Secondary metabolites from trichoderma strains as natural antifungal agents
Vexxel Biotech presents a bioactive solution using secondary metabolites from Trichoderma afroharzianum strains as natural antifungal agents. These compounds, effective against Fusarium and Aspergillus, offer potential control of rice blast without phytotoxicity.
Overview
Vexxel Biotech is exploring the antifungal properties of secondary metabolites derived from Trichoderma afroharzianum strains. These metabolites, including peptaibols and phenolic derivatives, have demonstrated significant in vitro antifungal activity against pathogens such as Fusarium graminearum and Aspergillus brasiliensis, while also promoting root growth in lettuce without any observed phytotoxic effects. The combination of these properties positions this solution as a promising candidate for sustainable agricultural biocontrol, particularly in managing rice blast disease caused by Magnaporthe oryzae.
Technical specifications
Key features:
- Bioactivity: Contains 21 characterized compounds with known antifungal properties, including peptaibols and phenolic derivatives.
- Efficacy: Proven in vitro activity against Fusarium and Aspergillus species.
- Plant Compatibility: Promotes plant growth without phytotoxic effects, as evidenced in lettuce trials.
- Environmental Adaptability: Derived from native, soil-adapted Trichoderma strains, enhancing environmental compatibility and sustainability.
- Potential for Rice Blast Control: Chemical profile suggests effectiveness against Magnaporthe oryzae, supported by literature on similar metabolites.
Technology readiness level
The current readiness level of this technology is TRL 3, indicating that the solution has been demonstrated in a laboratory environment. Future validation efforts will focus on further in vitro testing against Magnaporthe oryzae, as well as field trials to assess phytotoxicity and protective effects on rice seedlings.
