Abstract :

 The development of eco–friendly and economical technologies in material synthesis is of considerable importance  to expand their biological applications. Nowadays, a variety of inorganic nanoparticles have been synthesized using  chemical methods and their applications in many cutting–edge technological areas have been explored. The current reports and future prospects for the synthesis of metal nanoparticles by microorganisms are scanty due to the oligo dynamic property of metals. The present study  highlights the bio–synthesis of metal nanoparticles from metal resistance fungal species isolates from soybean rhizosphere. Total 22 different  fungal strains were isolated and identified belonging to; Aspergillus, Penicillium and Fusarium species respectively. All the isolates were  tested for extracellular nanoparticle synthesis. The metal nanoparticles were detected by biological reduction process and further characterized adopting spectrophotometry for monitoring surface plasmon resonance. Out of 22 fungal isolates, 5 isolates showed the considerable  synthesis of Ag, Zn, Mn and Cu nanoparticles respectively this indicates the potential of fungi to reduce the metal salts. The present study  indicates the possibilities of fungal transformation method for the synthesis of nanoparticles as an effective and economical method over  chemical synthesis.
