Goal
Use fungal mycelium and mushroom extracts to clean polluted environments, control pests, and provide health-beneficial compounds.
Problem
Environmental contamination (waterborne pathogens, chemical pollutants), agricultural pests, viral diseases in humans and insects, and loss of biodiversity.
Concept Summary
Fungal mycelium can be cultivated on organic substrates (e.g., wood chips, straw) to filter pathogens from water (mycofiltration), degrade chemicals, and produce bioactive compounds that modulate immunity or act as antivirals. Patented fungal strains can also act as biopesticides or break down neurotoxins.
Principles
- Mycelial growth on porous substrates
- Enzymatic degradation of organic pollutants
- Bioaccumulation and filtration of pathogens
- Production of beta-glucans and antiviral secondary metabolites
- Biopesticidal attraction of insects
Scientific Domains
Materials
- Mycelium (various fungal species)
- Wood chips
- Straw
- Saw dust
- Fermented substrate
- Ethanol extracts
Mechanisms of Action
- Enzymatic breakdown of contaminants
- Adsorption of bacteria and viruses onto hyphal mats
- Synthesis of antiviral coumarins and polysaccharides
- Attraction of insects to toxic fungal metabolites
Applications
- Water purification
- Agricultural pest control
- Human dietary supplements
- Antiviral therapeutics
- Soil remediation
Claimed Performance
79-fold reduction in deformed wing virus and 45,000-fold reduction in Lake Sinai virus in honey bees; >90 % reduction in thermotolerant coliform export from mycofiltration columns; significant immune-activating activity of Trametes versicolor mycelium and fermented substrate.
Experimental Evidence
In vitro immune-modulating activity of Trametes versicolor mycelium; field trials showing viral load reductions in honey bee colonies fed Ganoderma resinaceum extract; mycofiltration column tests removing ~20 % E. coli and >90 % coliforms on wood-chip media.
Limitations
- Scale-up of mycelial reactors
- Variability of fungal strain performance
- Regulatory approval for medicinal claims
- Dependence on suitable substrate supply
