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

Figure 5

Dye-peptide binding test: Once the support is ready, a contact with the peptide in the basic medium allows their binding by means of disulfide bond formation between the cysteine of the support and the cysteine of the peptide. A solution of “Cibacron blue” at a concentration of 10 mg/L for 48 h is then contacted with the support-bound peptide, and finally, the OD of the filtrate is measured.
