Abstract
The aim of the present work was the development of a new biological method for the treatment of textile industry effluents, which is cheaper, more profitable, and eco-friendly. This method is essentially based on the synthesis of dye-fixing peptides. The use of peptides synthesized via a solid-phase synthesis to fix a reference textile dye like “Cibacron blue” (CB) and the performance analysis of binding assays were the main objectives of this study. For this reason, two peptides P1 (NH2-C-G-G-W-R-S-Q-N-Q-G-NH2) and P2 (NH2-C-G-G-R-R-Y-Q-P-D-S-NH2) binding with the CB dye were synthesized by the solid-phase peptide synthesis (SPPS) technique. The obtained results showed significant fixation yields of CB-peptides of 91.5% and 45.9%, respectively, and consequently, their interesting potential as a tool for a new biochemical method in the pollution prevention of textile wastewater.

Summary
Peptides Fixing Industrial Textile Dyes: A New Biochemical Method in Wastewater Treatment. Adsorption is an efficient treatment for removing organic compounds, especially when the molecular weight of the effluent is high and the polarity is low It is a process where a solid is utilized to receive the dye of water, activated carbon being the most commonly used solid. E objective of this study is the development of a new biological approach which is more suitable in terms of costeffectiveness, pollutant removal efficiency, and recyclability and inexpensive, effective, and eco-friendly (biodegradable) for the treatment of effluents of the textile industry. To our knowledge, this is the first report on the textile effluent treatments using peptides. E peptide-dye interaction is governed by low-energy type links (electrostatic, van der Walls, hydrophobic, Pi, and ionic). is mechanism is the same as the mechanism of interaction of antibodies with antigens or the interaction of a receptor with a ligand or even the interaction of a substrate with an enzyme. is interaction is very specific, that is, a peptide may interact with a dye or a dye family. e affinity between the peptide and the dye is very important, and it can approach the affinity of a substrate to an enzyme
