Ndị ọkà mmụta sayensị sitere n'ike mmụọ nsọ Pac-Man wee mepụta "mmanya" na-eri plastik, nke nwere ike inye aka wepu mkpofu plastik.
Ọ nwere enzymes abụọ-PETase na MHETase nke nje bacteria a na-akpọ Ideonella sakaiensis nke na-eri na karama plastik.
N'adịghị ka mbibi nke okike, nke na-ewe ọtụtụ narị afọ, nnukwu enzyme a nwere ike ịgbanwe plastik n'ime "mmiri" mbụ ya n'ime ụbọchị ole na ole.
Enzym abụọ a na - arụkọ ọrụ ọnụ, dị ka "Pac-Man abụọ ejikọtara site na eriri" na - ata bọọlụ.
Enzyzy ọhụrụ a na-agbaze plastik ugboro isii karịa ngwa mbụ PETase enzyme achọpụtara na 2018.
Ebumnuche ya bụ polyethylene terephthalate (PET), thermoplastic kachasị arụ ọrụ iji mee karama mmanya, uwe, na kapeeti, nke na-ewekarị ọtụtụ narị afọ iji ree na gburugburu ebe obibi.
Prọfesọ John McGeehan nke Mahadum Portsmouth gwara ụlọ ọrụ mgbasa ozi PA na ugbu a, anyị na-enweta ihe ndị a dị mkpa site na mmanụ ala dị ka mmanụ na gas. Nke a bụ n'ezie enweghị nkwado.
"Ma ọ bụrụ na anyị nwere ike itinye enzymes na-emebi plastik, anyị nwere ike imebi ya n'ime ụbọchị ole na ole."
Na 2018, Prọfesọ McGeehan na ndị otu ya sụrụ ngọngọ na ụdị enzyme a na-akpọ PETase nke nwere ike imebi plastik n'ime ụbọchị ole na ole.
N'ime ihe omumu ohuru ha, ndi oru nyocha a gwakọtara PETase na enzyme ozo a na-akpo MHETase ma choputa na "mgbaze nke karama plastik abiala okpukpu abuo."
Mgbe ahụ, ndị na-eme nchọpụta jiri usoro mkpụrụ ndụ ihe nketa jikọta enzymes abụọ a ọnụ na ụlọ nyocha, dịka "ijikọ Pac-Man abụọ na eriri."
"PETase ga-emebi elu plastik ahụ, MHETase ga-egbutu ọzọ, yabụ lee ma anyị nwere ike iji ha ọnụ iji imitateomie ọnọdụ dị n'okike, ọ dị ka ihe okike." Prọfesọ McGeehan kwuru.
"Nnwale mbụ anyị gosipụtara na ha na-arụkọ ọrụ ọnụ karịa, yabụ anyị kpebiri ịnwa ijikọ ha."
"Obi dị anyị ezigbo ụtọ ịhụ na enzyme ọhụrụ chimeric anyị ji okpukpu atọ karịa nke enzyme a na-ekewapụ iche, nke na-emepe ụzọ ọhụụ maka mmụba ndị ọzọ."
Prọfesọ McGeehan jikwa Diamond Light Source, synchrotron dị na Oxfordshire. Ọ na-eji X-ray dị ike ugboro 10 karịa ìhè karịa anyanwụ dị ka microscope, nke siri ike iji hụ atom n'otu n'otu.
Nke a nyere ndị otu nyocha ahụ aka ịchọpụta ụzọ akụkụ atọ nke MHETase enzyme ma nye ha usoro ihe omimi iji malite ịhazi usoro enzyme ngwa ngwa.
Na mgbakwunye na PET, a pụkwara iji enzyme a dị elu maka PEF (polyethylene furanate), bioplastic dabeere na shuga na-eji karama biya, ọ bụ ezie na ọ pụghị ịkụda ụdị plastik ndị ọzọ.
Ndị otu a na - achọ ụzọ iji mee ka usoro ire ere ngwa ngwa ka e wee nwee ike iji teknụzụ maka ebumnuche azụmahịa.
Prọfesọ McGeehan kwuru, sị, "Ngwa ngwa anyị na-eme enzymes, anyị na-eme ngwa ngwa plastik, yana ọnụọgụ azụmahịa ya dị elu."
