Biofabrication of titanium dioxide nanoparticles by fungi isolated from soil

Abstract

In the present study , the biosynthesis of  TiO₂ nanoparticles were included by fungi  Fusarium oxysporum , the particle size were 30-90 nm , fungi Fusarium oxysporum was isolated from soil using serial dilution technique , biomass was harvested and used to biosynthesized TiO₂ nanoparticles . The biosynthesis of  TiO₂ nanoparticles was characterized by UV  Vis. Spectroscopy (UV) , X-ray diffraction (XRD) , atomic force microscope (AFM) and scanning electron microscope (SEM) studies .The biosynthesized TiO₂ nanoparticles were tested against gram  Positive and gram  negative bacteria .  results showed that TiO₂ nanoparticals have a remarkable antibacterial activity against gram  Positive and gram  negative bacteria .
