Fungal Biodegradation of Polyvinyl Chloride in Aqueous Environments
AI summary Read the abstract
Fungal consortium (Coriolopsis gallica, Aspergillus niger, Aspergillus flavus) degrades 52.6% of PVC in 60 days
The recalcitrant nature of polyvinyl chloride causes significant environmental challenges during production and disposal. This study aimed to assess the ability of fungi isolated from the washing tank in a plastic production factory to biodegrade polyvinyl chloride (PVC). Over 60 days, fungi isolated were incubated with plastic pieces in Bushnell Haas medium. These strains were identified as Coriolopsis gallica (F1), Aspergillus niger (F2)and Aspergillus flavus (F3). After incubation, three methods were selected: Fourier transform infrared (FTIR) analysis, gas chromatography-mass spectrometry (GC-MS), and weight loss experiments, to determine the biodegradation of PVC. The FTIR analysis demonstrated changing peaks, disappearance, and formation of new bonds of the PVC treated compared with the control. A GC-MS analysis revealed the formation of carboxylic acid, alcohol, nitrile and a new compounds during the decomposition of PVC. The results of the weight loss experiment for microbial strains F1, F2, F3 and fungi consortium (FC) were 19, 25.3, 23.6, and 52.6%, respectively. The FC was prepared by combining all three fungi isolates. The present study concluded that these isolated fungal strains have potential for partial biodegradation of PVC plastics. Nevertheless, the results suggest that fungi consortium plays a significant role in the degradation of PVC in aqueous environment.

AI summary Read the abstract
Researchers isolated fungi from landfill soils and identified strains of Aspergillus and Malassezia species capable of degrading polyvinyl chloride plastic. They optimized conditions for the fungi's depolymerase activity and found that temperature, pH, and metal ion supplements significantly influenced degradation efficiency. The study suggests that these environmental fungi could contribute to eco-friendly approaches for reducing PVC plastic pollution.

This study tested four fungi (Funalia floccosa, Trametes versicolor, Pycnoporus cinnabarinus, and Penicillium oxalicum) for their ability to degrade six common plastics, using ATR-FTIR to track chemical changes. The best results were obtained with F. floccosa after 90-day treatment, degrading approximately 62% of high-density polyethylene, 23.6% of low-density polyethylene, and 35.6% of nylon based on band absorbance changes.
