PET bottles present to modern society momentous execution qualities wanted by a wide range of shoppers yet the destiny of poly(ethylene terephthalate) in the earth has turned into a huge management problem. For this study, bacteria were isolated from soil-contaminated PET plastic surfaces. The bacteri¬al biofilm formation, bacterial division stages, and single individual colonization of Alcaligenes faecalis (KY026604) bacteria observed by scanning electron microscopy on UV-exposed PET flakes surfaces were compared to UV-untreated PET flakes: UV can provide a starting point for biofilm formation due to their ease of biodegradation. Further, PET degradation was confirmed by FTIR studies, which indicated the for¬mation of a new functional group (C=O bond stretching, C-C bond stretching, C-H bond stretching, C-H bond stretching, C-H bond stretching, C-C-O bond stretching) as evinced in day UV exposed PET.
