Ib pab neeg tshawb fawb los ntawm Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences (TIB, CAS) tau ua tiav qhov kev tshawb pom tseem ceeb hauv kev puas tsuaj ntawm cov yas polyurethane (PU).
Cov Txuj Ci Tseem Ceeb
Cov pab pawg neeg tau daws qhov teeb meem ntawm cov qauv siv lead ua ntawm cov PU depolymerase qus, nrhiav pom cov txheej txheem molecular tom qab nws qhov kev puas tsuaj zoo. Los ntawm qhov no, lawv tau tsim ib qho kev ua haujlwm siab "enzyme dag" ob chav mutant siv cov thev naus laus zis evolution-guided enzyme mining. Nws qhov kev ua haujlwm puas tsuaj rau polyester-hom polyurethane yog ze li ntawm 11 npaug ntau dua li ntawm cov enzyme qus.
Cov Zoo thiab Tus Nqi
Piv nrog rau cov txheej txheem ib txwm muaj uas siv kub thiab siab thiab cov txheej txheem tshuaj lom neeg uas muaj ntsev ntau thiab cov kua qaub ntau, txoj kev ua biodegradation no siv zog tsawg thiab muaj kuab paug tsawg. Nws kuj tseem ua rau siv tau cov enzymes uas ua rau cov khoom puas tsuaj tau ntau zaus, muab cov cuab yeej siv tau zoo dua rau kev siv cov yas PU ua dua tshiab hauv cov tsiaj txhu.
