Green synthesis of silver nanoparticles using fermentation extracts from a mangrove soil bacterium: morphological characterization, and antifungal activities against rice blast fungus.

ABSTRACT:

Background

Rice blast, caused by Pyricularia oryzae, poses a formidable threat to global rice production. Given that chemical fungicides, one of the important methods used to control rice blast, cause harm to the environment and human health, sustainable alternatives are required. This study aimed to synthesize silver nanoparticles (AgNPs) with antifungal activities against P. oryzae using mangrove soil bacteria, and to evaluate their ecotoxicity.

Results

In this study, AgNPs were synthesized using fermentation extracts from Pseudomonas aeruginosa R64. The resulting nanoparticles (RFE-AgNPs), ranging in size from 4.516 to 37.031 nm, were characterized by UV-visible spectroscopy and high-resolution transmission electron microscopy equipped with energy dispersive spectroscopy.
