Fig. 6From: Ochrobactrum sp. MPV1 from a dump of roasted pyrites can be exploited as bacterial catalyst for the biogenesis of selenium and tellurium nanoparticlesTEM micrographs of Ochrobactrum sp. MPV1 exposed to SeO3 2− and TeO3 2−. Cultures were grown in presence of 2 mM SeO3 2− for 24 (a), 48 (b) and 72-h (c, c1) or 0.3 mM TeO3 2− for 24 (d), 48 (e) and 72-h (f, f1)Back to article page
