Figure 2From: Se (IV) triggers faster Te (IV) reduction by soil isolates of heterotrophic aerobic bacteria: formation of extracellular SeTe nanospheres Bioreduction of tellurite and nanoparticle formation. Tellurite reduction (a) and glucose degradation (b) by aerobic cultures of soil isolates C4, C6 and C7. SEM microphotograph of culture C4 grown in the absence (c) and in the presence of Te (IV) (d), showing Te nanoparticles, confirmed by SEM-EDX spectral analysis (e).Back to article page
