Bitter Gourd peroxidase can effectively remove dyes from tannery effluents. The researchers tested different conditions like pH, temperature, time, and enzyme concentration. They found that the best results were achieved at pH 5.0-6.0, 40°C, in 4 hours, with an enzyme concentration of 0.6 ml. This shows that Bitter Gourd peroxidase is a good option for treating effluents with dyes from tanning industries.
