Gallium-binding peptides as a tool for the sustainable treatment of industrial waste streams

نویسندگان

چکیده

Here we provide a proof of principle for an application-oriented concept the peptide-based recovery gallium in industrial wastewater, which was supported by biosorption studies with real wastewater sample. We investigated interaction gallium-binding peptides TMHHAAIAHPPH, NYLPHQSSSPSR, SQALSTSRQDLR, HTQHIQSDDHLA, and NDLQRHRLTAGP arsenic through different experimental computational approaches. Data obtained from isothermal titration microcalorimetry indicated competitive influence presence acetate ions exothermic contribution to otherwise endothermic peptide interactions. For stabilizing on metal found. Peptide NYLPHQSSSPSR showed highest affinity ITC studies. Computational modeling used determine parameters explain possible binding mechanism. Furthermore, were immobilized polystyrene beads. Thus, created novel exceptionally robust material aqueous solution.
