AI Technical Summary
Existing natural peroxidases (such as horseradish peroxidase HRP) have low catalytic efficiency and poor stability, making it difficult to effectively degrade phenolic compounds. They are also easily inactivated in industrial wastewater, and traditional chemical oxidation methods pose a risk of secondary pollution.
Peroxidase POD-8 was obtained through gene synthesis and recombinant expression. Its protein structure was predicted using AlphaFold and expressed in Escherichia coli. It was purified using a His-SUMO tag. The enzyme activity and stability towards different substrates, the optimal pH and temperature, and the metal ion concentration were explored for application in dye wastewater treatment.
POD-8 has high enzyme activity and stability towards 2,6-DMP, is tolerant to a variety of metal ions, and can effectively decolorize a variety of dyes, especially Congo red and amino black 10B, with a decolorization rate of up to 25%, showing excellent application prospects in dye wastewater treatment.
