ABSTRACT
Industrial development leads to environmental problems. This is true in large industrial liquid waste management, especially when it involves water contamination in a textile industry by synthetic dyes. This research aims to explore the potential of thermophilic fungi, specifically Aspergillus sp., in bioremediation of methylene blue dye. The study demonstrates high decolorization rates within 96 hours using Aspergillus sp. fungi. Follow up test biosorption by Fourier Transform Infrared analysis carried out further confirms successful breakdown of dye molecules, showcasing the dual role of thermophilic fungi in effective wastewater treatment. This research provides insights into sustainable solutions in textile wastewater treatment and calls for further exploration in bioremediation of other contaminants. The four fungal strains: LBKURCC304, LBKURCC305, LBKURCC307, and LBKURCC308, were evaluated for their decolorization efficiency. LBKURCC304 and LBKURCC307 demonstrated the highest performance, achieving the decolorization of 48.10% and 53.81%, respectively, within 96 hours under acidic conditions (pH 4.5). The results highlight the dual functional capability of the thermophilic fungi to achieve both the enzymatic and physical removal of pollutants. This study underscores the significant potential of thermophilic fungi Aspergillus sp. in developing sustainable wastewater treatment systems, particularly for the textile industry. The findings contribute to the advancement of microbial-based bioremediation, presenting an environmentally friendly approach to mitigating industrial effluent pollution. However, challenges remain, including optimizing operational parameters for large-scale applications and exploring the fungi's capacity to degrade a broader spectrum of synthetic dyes. Overall, this work paves the way for integrating microbial bioremediation into sustainable environmental management practices, offering a practical solution to one of the most pressing issues of industrialization.
