Warqad dhawaan lagu daabacay Joornaalka Kiimikada Bayoloji, cilmi-baarayaasha ETH Zurich waxay sharraxayaan helitaanka lanpepsy, borotiinka si gaar ah ugu xiraya lanthanides - ama curiyeyaasha dhulka naadir - oo ka takoora macdanta iyo biraha kale.

Sababtoo ah waxay la mid yihiin ion birta kale, nadiifinta REE ee deegaanka waa mid dhib badan oo dhaqaale ah oo kaliya meelo yar. Iyagoo taas og, saynis yahannadu waxay go'aansadeen inay sahamiyaan agabka noolaha oo leh sifooyin sare oo ku xidhan lanthanides si ay u noqdaan habab bixin kara dariiq hore loo maro.

Talaabada ugu horeysa waxay ahayd in dib loo eego daraasado hore oo soo jeedinaya in dabeecadda ay soo saartay noocyo kala duwan oo borotiinno ah ama unugyo yaryar si ay u xoqdo lanthanides. Kooxaha kale ee cilmi-baadhistu waxay ogaadeen in bakteeriyada qaarkood, methylotrophs ee beddelaya methane ama methanol, ay leeyihiin enzymes u baahan lanthanides goobahooda firfircoon. Tan iyo markii la helay daahfurka goobtan, aqoonsiga iyo sifada borotiinnada ku lug leh dareenka, qaadashada, iyo ka faa'iidaysiga lanthanides, waxay noqdeen goob cilmi baaris ah oo soo ifbaxaysa.

Si loo aqoonsado jilayaasha cusub ee lanthanome, Jethro Hemmann iyo Philipp Keller oo ay weheliyaan la-hawlgalayaasheeda D-BIOL iyo shaybaarka Detlef Günther ee D-CHAB, waxay daraasad ku sameeyeen jawaabta lanthanide ee methylotroph Methylobacillus flagellatus.

Marka la barbardhigo borotiinka unugyada koray joogitaanka iyo maqnaanshaha lanthanum, waxay heleen borotiinno dhowr ah oo aan hore ula xiriirin isticmaalka lanthanide.

Waxaa ka mid ahaa borotiin yar oo aan la garanayn shaqadiisa, kaas oo kooxdu hadda u bixisay lanpepsy. Sifada in vitro ee borotiinka ayaa shaaca ka qaaday in lagu xidho lanthanides oo leh gaar gaar ah oo sare oo loogu talagalay lanthanum marka loo eego kalsiyum kiimikaad la mid ah.

Lanpepsy waxa ay awood u leedahay in ay ka hodmiso lanthanides ee xalka sidaas awgeedna waxa ay haysaa awoodda horumarinta hababka bioinspired ee nadiifinta joogtada ah ee dhulalka naadir ah.
