Should manufacturers prioritize eco-friendly enzymes over traditional chemicals for textile dyeing and printing?
Researchers have identified a fungus strain, Trichoderma viride lac418, which produces an enzyme capable of enhancing color affinity for cotton and viscose fabrics. This discovery provides a potential path toward replacing toxic, carcinogenic mordants currently used in industrial textile dyeing.
Why it matters
Traditional chemical mordants in textile production are often hazardous to both human health and the environment. This biological alternative utilizes natural processes to bind dyes effectively, potentially reducing the industry's reliance on carcinogenic substances.
The enzyme derived from Trichoderma viride lac418 achieves maximum activity at 60 °C and pH 5.0, with an activation energy of 7.7 kJ/mol. Experimental trials utilized a 2:1 dye-to-enzyme ratio to optimize color fixation on cotton and viscose samples.

Trichoderma viride lac418
This is a specific strain of fungus identified for its ability to produce enzymes useful in industrial biochemical applications.
The details
The fungus, which was isolated from rotten wood, utilizes laccase enzymes to oxidize phenolic hydroxyl groups in dyes, triggering polymerization that secures the color to the fabric. Studies identified rutin and rosmarinic acid as the compounds with the strongest binding affinity to this specific enzyme.
Timeline
The findings were formally published on October 4, 2026.
The Big Picture
This discovery marks a shift in textile chemistry that aligns with the European Chemicals Agency's restrictions on hazardous textile mordants. It disproves the necessity of using toxic heavy metal compounds for dye fixation by demonstrating the viability of fungal enzymatic alternatives.
If successfully commercialized, this technology could lead to a new generation of eco-friendly clothing produced without the use of harsh chemical fixatives. Consumers may eventually see products marketed as sustainably dyed, potentially reducing allergic reactions and environmental runoff associated with traditional mordants.
The takeaway
The move toward bio-enzymatic dye fixation represents a critical step in cleaning up the textile supply chain. Industry stakeholders should look for opportunities to integrate these fungal-derived enzymes to meet tightening environmental safety standards.
