Iqela lophando elivela kwiTianjin Institute of Industrial Biotechnology, iChinese Academy of Sciences (TIB, CAS) liphumelele kakhulu ekuboleni kwezinto eziphilayo kwiiplastiki zepolyurethane (PU).
Ubuchwepheshe obuphambili
Iqela lisombulule isakhiwo sekristale se-wild-type PU depolymerase, lityhila indlela esebenza ngayo imolekyuli emva kokuwohloka kwayo okusebenzayo. Ngokusebenzisa oku, baphuhlise i-"enzyme yokwenziwa" ephindwe kabini eguquguqukayo besebenzisa iteknoloji yokwemba i-enzyme ekhokelwa yi-evolution. Ukusebenza kwayo kokuwohloka kwe-polyurethane yohlobo lwe-polyester kuphantse kube ngaphezulu ngokuphindwe kalishumi elinanye kune-enzyme yohlobo lwe-wild.
Iingenelo kunye nexabiso
Xa kuthelekiswa neendlela zemveli zobushushu obuphezulu kunye noxinzelelo oluphezulu kunye neendlela zeekhemikhali ezinetyuwa ephezulu kunye ne-concentrated-acid, indlela ye-biodegradation iqhayisa ngokusetyenziswa kwamandla aphantsi kunye nongcoliseko oluphantsi. Ikwavumela ukusetyenziswa kwakhona kwee-enzymes eziwohlokayo amaxesha amaninzi, ibonelela ngesixhobo esisebenzayo ngakumbi sokurisayikilisha okukhulu kwe-PU plastiki kwi-biological.
