Strain-Specific Bacillus subtilis-Derived Silver Nanoparticles for Effective Antibacterial Activity Against Multidrug-Resistant Pathogens: In Vitro Model

This study highlights the superior NPs biosynthesis capacity and antibacterial potency of the wild-type strain <i>B. subtilis</i> 3610 compared to the domesticated laboratory strain 168. The findings emphasize the critical influence of strain-specific genetic and metabolic traits in optimizing microbial nanomaterial production and position 3610-derived AgNPs as promising candidates for biomedical applications.
