“…After 30 days of incubation, the PE particles were collected, washed with 2% sodium dodecyl sulfate, 75% ethanol and 95% ethanol for more than 3 h under ultrasonication, dried overnight in an oven at 60°C, and weighed. The percentage weight loss of the PE particles due to degradation was determined using Equation: Weight loss = (W0 − W)/W0 × 100%, where W0 is the initial weight of the PE particles (g), and W is the residual weight of the PE particles (g) 27 …”

Polyethylene (PE) is a convenient and inexpensive polymer that is widely used in daily life. However, PE products are recalcitrant to degradation in the environment, leading to increasing plastic pollution. This has inspired the search for effective microorganisms and enzymes that can biodegrade PE. In this study, a fungal strain that degrades PE was isolated from soil contaminated with plastic and identified as Trichoderma harzianum. The strain was cultured with PE as the sole carbon source for 30 days, and the weight loss of PE particles was 3.39 ± 0.3%. Scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectra showed holes and oxygenated functional groups on the surface of the degraded PE particles. Gas chromatography–mass spectrometry (GC–MS) detected products with different carbon atom numbers. In addition, a potential PE degrading enzyme was screened from T. harzianum and identified as laccase. After PE was incubated with the recombinant laccase for 96 h, SEM, FTIR, and GC–MS showed the degradation of PE particles. The results showed that T. harzianum had the ability to degrade PE, which probably was attributed to the laccase produced by this strain. This study contributes promising tools for the degradation of PE enzyme.

Polypropylene (PP) is a synthetic, heat-resistant, plastic. This quality has made it the second most commonly used in everyday life, including in disposable medical face masks. While the COVID-19 pandemic has led to an escalation of the face masks use in the last two years, their abundant waste, which is difficult to decompose naturally, can have a negative impact on the environment and human health. The purpose of this study was to obtain isolates of PP decomposing bacteria from the landfill in Ngipik, Gresik. The isolates were obtained from soil samples in the landfill. Bacterial isolates were tested for their ability to degrade PP during the 28 days of the liquid phase. The data obtained were bacterial growth data and PP degradation. There were three isolates that had the potential to decompose PP, namely NG 1, NG 2, and NG 3. It was concluded that the NG2 bacterial isolate is able to decompose PP by 0.47%. Based on the results of 16S sRNA, these three tended to be in the genus of Bacillus. The results of this study are expected to enrich the data of potential local bacteria to decompose PP obtained from Gresik landfill areas.
