For ATR-FTIR analysis, all LDPE specimens were taken after 30-day incubation except for blank (fresh film). The colors indicate: blank (fresh LDPE film; cyan); negative control (LDPE specimens incubated in a flask without bacteria; yellow-green); LDPE film samples incubated with B. subtilis (blue) or B. licheniformis (red)Back to article page
