ANNOVA-PCA score plots of ATR-FTIR spectra of Mucor circinelloides fungus, spectral regions such as lipid regions (A) and (B)—3050–2800 cm⁻¹ and 1800–1700 cm⁻¹, protein (C) and (D)—1700–1500 cm⁻¹, mixed (E) and (F)—1500–1200 cm⁻¹, polysaccharide + polyphosphate region (G) and (H) 1200–700 cm⁻¹. Score plots (A, C, G) showing different days where "blue"—Day 1, "green"—Day 2, "red"—Day 3, "light blue"—Day 4, "violet"—Day 5, "yellow"—Day 6, "black"—Day 7 and (B, D, F) and (H) showing different samples where "blue"—Sample Pi0, "green"—Sample Pi0.5, "red"—Sample Pi0.5, "light blue"—Sample Pi1, "violet"—Sample Pi2, "yellow"—Sample Pi5
