Figure 5From: Delayed formation of zero-valent selenium nanoparticles by Bacillus mycoides SeITE01 as a consequence of selenite reduction under aerobic conditions TEM micrographs and EDAX spectra of B. mycoides SeITE01 cultures grown in presence of 2 mM SeO 3 2− registered at different incubation times. 12 (A and B) and 24 (C and D) hours. Arrows point electron-dense particles (indicated by number 1 and 2), whose corresponding EDAX spectra are given on the bottom of the micrographs (E and F).Back to article page
