Mushroom enzymes like laccase and tyrosinase actively transformed hair dye chemicals such as aminophenols and phenylenediamines, which make up a large share of salon wastewater pollutants. Standard treatment systems remove only ~60% of these compounds, leaving behind toxic residues that fungi can chemically alter. However, this process can create more stable and potentially harmful byproducts, highlighting both the power and limits of fungi in pollution cleanup.
