Abstract: The present invention pertains to a method for producing high value-added compounds from polyethylene terephthalate. More specifically, the present invention demonstrates that a monomeric terephthalic acid obtained from the chemical hydrolysis of polyethylene terephthalate can be converted to high value-added aromatic compounds and aromatic-derived compounds, and ethylene glycol, which is another monomer of polyethylene terephthalate, can be converted to glycolic acid, which is a cosmetic material. The present invention is characterized by recycling polyethylene terephthalate waste into high value-added compounds.

Abstract: The present disclosure pertains to a recombinant Corynebacterium glutamicum strain for production of glutaric acid and a method for production of glutaric acid by using the same. When used to produce glutaric acid, the recombinant Corynebacterium glutamicum strain guarantees an excellent output and allows the selective production of glutaric acid without generation of byproducts, which needs no isolation and purification processes and thus leads to an economical benefit. Consequently, the recombinant strain is useful for production of glutaric acid.
