Ithimba locwaningo elivela e-Tianjin Institute of Industrial Biotechnology, i-Chinese Academy of Sciences (TIB, CAS) lifinyelele intuthuko enkulu ekuboleni kwepulasitiki ye-polyurethane (PU).
Ubuchwepheshe Obuyinhloko
Ithimba lixazulule isakhiwo sekristalu se-wild-type PU depolymerase, lembula indlela esebenza ngayo ama-molecule ngemuva kokuwohloka kwayo okusebenzayo. Ngokwakhela kulokhu, bathuthukise i-“enzyme yokwenziwa” ephindwe kabili esebenza kahle besebenzisa ubuchwepheshe bokumba ama-enzyme obuqondiswa ukuziphendukela kwemvelo. Ukusebenza kwayo kokuwohloka kwe-polyurethane yohlobo lwe-polyester cishe kuphakeme ngokuphindwe kayi-11 kunokwe-wild-type enzyme.
Izinzuzo kanye Nenani
Uma kuqhathaniswa nezindlela zendabuko zokushisa okuphezulu kanye nezindlela zamakhemikhali ezinosawoti omningi kanye ne-concentrated-acid, indlela yokubola kwezinto eziphilayo inamandla okusebenzisa amandla amancane kanye nokungcola okuphansi. Iphinde ivumele ukusetshenziswa kabusha kwama-enzyme abhubhisayo izikhathi eziningi, inikeze ithuluzi elisebenza kahle kakhulu lokuphinda kusetshenziswe izinto eziphilayo zepulasitiki ze-PU ngobuningi.
