Discussion

Solid-state fermentation yields high laccase and lignin peroxidase from fungal strains, suggesting effective dye degradation methods.

The optimized medium produced laccase at 151.9 U/g and lignin peroxidase at 19.2 U/g, demonstrating effective enzyme production.
Utilizing banana pseudostems as a substrate resulted in significantly higher enzyme activity (49.8 U/g for laccase) compared to other residues.
A two-level full factorial design identified key variables like moisture and pH that significantly impact enzyme production, indicating optimization opportunities.
The crude enzyme effectively degraded dyes with rates exceeding 82%, highlighting practical applications in wastewater treatment.

Flanetraj et al. (2025) studied this question.
