Bioreduction of precious and heavy metals by Candida species under oxidative stress conditions

Bioreduction of precious and heavy metals by Candida species under oxidative stress conditions

Summary The aim of the present work was to evaluate whether Candida species can reduce both precious and toxic pure metals from the respective molecular ions. From these results, the nanoparticles formed were studied using scanning electron microscopy with energy‐dispersive spectroscopy, Raman spect...
