Peptides Fixing Industrial Textile Dyes: A New Biochemical Method in Wastewater Treatment

الملخص EN

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.
