Studies from Institute for Biochemistry in the Area of Nanoparticles Reported (Enzymatic formation of gold nanoparticles by submerged culture of the basidiomycete Lentinus edodes)

By a News Reporter-Staff News Editor at Biotech Week -- Current study results on Nanoparticles have been published. According to news reporting from Saratov, Russia, by NewsRx journalists, research stated, "We report for the first time that the medicinal basidiomycete Lentinus edodes can reduce Au(III) from chloroauric acid (HAuCl4) to elemental Au [Au(0)], forming nanoparticles."

The news correspondents obtained a quote from the research from Institute for Biochemistry, "Several methods, including transmission electron microscopy, electron energy loss spectroscopy, X-ray fluorescence, and dynamic light scattering, were used to show that when the fungus was grown submerged, colloidal gold accumulated on the surface of and inside the mycelia( hyphae as electron-dense particles mostly spherical in shape, with sizes ranging from 5 to 50 nm. Homogeneous proteins (the fungal enzymes laccase, tyrosinase, and Mn-peroxidase) were found for the first time to be involved in the reduction of Au(III) to Au(0) from HAuCl4."

According to the news reporters, the research concluded: "A possible mechanism forming Au nanoparticles is discussed."
