Microbial degradation of polyethylene terephthalate: a systematic review

چکیده
Abstract Plastic pollution levels have increased rapidly in recent years, due to the accumulation of plastic waste, including polyethylene terephthalate (PET). Both high production and lack efficient methods for disposal recycling affect diverse aquatic terrestrial ecosystems owing rates plastics. Traditional chemical physical degradation techniques caused adverse effects on environment; hence, use microorganisms has gained importance recently. This systematic review was conducted evaluating reported findings about PET by wild genetically modified make them available future work contribute eventual implementation an alternative, effective, environmentally friendly method management waste such as PET. with metabolic potential degrade this polymer were identified, addition enzymes genes used genetic modification. The most prevalent wild-type PET-degrading bacteria (56.3%, 36 genera), followed fungi (32.4%, 30 microalgae (1.4%; 1 genus, namely Spirulina sp.), invertebrate associated microbiota (2.8%). Among bacteria, genera Aspergillus sp. Bacillus sp . , respectively. About microorganisms, 50 strains Escherichia coli expressing PETase enzyme, been used. We emphasize pressing need implementing biological a commercial scale, using consortia microorganisms. present five sections: Introduction that highlights biodegradation effective sustainable section Materials summarizes how search articles manuscripts different databases done, another Results where we works found subject, final part Discussion analysis literature finally Conclusion prospects.

Microbial degradation of polyethylene glycols.
Mono-, di-, tri-, and tetraethylene glycols and polyethylene glycols (PEG) with molecular weight up to 20,000 were degraded by soil microorganisms. A strain of Pseudomonas aeruginosa able to use a PEG of average molecular weight 20,000 was isolated from soil. Washed cells oxidized mono- and tetraethylene glycols, but O2 consumption was not detectable when such cells were incubated for short per...
متن کاملImmobilization of silver nanoparticles on polyethylene terephthalate
Two different procedures of grafting with silver nanoparticles (AgNP) of polyethylene terephthalate (PET), activated by plasma treatment, are studied. In the first procedure, the PET foil was grafted with biphenyl-4,4'-dithiol and subsequently with silver nanoparticles. In the second one, the PET foil was grafted with silver nanoparticles previously coated with the same dithiol. X-ray photoelec...
متن کاملMicrobial Degradation of Plastic- a Brief Review
Synthetic polymers are widely used both in food or commercial industry. Plastic, one of its products is known to be expanding with changing lifestyles and increasing population. However, it causes deleterious effects on the environment due to its non degrading nature. Burning of this plastic waste and burying of the plastics releases harmful toxic material which is a major pollutant in environm...
متن کاملConfinement-induced vitrification in polyethylene terephthalate
Dynamic mechanical thermal analysis performed on cold-drawn polyethylene terephthalate PET , cold crystallized annealed in the temperature interval 100–140 °C, reveals the presence of marginally glassy domains above the annealing temperature Ta. This suggests that the thermodynamic force driving crystallization causes the structural arrest of some noncrystalline domains. The latter thus need a ...
متن کاملPolyethylene Terephthalate May Yield Endocrine Disruptors
BACKGROUND Recent reports suggest that endocrine disruptors may leach into the contents of bottles made from polyethylene terephthalate (PET). PET is the main ingredient in most clear plastic containers used for beverages and condiments worldwide and has previously been generally assumed not to be a source of endocrine disruptors. OBJECTIVE I begin by considering evidence that bottles made fr...
