Core Insights - Lignin, a complex polymer found in the cell walls of terrestrial plants, shows broad-spectrum antiviral and antibacterial properties, making it a potential green alternative for synthetic antimicrobial agents in coatings, packaging materials, and disinfectants [1][2] Research Findings - A research team from the University of Eastern Finland successfully extracted high-purity lignin from birch wood chips, wheat straw, and oat husks using a simple water-based extraction method [1] - The study demonstrated that lignin exhibits significant antiviral activity against non-enveloped enteric viruses and good inhibitory effects against enveloped viruses and various bacteria, including Staphylococcus aureus and Escherichia coli [1] Mechanism of Action - Lignin weakens the activity of enteric viruses by stabilizing their structure and causing viral particles to aggregate, which allows the viruses to bind and invade host cells but hinders their replication within the cells [1] - For bacteria, the active chemical groups in lignin can penetrate bacterial cells, leading to impaired bacterial functions [1] Publication and Implications - The related research paper has been published in the latest issue of the International Journal of Biological Macromolecules, highlighting lignin's potential as a safe and sustainable alternative for synthetic antimicrobial agents [2]
