TITLE:

EVALUATION OF THE BIOTECHNOLOGICAL POTENTIAL OF Aspergillus tamarii kita UCP1279 IN THE BIOREMEDIATION OF TEXTILE EFFLUENTS

KEY WORDS:

Bioremediation, azo dyes, Aspergillus tamarii kita, biomass

SUMMARY:

The textile industry is one of the largest consumers of water, which in turn uses a large amount of dyes in the fabric dyeing process, thus releasing massive volumes of effluents containing numerous salts, pigments, heavy metals, toxic agents, as well as substances colors that reduce the transparency and dispersion of oxygen in the system, harming both aquatic biota and riverine populations. Due to structural and molecular complexity, azo dyes are resistant to various physical and chemical treatments. Therefore, the development of efficient and low-cost control methods against this pollution is vital to protect ecosystems and natural resources. In this sense, recent advances in science have boosted bioremediation as a potential alternative to conventional treatment methods, in terms of cost-effectiveness and sustainability. The application of filamentous fungi stands out among the microorganisms used, as their biosorption mechanism does not only use biodegradation as a method of remediation of these dyes. Biosorption as an adsorption process on biological materials, including living and dead, is most recently considered for the removal of pollutants. Therefore, the present study aimed to evaluate the biotechnological potential of the fungus Aspergillus tamarii kita in the bioremediation of azo dyes frequently used in the garment industry in Agreste Pernambucano. Maximum discoloration (100%) of Direct Black 22 and Marinho Direct 2R was observed in a short time, while the concentration of both dyes remained at 50mg/L. In summary, our study demonstrated that Aspergillus tamarii kita may be well suited for potential applications in textile effluent bioremediation.
