Abstract: Microorganisms play an important role in toxic metal remediation through reduction of metal ions. Studies demonstrated that silver ions may be reduced extracellularly using Fusarium oxysporum to generate stable gold or silver nanoparticles in water. These particles can be incorporated in several kinds of materials such as cloths. These cloths with silver nanoparticles are sterile and can be useful in hospitals to prevent or to minimize infection with pathogenic bacteria such as Staphylococcus aureus. In this work, the extracellular production of silver nanoparticles by F oxysporum and its antimicrobial effect when incorporated in cotton fabrics against S. aureus were studied. In addition, all effluent was bioremediated using treatment with C. violaceum. The results showed that cotton fabrics incorporated with silver nanoparticles displayed a significant antibacterial activity against S. aureus. The effluent derived from the process was treated with C. violaceum and exhibited an efficient reduction in the silver nanoparticles concentration. In conclusion, it was demonstrated the application of biological synthesis to silver nanoparticles production and its incorporation in cloths, providing them sterile properties. Moreover, to avoid any damage to the environment the effluent containing silver nanoparticles can be treated with cyanogenic bacterial strains.
