Summary: In this study, laccase was immobilized into amorphous zeolitic imidazolate frameworks-8 (aZIF-8) using a simple in situ encapsulation method, and the synthesized Lac@aZIF-8 biocomposites were used for the removal of Reactive Blue 19 (RB 19). The mesoporous structure endowed the immobilized laccase with higher substrate affinity. The Lac@aZIF-8 exhibited higher thermo-tolerant performance, wider pH range, better storage stability, and reusability compared to free laccase. The Lac@aZIF-8 biocomposites showed excellent performance in the removal of RB 19.

Summary: In this study, sustainable adsorbents made from graphene oxide and other materials were synthesized and demonstrated for the removal of water-soluble dyes. The adsorbents showed promising adsorption capabilities and their performance was optimized by studying the effects of pH, adsorbent dosage, and temperature. The study suggests that the developed nanocomposites have a significant impact in effectively capturing dyes from aqueous environments.

Summary: Two morphologies of laccase-mineral hybrid complexes, La-HNF and La-HNP, were synthesized using Cu3(PO4)2.3H2O for biodegradation of Evans Blue dye. The successful immobilization of laccase and higher enzymatic activity in hybrid complexes were attributed to in-situ formed Cu3(PO4)2.3H2O crystals. La-HNF showed improved biodegradation efficiency and practicality due to the synergistic effect of immobilized laccase within its 3D hierarchical structure.

Summary: A novel thermostable/halotolerant metagenome-derived laccase, PersiLac2, was purified from tannery wastewater and showed high activity in removing textile dyes over a wide temperature and pH range. It also exhibited tolerance to metal ions and organic solvents, with effective decolorization of various dyes and significant detoxification potential. This enzyme could potentially be used for decolorization/detoxification of wastewater in the future.
