Abstract
Shewanella oneidensis (S. oneidensis) MR-1 is a metal-reducing bacterium that can bio-reduce the carcinogenic hexavalent chromium (Cr6+) to the less toxic trivalent Cr3+. Bio-reduction is assisted by the protective role of Mn-ferrite NPs to bacteria.
Key findings
- Mn-ferrite nanoparticles protect S. oneidensis MR-1 from chromate toxicity
- Bio-reduction of Cr6+ to Cr3+ is enhanced in the presence of Mn-ferrite nanoparticles
- Mn-ferrite nanoparticles play a protective role in the bio-reduction process
