TI  - Accelerating the Biodegradation of High-Density Polyethylene (HDPE) Using 
      Bjerkandera adusta TBB-03 and Lignocellulose Substrates.

AB  - High-density polyethylene (HDPE) is a widely used organic polymer and an emerging 
      pollutant, because it is very stable and nonbiodegradable. Several fungal species 
      that produce delignifying enzymes are known to be promising degraders of 
      recalcitrant polymers, but research on the decomposition of plastics is scarce. 
      In this study, white rot fungus, Bjerkandera adusta TBB-03, was isolated and 
      characterized for its ability to degrade HDPE under lignocellulose substrate 
      treatment. Ash (Fraxinus rhynchophylla) wood chips were found to stimulate 
      laccase production (activity was > 210 U/L after 10 days of cultivation), and 
      subsequently used for HDPE degradation assay. After 90 days, cracks formed on the 
      surface of HDPE samples treated with TBB-03 and ash wood chips in both liquid and 
      solid states. Raman analysis showed that the amorphous structure of HDPE was 
      degraded by enzymes produced by TBB-03. Overall, TBB-03 is a promising resource 
      for the biodegradation of HDPE, and this work sheds light on further applications 
      for fungus-based plastic degradation systems.
