Fig. 7. Fourier-transform infrared (FT-IR) spectroscopy analysis of degraded polystyrene. The plot shows a comparison between untreated and bacterial treated PS samples. Incubation with bacterial strains for 30 days in LCFBM medium at 30 °C leads to the generation of carbonyl group peaks (1632–1644 cm−1) shown with two different PS material – (a) PS pieces (1 × 1 cm), and (b) PS beads. Control indicates PS material incubated and agitated in media without bacteria.
