Across Multiple Industries With increasingly stringent environmental regulations and rising costs of chemical agents, industries such as papermaking, textiles, and wastewater treatment are trapped in the dual dilemma of "difficulty in meeting standards and low profitability". As a "natural green catalyst", laccase is addressing these pain points at the source and has become a core choice for industries to reduce costs and carbon emissions.
Laccase is not an ordinary enzyme, but a type of copper-containing polyphenol oxidase. Its core advantages stand in sharp contrast to traditional chemical treatment methods:
It can catalyze reactions under normal temperature and pressure without the need for high temperature or high pressure. Moreover, it can directionally oxidize refractory substances such as aromatic compounds and lignin without damaging target products.
vs. Traditional Chemical Agents:Traditional treatment uses sodium hypochlorite, sulfuric acid, etc., which generate highly toxic wastewater; after laccase catalysis, only water and harmless small molecules are produced, directly reducing end-of-pipe treatment costs.

Identify Target Substrates: Precisely target phenolic pollutants in wastewater, lignin in papermaking raw materials, and chromophores in textile dyes.
Catalysis by Copper Ion Clusters: The four copper ions in the enzyme molecule act as active centers, oxidizing substrates via single-electron transfer and converting refractory substances into easily decomposable free radicals.
Scenario Verification: In the papermaking industry, replacing chemical bleaching with laccase can reduce the use of chlorine-based agents by 60% and lower the chemical oxygen demand (COD) of wastewater by 45%; in leather tanning, using laccase reduces chromium ion usage by 30% while making the finished product more flexible.
3.
Environmental Protection Field: Treats wastewater from pharmaceuticals, printing and dyeing, and coking industries, degrading toxic substances. The treatment cost is 20% lower than that of activated carbon adsorption.
Papermaking Industry: Used in biological pulping and bleaching, reducing chemical agent consumption while improving pulp whiteness.
Textile Industry: Applied in dye decolorization and stone washing of denim, replacing potassium permanganate and avoiding damage to fabric strength.
