Bacillus licheniformis causes losses in the in vitro cultivation of these plants. The use of silver nanoparticles (AgNPs) biosynthesized from plant extracts is an alternative to control the contamination caused by this microorganism. The objective of this study was to characterize AgNPs biosynthesized from three Agave genotypes and to evaluate their antibacterial activity. AgNPs were characterized using UV-Vis spectroscopic analysis, transmission electron microscopy, and energy dispersive X-ray spectroscopy. AgNPs biosynthesized from A. tequilana and A. cupreata with a smaller size showed better antibacterial efficacy against B. licheniformis than AgNPs with a larger size, biosynthesized from A. salmiana. Our results provide an environmentally friendly, simple, and low-cost method for the biosynthesis of AgNPs with antibacterial activity.
