A team of Vietnamese researchers has discovered a sustainable way to synthesize silver nanoparticles using a native bacterial strain, Pantoea coffeiphila LV-V3, isolated from the Central Highlands jungle. By optimizing the biosynthesis parameters—AgNO₃/CFFB ratio of 3:1, 1.5 mM AgNO₃ concentration, 70 °C temperature, and pH 6—the team achieved an efficient and stable nanoparticle yield.
Characterization revealed uniform, spherical nanoparticles (≈ 8.5 nm) with excellent stability over three months. These biogenic AgNPs displayed remarkable nematicidal activity, significantly inhibiting both egg hatching and juvenile stages of black pepper nematodes.
Microscopic and spectroscopic analyses confirmed the nanoparticles’ ability to penetrate nematode eggs and juveniles, explaining their potent biological action. This study marks the first report of P. coffeiphila being used for silver nanoparticle biosynthesis, highlighting its potential as a green, low-cost, and scalable approach to managing plant-parasitic nematodes in sustainable agriculture.
