Abashakashatsi bavumbuye imisemburo ibiri mu macandwe y’ibishashara bisanzwe bisenya plastiki isanzwe mu masaha yubushyuhe bwicyumba.
Polyethylene ni imwe muri plastiki zikoreshwa cyane ku isi, zikoreshwa muri byose kuva mu bikoresho birimo ibiryo kugeza mu mifuka yo guhaha.Kubwamahirwe, ubukana bwayo nabwo butuma ihumanya-polymer igomba gutunganywa mubushyuhe bwinshi kugirango itangire inzira yo kwangirika.
Amacandwe ya Waxworm arimo enzyme yonyine izwiho gukora kuri polyethylene idatunganijwe, bigatuma izo poroteyine zisanzwe zishobora kuba ingirakamaro cyane mu gutunganya.
Inzobere mu binyabuzima n’umuvumvu wikunda Federica Bertocchini yavumbuye ku buryo butunguranye ubushobozi bw’inyo zishashara zo kwangiza plastike mu myaka mike ishize.
Bertocchini aherutse kubwira AFP ati: "Igihe kirangiye, abavumvu bakunze kubitsa imitiba mike kugira ngo basubire mu murima mu mpeshyi."
Yasukuye umutiba ashyira inyo zose zishashara mumifuka ya pulasitike.Agarutse nyuma yigihe gito, asanga igikapu "cyatembye".
Waxwings (Galleria mellonella) ni liswi ihinduka inyenzi zimara igihe gito mugihe.Ku cyiciro cya livre, inyo ziba mumitiba, zigaburira ibishashara hamwe nintanga.
Nyuma yubuvumbuzi bushimishije, Bertocchini nitsinda rye mu kigo cy’ubushakashatsi ku binyabuzima Margherita Salas i Madrid batangiye gusesengura amacandwe y’ibishashara maze batangaza ibisubizo byabo mu itumanaho ry’ibidukikije.
Abashakashatsi bakoresheje uburyo bubiri: gel permeation chromatografiya, itandukanya molekile zishingiye ku bunini bwazo, hamwe na gazi chromatografiya-ya misa ya sprometrike, igaragaza ibice bya molekile bishingiye ku kigereranyo cyabyo.
Bemeje ko amacandwe agabanya iminyururu miremire ya hydrocarubone ya polyethylene mo iminyururu mito, okiside.
Abashakashatsi banditse bati:
Abashakashatsi bise imisemburo “Demeter” na “Ceres” bitiriwe imana z'ubuhinzi za kera z'Abagereki n'Abaroma.
Abashakashatsi baranditse bati: "Nkuko tubizi, izi polyvinylase nizo misemburo ya mbere ishoboye gukora ibyo guhindura firime ya polyethylene ku bushyuhe bwicyumba mugihe gito."
Bongeyeho ko kubera ko iyo misemburo yombi itsinze “intambwe ya mbere kandi igoye cyane mu bikorwa byo kwangirika,” inzira ishobora kugereranya “ubundi buryo” bwo gucunga imyanda.
Bertocchini yatangarije AFP ko mu gihe iperereza riri mu ntangiriro, iyo misemburo ishobora kuba yaravanze n'amazi hanyuma igasukwa kuri plastiki ahakorerwa ibicuruzwa.Birashobora gukoreshwa ahantu hitaruye hatagira imyanda cyangwa no murugo.
Ubushakashatsi bwakozwe mu 2021 bwerekana ko mikorobe na bagiteri zo mu nyanja n'ubutaka bigenda bihinduka kugira ngo bigaburire kuri plastiki.
Mu mwaka wa 2016, abashakashatsi bavuze ko bagiteri yabonetse mu myanda yo mu Buyapani isenya terephthalate ya polyethylene (izwi kandi nka PET cyangwa polyester).Nyuma yaje gushishikariza abahanga gukora enzyme ishobora kumena vuba amacupa y’ibinyobwa bya plastiki.
Toni zigera kuri miliyoni 400 z'imyanda ya pulasitike ikorwa buri mwaka ku isi, hafi 30% muri yo ni polyethylene.10% gusa muri toni miliyari 7 z'imyanda ikomoka ku isi imaze gutunganywa kugeza ubu, hasigara imyanda myinshi ku isi.
Kugabanya no gukoresha ibikoresho nta gushidikanya bizagabanya ingaruka z’imyanda ya plastike ku bidukikije, ariko kugira ibikoresho byogusukura ibintu bishobora kudufasha gukemura ikibazo cyimyanda ya plastike.
