Ibintu bidakunze kubaho mu bucukuzi bw'amabuye y'agaciro ni ingenzi mu buzima bwa none ariko kubitunganya nyuma yo gucukura birahenze, byangiza ibidukikije kandi ahanini bibera mu mahanga.

Ubushakashatsi bushya busobanura igihamya cyamahame ya injeniyeri ya bagiteri, Gluconobacter oxydans, ifata intambwe yambere yambere iganisha ku kuzamuka kwikirere kidasanzwe ku isi mu buryo bujyanye nigiciro nuburyo bukoreshwa muburyo bwo kuvoma amashyanyarazi hamwe nuburyo bunonosoye kandi bifite isuku ihagije bujuje ibipimo by’ibidukikije muri Amerika.

Buz Barstow, umwanditsi mukuru w'iki kinyamakuru akaba n'umwarimu wungirije ushinzwe ibinyabuzima n'ibidukikije muri Kaminuza ya Cornell.

Ibintu-muri byo harimo 15 mumeza yigihe-birakenewe mubintu byose uhereye kuri mudasobwa, terefone ngendanwa, ecran, mikoro, turbine yumuyaga, ibinyabiziga byamashanyarazi hamwe na kanseri kugeza kuri radar, sonar, amatara ya LED na bateri zishishwa.

Mu gihe Amerika yigeze gutunganya ibintu byayo bidasanzwe ku isi, umusaruro wahagaze mu myaka irenga mirongo itanu ishize.Noneho, gutunganya ibyo bintu bibera hafi mubindi bihugu, cyane cyane Ubushinwa.

Umwanditsi wungirije witwa Esteban Gazel, umwarimu wungirije w’ubumenyi bw’ikirere n’ubumenyi bw’ikirere muri Cornell yagize ati: "Umubare munini w’ibicuruzwa bidasanzwe byo ku isi no kubikuramo biri mu maboko y’amahanga.""Kugira ngo umutekano w'igihugu cyacu n'imibereho yacu, dukeneye gusubira mu nzira yo kugenzura uwo mutungo."

Kugira ngo Amerika ikenure buri mwaka ibintu bidasanzwe ku isi, hafi toni miliyoni 71.5 (~ toni miliyoni 78.8) z’amabuye y'agaciro byasabwa gukuramo ibiro 10,000 (~ 22.000 pound) by'ibintu.

Uburyo bugezweho bushingira ku gushonga urutare hamwe na acide sulfurike ishyushye, hagakurikiraho gukoresha ibishishwa kama kugirango bitandukane ibintu bisa nkibindi mubisubizo.

Barstow ati: "Turashaka kumenya uburyo bwo gukora amakosa akora ako kazi neza".

G. oxydans izwiho gukora aside yitwa biolixiviant ishonga urutare;bagiteri ikoresha aside kugirango ikure fosifeti mubintu bidasanzwe byisi.Abashakashatsi batangiye gukoresha ingirabuzimafatizo za G. oxydans bityo ikuramo ibintu neza.

Kugira ngo babigereho, abashakashatsi bifashishije ikoranabuhanga Barstow yafashaga kwiteza imbere, ryitwa Knockout Sudoku, ryabemerera guhagarika ingirabuzima fatizo 2.733 ziri muri genome ya G. oxydans umwe umwe.Itsinda ryakosoye mutant, buriwese ufite gene yihariye yakuweho, kugirango bashobore kumenya genes zigira uruhare mukuvana ibintu mubutare.

Gazel ati: "Mfite ibyiringiro bidasanzwe.""Dufite inzira hano igiye gukora neza kuruta icyakozwe mbere."

Alexa Schmitz, umushakashatsi w’iposita muri laboratoire ya Barstow, ni we mwanditsi wa mbere w’ubwo bushakashatsi, "Icyegeranyo cya Gluconobacter oxydans Knockout gisanga uburyo bwiza bwo gukuramo isi budasanzwe," bwasohotse mu itumanaho ry’ibidukikije.
