Screening for Ligninolytic Enzymes from Autochthonous Fungi and Applications for Decolorization of Remazole Marine Blue

Summary

This research identified new fungi capable of producing enzymes that can break down tough plant materials and degrade industrial dyes. These findings have important real-world applications: • Could help develop more environmentally friendly processes for treating textile industry wastewater • May lead to improved methods for paper production and processing • Could contribute to the development of natural alternatives for chemical processes in various industries • Offers potential solutions for breaking down plant waste materials • May help reduce environmental pollution through biological treatment methods

Background

Basidiomycetes are a major group of fungi that include white rot, brown rot and leaf litter fungi. White-rot fungi are unique in their ability to efficiently mineralize lignin through ligninolytic enzymes. These enzymes include laccase, manganese peroxidase, and lignin peroxidase, which are involved in breaking down lignin and have potential applications in various industrial and biotechnological processes.

Objective

To screen and identify new fungal strains capable of producing ligninolytic enzymes and evaluate their potential for industrial applications. The study aimed to develop a rapid screening method using fresh fruit body extracts and test the isolated strains’ ability to decolorize textile dyes.

Results

Several fungal strains showed significant ligninolytic enzyme activity, with Trametes versicolor showing the highest levels of both laccase and manganese peroxidase activities. Previously unreported strains like Lyophyllum subglobisporium, Inocybe longicystis, and Ramaria stricta were found to produce these enzymes. Ganoderma carnosum and Trametes versicolor demonstrated effective decolorization of Remazol Marine Blue dye.

Conclusion

Fresh fruit body extracts can be used as a rapid primary screening method for identifying new ligninolytic enzyme-producing fungi. The study identified several novel fungal strains with potential industrial applications in enzyme production and dye decolorization.
