Researchers investigated using laccase from Coriolus versicolor fungus to clean up dyestuffs and dye waste water. They looked at factors like pH and substances that boost or hinder laccase activity. They found that using the fungus's mycelial pellets in repeated batches was cost-effective for laccase production. These pellets could maintain strong laccase activity over multiple uses, lowering enzyme production costs. The researchers successfully removed around 98.5% of Acid Orange dye and 93% of color from dye waste water using laccase. Essentially, the study showed that laccase from this fungus could effectively clean up dye-related pollutants, which could be big for the environment and industry.
