Fig. 12From: Ochrobactrum sp. MPV1 from a dump of roasted pyrites can be exploited as bacterial catalyst for the biogenesis of selenium and tellurium nanoparticlesFTIR spectra of biogenic SeNPs and TeNPs extracted from Ochrobactrum sp. MPV1. Both SeNPs and TeNPs were extracted after 24 (T1) and 48-h (T2). Spectra were acquired in the 4000–2500 cm−1 (a) and 2000–700 cm−1 (b) infrared regions. SeNPs-T1 in dark red, SeNPs-T2 in light red, TeNPs-T1 in black, TeNPs-T2 in grey. SeNPs-T1 and SeNPs-T2 spectra are overlappedBack to article page
