Improved biosynthesis and characteristics of silver nanoparticles using marine endophytic fungi exposed to hypo-osmotic stress.

ABSTRACT: Silver nanoparticles (AgNPs) are valued for their unique properties and can be synthesized biologically, offering a greener alternative to traditional methods. This study assessed the potential of cell-free filtrates (CFFs) of seaweed-associated marine fungi to produce AgNPs. More specifically, Talaromyces pinophilus, Aspergillus fructus, Stemphylium gracilariae, Purpureocillium lilacinum, Microascus croci, Penicillium toxicarium, Exophiala mesophila, and Emericellopsis maritima, when cultured in media prepared with artificial seawater or distilled water (hypo-osmotic conditions) as a possible stress inducer. Optimization of the reaction conditions including changes in pH, temperature, reaction time, and the concentration of AgNO₃ and CFF were evaluated for obtaining high relati
