摘要

In this study, Bacillus cereus (H23B00108), a microbe used for biodegradation of chemically pre-treated PET, was isolated from marine plastic contaminated soil. Degradation was monitored by observing weight loss and changes in physical structure by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and X-ray diffraction patterns (XRD). Over the course of 6 weeks, the Bacillus cereus isolate (H23B00108) may break down PET film by 22 ± 0.15%. Furthermore, there is a lack of biodegradants derived from PET film that may be used as a substrate for the production of compounds with added value. Recovering valuable goods from PET bottles using gas chromatography-mass spectrometry (GC/MS) is the goal of this work, which tries to address this gap. The objective of this study is to fill this need by using gas chromatography-mass spectrometry (GC/MS) to recover valuable products from PET bottles: 5-bis(2-methyl-2-propenyl)-2(5H)-furanone, 3-Methyl-1,4-diazabicyclo[4.3.0]nonan-2,5-dione, 3-(2-Pyrrolidinyl) Propanoic acid, and Dihexylamine.
