Biodegradation of a Synthetic Textile Containing PVC by Trametes Versicolor
Disposal of synthetic textile waste by landfill is likely to pose a risk of environmental pollution problems.
Biodegradation remains a viable textile waste management alternative. The objective of this study is to evaluate the
biodegradability of textiles containing polyvinyl chloride (PVC) by acclimated and non-acclimated Trametesversicolor and
to measure the speed of mycelial propagation. A technique of liquid inoculation by mycelial fragments and subsequent
fermentation is used. Mycelium propagation is analyzed over time using photogrammetry with photo analysis being carried
out using ImageJ software. After 21 days, the inoculated samples are significantly absorbed and the fungal biomass
increased. The difference in mass is used to quantify the substrate’s biodegradation. Images of samples inoculated with
previously acclimated fungus to PVC liquid culture show that the fungal strain T. versicolor colonized and metabolically
degraded PVC textile waste thereby causing a loss of weight. The results suggest that previously acclimated fungus is an
attractive alternative for biological treatment of PVC waste.
