چکیده مقاله:

  ABSTRACT             Background and objectives: Silver nanoparticles (AgNPs) are major nanomaterials with a variety of applications. The synthesis of nanoparticles by conventional methods is challenging and often requires use of hazardous chemicals. Therefore, there is a growing need for development of environmentally and economically friendly processes for the synthesis of nanoparticles. This study aimed at biosynthesis of AgNPs using a filamentous fungus; Fusarium solani.             Methods: Twenty-four Fusarium isolates were found from several soil samples collected from depth of 1-10 cm. All isolates were identified as F. solani based on morphological characteristics. The synthesis of nanoparticles were evaluated after 24, 48, 72 hours of culture. AgNPs were characterized using UV-visible spectroscopy and transmission electron microscopy.             Results: The synthesized AgNps showed maximum absorbance peak at 420 nm after 72 hours. Moreover, most AgNps were spherical with diameter of between 20 and 40 nm.             Conclusion: In this study, we introduced a simple biological process for biosynthesis of AgNPs using F. solani isolates from soil samples. The results indicate that fungi may be suitable for safe and cost-effective production of AgNPs.             Keywords: Fungi; Fusarium; Nanoparticles; Nanotechnology.

Allergens from Fusarium solani identified by immunoblotting in asthma patients In Iran.

We extracted Fusarium solani antigens to evaluate specific anti-F. solani IgE in fifty-one patients with asthma (33 men and 18 women) and in 22 non-atopic healthy subjects (15 men and 7 women). F. solani strains were cultured in Sabouraud glucose agar and subjected to cell disruption using the freeze-and-thaw method. The obtained cytoplasmic extracts were analysed using sodium dodecyl sulphate-...

Mechanistic aspects of biosynthesis of silver nanoparticles by several Fusarium oxysporum strains

Extracellular production of metal nanoparticles by several strains of the fungus Fusarium oxysporum was carried out. It was found that aqueous silver ions when exposed to several Fusarium oxysporum strains are reduced in solution, thereby leading to the formation of silver hydrosol. The silver nanoparticles were in the range of 20-50 nm in dimensions. The reduction of the metal ions occurs by a...
