Summary

This review summarized the current state of knowledge on bacteria capable of degrading non-biodegradable plastics such as polyethylene, polypropylene, PVC, and PET. The authors identified promising bacterial species and strains reported to attack plastic polymer chains under laboratory conditions. Harnessing plastic-degrading microorganisms is a potential long-term strategy for addressing the mounting global microplastic pollution problem.

In the 21st century, synthetic plastics are a fundamental part of the global economy and the utilization of non-bio-degradable petrochemical plastics such as polyvinyl chloride, polyethylene, polypropylene, polystyrene, and polyethylene terephthalate has increased (80%) worldwide in the last five decades since invention. Conventional petro-chemical plastics either splinter via abiotic factors or segregate and absorb biotic factors during the bio-degradation process however, non-biodegradable petrochemical plastics are resistant to degradation via carrying poisonous excipients. Therefore, the degradation process of non-bio-degradable plastics relies on micro-organisms such as Ideonella sakaiensis 201-F6, Phormidium, Lewinella, Bacillus megaterium, Rhodococcusruber, Serratiamarcescens, Enterobacterasburiae YT1, and Bacillus sp. YP1 as advanced recycling operations only covers approximately 10% of petro-chemical plastic waste. The purpose of this review is to emphasize the source, and mechanism of different micro-organisms capable to decompose petrochemical plastics.
