Area of Science:

• Environmental Science
• Biochemistry
• Mycology

Background:

• 2,4-D (2,4-dichlorophenoxyacetic acid) is a widely used herbicide with environmental persistence and potential health risks.
• Efficient and sustainable detoxification strategies for 2,4-D are crucial for environmental safety.

Purpose of the Study:

• To critically review fungal biodegradation pathways of 2,4-D.
• To focus on enzymatic mechanisms involving laccases, manganese peroxidases, and lignin peroxidases.
• To explore environmental factors influencing enzyme activity and potential applications of metabolites.

Main Methods:

• Review of existing literature on fungal 2,4-D biodegradation.
• Analysis of enzymatic pathways, specifically laccases and peroxidases.
• Investigation of environmental factors (pH, temperature, nutrients) affecting enzyme function.

Main Results:

• Laccases and peroxidases are key enzymes in fungal 2,4-D degradation, initiating oxidation and bond cleavage.
• Synergistic enzyme activity enhances degradation efficiency and broadens substrate range.
• Environmental factors significantly influence enzyme activity and stability.

Conclusions:

• Fungal enzymatic systems offer a promising avenue for 2,4-D bioremediation.
• Understanding enzymatic mechanisms and environmental influences is key to optimizing degradation.
• Intermediate metabolites may have potential for valorization in other industries.
