Biotic Degradation of Plastic Hygiene Products by Using Pleurotus ostreatus

Abstract

Degradation is any physical or chemical adjustment in polymer due to environment factor, such as heat, moisture, light, chemical conditions and biological activity. The aim of this work was to determine the biotic degradation efficiency of plastic hygiene products by using Pleurotus ostreatus. Sanitary pads and diapers were used as samples. All the samples will be exposed to the Pleurotus ostreatus for 90 days. The degradation efficiencies were analysed based on tensile reduction, morphology and chemical properties of the samples by using universal tensile machine, Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR), respectively. The tensile reduction percentage for all samples was increase. The morphology and chemical properties of the samples also showed some changes after undergoes 90 days degradation.

Polyethylene terephthalate (PET) biodegradation by Pleurotus ostreatus and Pleurotus pulmonarius

“…Changes in signal intensity within spectral region 2898 cm − 1 to 3756 cm − 1 (Fig. 2) due to O-H, N-H vibrations and C-H stretching are indicative of the degradative effect of the enzymes secreted by the organism during the experiment (Mismisuraya et al, 2021) because hydrolytic breakdown of the polymer can be traced to various changes in the ν(OH) and ν(CH) bands around 3000 cm-1 (Sammon et al, 2000).…”

“…In addition, P. ostreatus, P. orida, P. pulmonarius, P. eryngii, and some other white-rot fungi, have also been found to break down contaminants like CPs (chlorophenols), gammahexachlorocyclohexane (lindane), etc (Radha et al, 2005). Plastics have been reported to be biodegraded by microorganisms in several studies (Hock et al, 2020, Mismisuraya et al, 2021, Vague et al, 2019, Yoshida et al, 2016. This study aimed to see if Pleurotus ostreatus and Pleurotus pulmonarius fungi can cause the breakdown of PET layers.…”
