Izinto zomhlaba ezingavamile ezivela ku-ore zibalulekile empilweni yanamuhla kepha zibachaze ngemuva kokumbiwa phansi kubiza kakhulu, kulimaza imvelo futhi kwenzeka kakhulu phesheya.

Isifundo esisha sichaza ubufakazi besimiso sokwenza i-bacterium, ama-gluconobact okydans, othatha isinyathelo esikhulu sokuqala esibhekise ekufuneni i-skyrococketing areving asterm action access adanisa ngendlela ehambelana nezindleko zendabuko zendabuko kanye nezindlela zokuhlaziywa futhi ahlanzekile ngokwanele ukufeza amazinga asezemvelo.

"Sizama ukuza nemvelo enobungane, izinga lokushisa eliphansi, lokucindezela okuphansi kokuthola amatshe angenamkhawulo edwaleni," kusho uBuz Bartow, umbhali ophezulu wephepha kanye noprofesa wabasizi beBiological and Envirol Engineering eCornell University.

Izakhi - ezinazo eziyi-15 etafuleni lezikhathi-ziyadingeka ukuze konke kusuka kukhompyutha, omakhalekhukhwini, izikrini, izimoto, izimoto zikagesi nabaqhubi bamabhethri.

Ngenkathi i-US yaphinda yashintsha izinto zayo zomhlaba ezingandile, lowo mkhiqizo wamisa ngaphezu kwamashumi amahlanu eminyaka edlule. Manje, ukucolisiswa kwalezi zinto kwenzeka cishe ngokuphelele kwamanye amazwe, ikakhulukazi iChina.

"Iningi lokukhiqizwa komhlaba okungavamile komhlaba kanye nokukhishwa kusezandleni zamazwe angaphandle," kusho umlobi we-Esteban Gazel, uprofesa wezakhi zomhlaba kanye nesayensi yomkhathi eCornell. "Ngakho-ke ngokuphepha kwezwe lethu nendlela yethu yokuphila, kudingeka sibuyele ekulandeleleni ukulawula leyo nsiza."

Ukuhlangabezana nezidingo zonyaka zonyaka zezinto zomhlaba ezingandile, cishe amathani ayizigidi ezingama-71.5

Izindlela zamanje zincike edwaleni elichithekile nge-Sulfuric Acid, kulandelwa ngokusebenzisa izixazululo ze-organic ukuhlukanisa izinto ezifanayo kakhulu nomunye kusisombululo.

"Sifuna ukuthola indlela yokwenza i-bug eyenza kangcono lowo msebenzi," kusho uBhatistow.

G. Oxydans yaziwa ngokwenza i-acid ebizwa ngokuthi i-biolixiviant ehlakazwa idwala; Amagciwane asebenzisa i-acid ukudonsa ama-phosphase kusuka ezintweni zomhlaba ezingandile. Abacwaningi sebeqalile ukukhohlisa izinhlobo zofuzo ze-G. Oxydans ngakho-ke kukhiphe izinto ngempumelelo.

Ukuze wenze njalo, abacwaningi basebenzise ubuchwepheshe obuthi uBarstow basize ukuthuthuka, okubizwa ngokuthi yiCyonk Sudoku, okwabavumela ukuba bakhubaze izinhlobo zofuzo ezingama-2 783 kuGenome One ngamunye. Iqembu liguquke izinguquko, ngalinye line-gene elithile elikhishwe ngaphandle, ngakho-ke bakwazi ukubona ukuthi yiziphi izinhlobo zofuzo abadlala izindima ekwakheni amadwala.

UGazeli wathi: "Nginethemba elikhulu kakhulu," kusho uGazel. "Sinenqubo lapha ezophumelela kakhulu kunanoma yini eyenziwe ngaphambili."

U-Alexa Schmitz, umcwaningi we-postdoctol eLab's Bartow, nguMlobi wokuqala wesifundo, "i-gluconobacten okydans knowlat iqoqo ithola ukukhishwa okungcono kwe-rare Earth Element," kushicilelwe ekuxhumaneni kwemvelo.
