Özet

The waste biomass of grape pomace was utilized for the immobilization of model fungal cells (Thamnidium elegans) providing a green, innovative, and practical biocomposite for efficient biodecolorization of a model reactive dye (Reactive Yellow 2). Appreciable decolorization capacity at optimized conditions was observed as q(max)=151.0 mg g(-1) with the suggested biocomposite (TECWGP). During the batch process, the biocomposite exhibited the highest dye removal of 98.57 % in the RY2-contaminated solutions. The biosorptive decolorization process was the best predicted by the Langmuir isotherm and the pseudo-second-order kinetic models. The possible interactions between RY2 and TECWGP were also examined. Synthetic wastewater treatment experiments indicated that TECWGP has a good decolorization potential. Overall, the findings indicated that TECWGP could be a good alternative to synthetic materials for the treatment of reactive dye-contaminated aqueous phase. Furthermore, the utilization of agro-industrial waste to support fungal cells contributes to the growth of a solid circular bio-based economy.
