“…There have been several suggested RB5 breakdown pathways using different fungi, predominantly using liquid culture to assess the potential of using fungi as bioremediation agents for dye-contaminated water. None of the breakdown products suggested for pathways in Aspergillus 28 or the basidiomycetous wood decay specialist Trametes 18 were identified in the samples in this study. Somewhat surprisingly, the RB5 breakdown metabolites identified by 24 using the ascomycete Trichoderma atroviride did provide a match (Table S1 ).…”

Textile waste contains both natural fibres such as cotton and bamboo viscose, and synthetic fibres such as elastane and polyester. As a complex mixture, textiles present a challenging pollution issue as breakdown in landfill results in microplastics entering water and soil environments, and incineration results in particulate air pollution. Here the use of edible fungi as bioremediation agents of waste textiles is described for the first time. Three species of filamentous fungi were shown to colonise and grow on mixed fibre textile waste (underpants made from 28% cotton: 68% bamboo viscose: 4% elastane). All three fungi were able to metabolise the common textile dye Reactive Black 5 to some extent. The metabolome was captured to elucidate the dye remediation pathway utilized and to characterise the volatiles released during bioremediation with a view to assessing the safety profile of this process for future industrial applications. The results suggest that edible fungi may be cultivated on textiles, and that some interesting and useful compounds may be produced in the process. This has great biotechnological potential. No mushrooms were produced in this study, suggesting that further work will be needed to optimise conditions for crop production from waste textiles.

“…In silico docking experiments have suggested laccases as being of paramount importance in the biodegradation of RB5 [ 38 ] although peroxidases have also been suggested as promising enzymes to explore [ 42 ]. Where a fungal biodegradation mechanism for RB5 has been elucidated and the end point metabolites captured, there has been a demonstration of limited toxicity to plant seeds [ 21 , 43 ] and reduced cytotoxicity to human cell lines [ 38 ].…”

Textile waste contributes to the pollution of both terrestrial and aquatic ecosystems. While natural textile fibres are known to be biodegraded by microbes, the vast majority of textiles now contain a mixture of processed plant-derived polymers and synthetic materials generated from petroleum and are commonly dyed with azo dyes. This presents a complex recycling problem as the separation of threads and removal of dye are challenging and costly. As a result, the majority of textile waste is sent to landfill or incinerated. This project sought to assess the potential of fungal bioremediation of textile-based dye as a step towards sustainable and environmentally-friendly means of disposal of textile waste. Successful development of an agar-independent microcosm enabled the assessment of the ability of two fungal species to grow on a range of textiles containing an increasing percentage of elastane. The white rot fungus Hypholoma fasciculare was shown to grow well on semi-synthetic textiles, and for the first time, bioremediation of dye from textiles was demonstrated. Volatile analysis enabled preliminary assessment of the safety profile of this process and showed that industrial scale-up may require consideration of volatile capture in the design process. This study is the first to address the potential of fungi as bioremediation agents for solid textile waste, and the results suggest this is an avenue worthy of further exploration.

“…Therefore, it is necessary to constantly monitor the concentration of these pollutants in wastewater and to implement effective and cost-effective treatment methods that ensure their removal from the effluent before it rises above critical values ( Jawad and Abdulhameed, 2020 ; Dehmani et al, 2021 ; Loutfi et al, 2023 ). For this aim, the several physical, chemical, and biological methods were developed and used to treat of dye-containing wastewater such as adsorption ( Kim et al, 2023 ), membrane filtration ( Zhao et al, 2021 ), ion exchange ( Joseph et al, 2020 ), photocatalytic degradation ( Fu and Ren, 2020 ), coagulation-flocculation ( Ihaddaden et al, 2022 ), electro-fenton ( Jinisha et al, 2018 ), anodic oxidation ( Mo et al, 2020 ), electrocoagulation ( El-Ashtoukhy and Amin, 2010 ), advanced oxidation ( Dadban Shahamat et al, 2022 ), reverse osmosis ( Nataraj et al, 2009 ), enzyme ( Riegas-Villalobos et al, 2020 ), bacteria ( Srinivasan et al, 2022 ), yeast ( Martorell et al, 2012 ), fungal ( Gul et al, 2023 ), and algae ( Zhang et al, 2022 ) assisted degradation ( Al-Tohamy et al, 2022 ).…”

The commercial activated carbon commonly uses to reduce of dye amount in the textile industry effluents. In this study has focused on the use of a natural clay sample as low cost but potential adsorbent. For this purpose the adsorption of commercial textile dyes, Astrazon Red FBL and Astrazon Blue FGRL, onto clay was investigated. The physicochemical and topographic characteristics of natural clay sample were determined by scanning electron microscopy (SEM), X-Ray fluorescence spectrometry (XRF), X-Ray diffraction (XRD), thermogravimetric analysis (TGA), and cation exchange capacity measurements. It was determined that the major clay mineral was smectite with partial impurities. The effects of several operational parameters such as contact time, initial dye concentration, temperature, and adsorbent dosage on the adsorption process were evaluated. The adsorption kinetics was interpreted with pseudo-first order, pseudo-second order, and intra-particle diffusion models. The equilibrium adsorption data were analyzed using Langmuir, Freundlich, Redlich-Peterson, and Temkin isotherm models. It was determined that the adsorption equilibrium was reached in the first 60 min for each dye. The amount of adsorbed dyes onto clay decreased with increasing temperature, similarly, it decreased with increasing sorbent dosage. The kinetic data were well described by pseudo-second order kinetic model, and adsorption equilibrium data was followed both Langmuir and Redlich-Peterson models for each dyes. The adsorption enthalpy and entropy values were calculated as −10.7 kJ.mol−1 and −13.21 J.mol−1.K−1 for astrazon red and those for astrazon blue −11.65 kJ.mol−1 and 37.4 J.mol−1.K−1, respectively. The experimental results support that the physical interactions between clay particles and dye molecules have an important role for the spontaneous adsorption of textile dyes onto the clay. This study revealed that clay could effectively be used as an alternative adsorbent with high removal percentages of astrazon red and astrazon blue.
