Microbial degradation of virgin polyethylene by bacteria isolated from a landfill site

Popis výsledku v původním jazyce

In this study we evaluate the extent of degradation of high-density polyethylene by bacterial isolates obtained from landfill. The microorganisms are isolated from plastic wastes deposited in the landfill for 2-3 years and 17 years. Experiments are conducted under laboratory conditions to degrade virgin high-density polyethylene used in the manufacture of packaging materials. Gravimetric and GC-MS analyses are performed to describe polyethylene decomposition. Of all the bacterial isolates tested, the degradation of polyethylene by Bacillus cereus is the highest, 1.78%, based on weight loss. On the other hand, degradation by Pseudomonas tuomurensis is 0.3%. Degradation products are detected, confirming the progressive degradation of the plastic. The hydrocarbons with single and double bonds are observed most frequently. Our study provides insight into the microbial biodegradation of polyethylene in the environment and contributes to the understanding of the biodegradation processes that may occur in landfills and their progress.
