RESUMO

Chemical agents are effective treatment methods for anthracnose induced by pathogenic Colletotrichum gloeosporioides on Stylosanthes. However, excess consumption of chemical agents destroys the environment, synthetic biology was capable of conquering the issue. The antifungal agent is developed by enclosing a bio-synthesized peptide aptamer with layered montmorillonite via electrostatic interaction. Compared with free peptide aptamer, the nanocomposite exhibits higher antifungal activity against Colletotrichum gloeosporioides, further improving the utilization of peptide aptamer. The nanocomposite killed Colletotrichum gloeosporioides by releasing peptide aptamer after they entered the spore. Moreover, montmorillonite enhances the adhesion ability of peptide aptamer via hydrophobic interactions between nanomaterials and leaves, prolonging the extension time of nanocomposite on leaves. Consequently, 0.1 mg of nanocomposite demonstrates a comparable effect to commercial carbendazim (1 %) to prevent anthracnose on leaves of Stylosanthes induced by HK-04 at room temperature. This work demonstrates an alternative to commercial antifungal agents and proposes a versatile approach to preparing environmental-friendly antifungal agents to inhibit fungal infections on crops.
