Ihe ndị dị ụkọ n'ụwa(REEs) dị kalanthanumnaneodymiumbụ akụkụ dị mkpa nke ngwa eletrọnịkị ọgbara ọhụrụ, site na ekwentị na igwe anyanwụ ruo na satịlaịtị na ụgbọ ala eletrik. Ọla ndị a dị arọ na-eme gburugburu anyị, n'agbanyeghị na ọ dị ntakịrị. Ma ọchịchọ na-aga n'ihu na-arị elu na n'ihi na ha na-eme n'ụdị dị nta dị otú ahụ, usoro omenala nke ịwepụta REE nwere ike ghara ịrụ ọrụ nke ọma, na-emetọ gburugburu ebe obibi, na imebi ahụike nke ndị ọrụ.

Ugbu a, na ego sitere na Defence Advanced Research Projects Agency (DARPA) Environmental Microbes dị ka mmemme BioEngineering Resource (EMBER), San Diego State University na-eme nchọpụta na-emepe emepe ụzọ mmịpụta dị elu na ebumnuche nke ịkwalite ọkọnọ ụlọ nke REEs.

"Anyị na-agbalị ịmepụta usoro ọhụrụ maka mgbake nke na-emetụta gburugburu ebe obibi ma na-adịgide adịgide," ka ọkà mmụta ihe ndị dị ndụ na onye isi nchọpụta Marina Kalyuzhnaya kwuru.

Iji mee nke a, ndị na-eme nchọpụta ga-abanye n'ime ọdịdị anụ ahụ nke methane na-eri nje bacteria na-ebi n'ọnọdụ dị oke egwu iji jide REEs site na gburugburu ebe obibi.

"Ha chọrọ ihe ndị na-adịghị ahụkebe nke ụwa iji mee otu n'ime mmeghachi omume enzymatic bụ isi na ụzọ ha metabolic," ka Kalyuzhnaya kwuru.

REE gụnyere ọtụtụ ihe lanthanide nke tebụl oge. Na mmekorita ya na Mahadum California, Berkeley na Pacific Northwest National Laboratory (PNNL), ndị nchọpụta SDSU na-eme atụmatụ ịtụgharị injinia usoro ndu nke na-ekwe ka nje bacteria na-egbute ọla na gburugburu ebe obibi. Ịghọta usoro a ga-eme ka e kee protein ndị na-emepụta sịntetik nke na-ejikọta ya na ụdị lanthanides dị iche iche, dị ka ọkà mmụta biochemist John Love si kwuo. Ndị otu PNNL ga-achọpụta ihe mkpụrụ ndụ ihe nketa nke extremophilic na REE na-akpakọba nje bacteria, wee kọwapụta nnabata REE ha.

Ndị otu ahụ ga-agbanwezi nje bacteria iji mepụta protein ndị na-ejikọta ígwè n'elu sel ha, Love kwuru.

REEs dị nnọọ ukwuu na ọdụ ọdụ m, ihe mkpofu nke ụfọdụ ọla ọla, dị ka aluminom.

"Ọdụ ọdụ m bụ n'ezie ihe efu nke ka nwere ọtụtụ ihe bara uru na ya," Kalyuzhnaya kwuru.

Iji mee ka ọ dị ọcha na ịnakọta REE n'ime, a ga-agbaba mmiri mmiri na nkume ndị a gwepịara egwepịa site na biofilter nwere nje bacteria ndị a gbanwere, na-ekwe ka ndị na-emepụta protein dị n'elu nje bacteria na-ahọrọ na-ejikọta na REEs. Dị ka nje bacteria na-ahụ n'anya nke methane na-eje ozi dị ka ndebiri ha, nje bacteria ndị a na-emeziwanye ga-anabata oke pH, okpomọkụ na salinity, ọnọdụ ndị dị na ọdụ ọdụdụ.

Ndị ọrụ nyocha ahụ ga-ejikọ aka na onye mmekọ ụlọ ọrụ, Palo Alto Research Center (PARC), ụlọ ọrụ Xerox, iji bipụta ihe nwere oghere, sorbent maka ojiji na biofilter. Nkà na ụzụ bioprinting a dị ọnụ ala ma nwee ike ịgbatị ma na-atụ anya na ọ ga-eweta nnukwu ego ma ọ bụrụ na etinyere ya na mgbake ịnweta.

Na mgbakwunye na ịnwale na ịkwalite biofilter, ndị otu a ga-emepụtakwa ụzọ maka ịnakọta lanthanides dị ọcha site na biofilter n'onwe ya, dịka onye injinia gburugburu ebe obibi Christy Dykstra kwuru. Ndị na-eme nchọpụta ejikọtala na ụlọ ọrụ mmalite, Phoenix Tailings, iji nwalee ma mezie usoro mgbake.

N'ihi na ihe mgbaru ọsọ bụ ịmepụta usoro azụmahịa ma ọ bụ gburugburu ebe obibi maka ịwepụta REEs, Dykstra na ọtụtụ ndị mmekọ ọrụ ga-enyocha ụgwọ nke usoro ahụ ma e jiri ya tụnyere teknụzụ ndị ọzọ maka ịweghachi lanthanides, kamakwa mmetụta gburugburu ebe obibi.

Dykstra kwuru, "Anyị na-atụ anya na ọ ga-enweta ọtụtụ uru na gburugburu ebe obibi yana ọnụ ahịa ike dị ala ma e jiri ya tụnyere nke a na-eji ugbu a," Dykstra kwuru. “Sistemụ dị ka nke a ga-abụ nke sistemụ biofiltration na-agafe agafe, yana ntinye ike dị obere. Ma mgbe ahụ, n'ụzọ doro anya, iji obere ihe mgbaze na-emerụ gburugburu ebe obibi na ihe ndị dị otú ahụ. Ọtụtụ usoro dị ugbu a ga-eji ihe mgbaze siri ike na enweghị mmekọrịta gburugburu ebe obibi. "

Dykstra na-ekwukwa na ebe ọ bụ na nje bacteria na-emepụtaghachi onwe ha, nkà na ụzụ ndị na-emepụta ihe na-eme ka ha dị ọhụrụ, "ma ọ bụrụ na anyị na-eji usoro kemịkal eme ihe, anyị ga-anọgide na-emepụta kemịkal na-arịwanye elu."

"Ọ bụrụgodị na ọ ga-eri ntakịrị ntakịrị, ma ọ dịghị emerụ gburugburu ebe obibi, nke ahụ ga-abụ ihe ezi uche dị na ya," Kalyuzhnaya kwuru.

Ebumnuche nke ọrụ DARPA na-akwado bụ inye ihe akaebe nke teknụzụ mgbake nke bio-driven REE-recovery n'ime afọ anọ, nke Kalyuzhnaya kwuru na ọ ga-achọ ọhụụ atụmatụ na echiche ntụgharị uche.

Ọ gbakwụnyere na oru ngo a ga-enye ụmụ akwụkwọ SDSU gụchara akwụkwọ ohere isonye na nyocha multidisciplinary "ma hụ ka echiche nwere ike isi na-eto site n'echiche naanị ruo na ngosipụta pilot."
