during the processing and treatment of the dye contain inorganic and organic compounds that are hazardous, thereby posing a serious threat to the ecosystem. It is therefore important to implement cost-efficient and successful measures against these emissions in order to preserve habitats and natural resources. In this context, biodegradation by fungi or mycoremediation of dyes using potential fungi is a fairly inexpensive and environmental friendly method for decomposing or mineralizing barely or less decaying dye compounds. Fungi play a crucial role in degrading and decolorizing organic dyes by enzymes and processes such as absorption, adsorption and aggregation of effluent colorants. The factors affecting the decolorization and biodegradation of dye compounds through fungal bioremediation, such as pH, temperature, dye concentration, agitation, effects of carbon and nitrogen sources, dye structure, enzymes, electron donor and redox mediators are discussed in this review. The review also includes a summary on the mechanism and kinetics of dye degradation as well as recent advances and future perspectives in mycoremediation of dyes.
