Biosynthesis of Crystalline Silver and Gold Nanoparticles by Extremophilic Yeasts
Influence of silver and gold concentration on (a) yeast growth and (b) in uninoculated growth medium (glucose). Measurements were performed at OD 610 nm and NAUC (net area under curve) values refer to 6 days. Inset: UV-Vis spectra recorded after the reaction of uninoculated growth medium with 1 mM HAuCl4 for 24 h.
