Itsinda ry'Abashinwa ryavumbuye uburyo bushya bwo gukoresha PU Plastiki zishobora kwangirika, bikongera imikorere myiza inshuro zirenga 10

Itsinda ry’abashakashatsi bo mu Kigo cya Tianjin Institute of Industrial Biotechnology, Ishuri Rikuru ry’Ubumenyi ry’Abashinwa (TIB, CAS) ryageze ku ntambwe ikomeye mu kwangirika kw’ibumba rya polyurethane (PU).

Ikoranabuhanga ry'ibanze

Itsinda ryakemuye imiterere ya kristu ya PU depolymerase yo mu bwoko bwa wild-type, rigaragaza uburyo molekile iri inyuma yo kwangirika kwayo neza. Bashingiye kuri ibi, bakoze "enzyme y'ubukorano" ifite imikorere myiza cyane bakoresheje ikoranabuhanga ryo gucukura enzymes riyobowe n'impinduka. Ubuhanga bwayo bwo kwangirika kuri polyurethane yo mu bwoko bwa polyester buri hejuru y'inshuro 11 ugereranyije n'ubwo mu bwoko bwa wild-type.

Ibyiza n'Agaciro

Ugereranyije n'uburyo gakondo bwo gukoresha ubushyuhe bwinshi n'umuvuduko mwinshi hamwe n'uburyo bwo gukoresha ibinyabutabire birimo umunyu mwinshi n'aside nyinshi, uburyo bwo kwangiza ibidukikije bufite ingufu nke kandi budahumanya ikirere. Butuma kandi enzymes zangirika zishobora kongera gukoreshwa inshuro nyinshi, bigatanga igikoresho cyiza cyo kongera gukoresha PU mu buryo bunini.
