abstract = "Recent technological development has focused on addressing two major global issues: environmental protection and conservation of natural resources. High levels of dye production and use have led to significant environmental concerns due to large quantities of unmanaged colored wastewater. Textile dyes, in particular, are highly reactive and problematic when released into the environment.This study investigates the use of Aspergillus fungi biomass, a byproduct of enzyme production (xylanase, cellulase, amylase, and other hydrolytic enzymes), for removing textile dyes from wastewater. The strains Aspergillus niger, Aspergillus oryzae, Aspergillus welwitschiae, and Aspergillus tubingensis were cultivated on corn meal under optimized conditions for enzyme production. The adsorption capacity of the biomass was tested on eight textile dyes: Bezaktiv Gelb, Procion reactive yellow, Reactive yellow, Golden yellow, Procion amber, Congo red, Reactive black 5, and Remazol brilliant blue.The best results were achieved with Aspergillus oryzae biomass, particularly for Reactive black 5. Optimal adsorption conditions identified by DoE were pH 4-5 and a temperature of 25°C. Within the first hour, approximately 90% of the dye (2.16 mg/g biomass) was adsorbed, and after 24 hours, over 99% was adsorbed (2.4 mg/g biomass).The findings demonstrate that post-enzyme production biomass, typically considered waste, can effectively remove reactive dyes and other xenobiotics from wastewater. This dual benefit reduces waste and mitigates water pollution, contributing significantly to environmental protection.",
