FTIR analysis of untreated and UMB (at 500 μg/ml) treated MRSE, EPS. (A) Spectra of control and UMB treated MRSE, EPS scanned in the range of 4,000–400 cm⁻¹, specifying the regions corresponding to (i) lipids (3,000–2,800 cm⁻¹); (ii) amide bonds of proteins & peptides (1,700–1,500 cm⁻¹); and (iii) polysaccharides (1,200–900 cm⁻¹). (B) Enlarged images of highlighted spectral regions (i), (ii), and (iii).
