This study aimed to isolate polyethylene-degrading Pseudomonas bacteria and clone the alk-B gene responsible for alkane breakdown, using both direct culture and pre-enrichment methods to identify strains with potential for accelerating biological degradation of high-density plastic waste.

Polymers

Today, high-density plastics such as polyethylene are recognized as one of the major pollutants of the environment by the Global Environment Organization. This study has been designed to isolate bacterial strains of Pseudomonas with polyethylene degradation power and to clone the alk-B gene to be used in the future to expedite the biological degradation of plastic waste. To isolate the polyethylene degrading bacteria, two culture methods were used, direct culture and pre-enriched medium. Bacteri

Preliminary Study On Biodegradation Of Polyethylene By Pseudomonas Aeruginosa

AI summary Read the abstract

Laboratory experiments found that Pseudomonas aeruginosa degraded approximately 6% of LDPE film weight over 30 days in Bushnell Haas medium with LDPE as the sole carbon source, likely through enzymatic mechanisms. The results confirm P. aeruginosa's potential for polyethylene biodegradation as a more sustainable alternative to incineration and landfilling, with further optimization needed for practical application.

Comparative evaluation of polyethylene degradation efficiency by two Pseudomonas aeruginosa strains from urban waste disposal areas

AI summary Read the abstract

Researchers isolated two Pseudomonas aeruginosa bacterial strains from waste disposal sites and found both could use polyethylene as a carbon source, degrading approximately 22–25% of PE mass over 120 days, with chemical analysis confirming structural breakdown of the polymer and identification of degradation intermediates.
