Abstract
BACKGROUND: The application of biocontrol agents offers a promising strategy for managing pear anthracnose, yet their efficacy is often limited by unstable colonization on fruit surfaces. RESULTS: Here, we isolated Paenibacillus polymyxa JF_P68, which exhibits strong inhibitory activity against Colletotrichum fructicola. To enhance its environmental tolerance, we developed a hyaluronic acid (HA)-functionalized nanoarmor using a layer-by-layer coating technique. This nanoarmor significantly improved the JF_P68's resistance to ultraviolet radiation and oxidative stress. In vivo trials demonstrated that nanoarmor-equipped JF_P68 reduced pear anthracnose lesion diameters by 43.5% and maintained higher colonization levels on fruit surfaces. Genome analysis revealed 20 biosynthetic gene clusters, including novel antimicrobial candidates, underpinning its broad-spectrum antifungal activity. CONCLUSION: The single-cell coating method, characterized by simplicity, scalability, and biocompatibility, significantly enhances the persistence and efficacy of biocontrol agents. This study provides a novel approach to improving the biological control of pear anthracnose. © 2025 Society of Chemical Industry.
