Gulu lofufuza kuchokera ku Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences (TIB, CAS) lapeza chitukuko chachikulu pakuwonongeka kwa mapulasitiki a polyurethane (PU).
Ukadaulo Wapakati
Gululo linathetsa kapangidwe ka kristalo ka PU depolymerase yakuthengo, ndikupeza momwe mamolekyulu amagwirira ntchito bwino. Pogwiritsa ntchito izi, adapanga "enzyme yopangira" yosinthika kawiri pogwiritsa ntchito ukadaulo wowongolera kusintha kwa ma enzyme. Mphamvu yake yowononga polyurethane yamtundu wa polyester ndi yokwera pafupifupi nthawi 11 kuposa ya enzyme yakuthengo.
Ubwino ndi Mtengo
Poyerekeza ndi njira zachikhalidwe zogwiritsira ntchito kutentha kwambiri komanso kuthamanga kwambiri komanso njira za mankhwala okhala ndi mchere wambiri komanso asidi wambiri, njira yowola zinthu m'thupi imadzitamandira ndi kugwiritsa ntchito mphamvu zochepa komanso kuipitsa pang'ono. Imalolanso kugwiritsa ntchito ma enzyme owonongeka kangapo, zomwe zimapangitsa kuti zikhale zothandiza kwambiri pobwezeretsanso mapulasitiki a PU m'thupi.
