Comparison of IR band position in the PP films after incubation with Pseudomonas sp. in NB and NA (both control and test).

S. no.	Incubation period	IR band position in NB control-test (cm^−1)	IR band position in NA control-test (cm^−1)	Functional group involved
1	30 days	459.12–458.59	458.78–455.96	C-X stretching
2		1104.03–1102.10	1102.65–1101.96	C-H stretching
3		2722.14–2721.10	2722.18–2721.97	C-H stretching
4		3763.83–3761.66	3763.18–2911.74	O-H stretching
