Masana kimiyya sun kirkiro enzyme wanda zai iya kara saurin bazuwar filastik sau shida. Anyi amfani da enzyme da aka samu a cikin kwayoyin cuta na kwandon shara wanda ke cin abincin kwalban roba tare da PETase don hanzarta bazuwar filastik.
Sau uku ayyukan super enzyme
Designedungiyar ta tsara enzyme na PETase na halitta a cikin dakin gwaje-gwaje, wanda zai iya hanzarta bazuwar PET da kusan 20%. Yanzu, wannan ƙungiyar ta transatlantic ta haɗu da PETase da "abokin tarayya" (enzyme na biyu da ake kira MHETase) don samar da ci gaba ma mafi girma: kawai haɗuwa da PETase tare da MHETase na iya ƙara saurin bazuwar PET Sau biyu, kuma tsara haɗin tsakanin enzymes biyu don ƙirƙirar "super enzyme" wanda ke ninka wannan aikin.
Tawagar na karkashin jagorancin masanin kimiyyar da ya tsara PETase, Farfesa John McGeehan, darektan Cibiyar Innovation Inzyvation (CEI) a Jami'ar Portsmouth, da Dokta Gregg Beckham, wani babban mai bincike a National Labour Energy Energy Laboratory (NREL). A cikin Amurka
Farfesa McKeehan ya ce: Ni da Greg muna magana ne game da yadda PETase ke lalata saman robobi, kuma MHETase ya kara ragargaza shi, saboda haka dabi'a ne mu ga ko za mu iya amfani da su tare don kwaikwayon abin da ke faruwa a yanayi. "
Enzymes biyu suna aiki tare
Gwaje-gwajen farko sun nuna cewa wadannan enzymes na iya yin aiki tare sosai, don haka masu binciken suka yanke shawarar kokarin hada su da jiki, kamar hada Pac-Man biyu da igiya.
"An yi ayyuka da yawa a bangarorin biyu na tekun Atlantika, amma ya dace da kokarin - muna farin cikin ganin cewa sabon enzyme dinmu ya ninka saurin enzyme na halitta sau uku cikin sauri, yana bude sabbin hanyoyi don ci gaba da ci gaba. " McGeehan ya ci gaba.
Dukansu PETase da sabon haɗin MHETase-PETase na iya aiki ta narke filastik ɗin PET da dawo da shi zuwa asalin sa. Ta wannan hanyar, ana iya kerar robobi da sake amfani da su har abada, ta haka za mu rage dogaro da albarkatun ƙasa kamar mai da gas.
Farfesa McKeehan ya yi amfani da wani sinadarin ne a cikin Oxfordshire, wanda ke amfani da hasken rana, wadanda suka ninka rana karfi sau biliyan 10, a matsayin madubin hangen nesa, wanda ya isa ya lura da kwayoyin halittar mutum. Wannan ya ba wa ƙungiyar bincike damar warware tsarin 3D na MHETase enzyme, don haka samar musu da tsarin tsarin kwayoyin don fara tsara tsarin enzyme da sauri.
Wannan sabon binciken ya haɗu da tsarin tsari, lissafi, kimiyyar halittu da hanyoyin kere kere don bayyana fahimtar kwayar halitta game da tsarinta da aikin ta. Wannan binciken babban yunƙurin ƙungiya ne wanda ya shafi masana kimiyya na duk matakan aiki.
