Ofufuza - ochokera ku yunivesite ya Purdue ndi yunivesite ya Wisconsin-Madison mogwirizana ndi oyambitsa Pivot Bio - adawonetsa momwe kugwiritsa ntchito tizilombo toyambitsa matenda kungaperekedwe kokwanira kwa nayitrogeni ku mbewu monga chimanga ndikuchepetsa mwina mapaundi 40 akugwiritsa ntchito feteleza wa nayitrogeni. kukwaniritsa mlingo wofanana wa zokolola.
Zakale, akutero pulofesa wa sayansi ya zachilengedwe ku Michigan State University Dr. Bruno Basso, kasamalidwe ka nayitrogeni kwakhala kovuta - chifukwa dongosolo la nthaka-chomera-mlengalenga limagwirizana kwambiri. Ndipo tsopano feteleza wa nayitrogeni amakumana ndi zovuta zingapo: momwe angasungire bwino m'nthaka, kusadziwikiratu kwanyengo, komanso momwe zakudya zimatengera. Tekinoloje yatsopanoyi ikufuna kuthana ndi mavutowa ndikuwonjezera zokolola komanso kukhazikika kwa chilengedwe.
Kupambana kwenikweni kwagona kugwiritsa ntchito “diazotrophs,” mabakiteriya apadera omwe mwachibadwa amatha kusintha nayitrogeni wa mumlengalenga kukhala ammonium. Njira imeneyi, yotchedwa biological nitrogen fixation (BNF), inali gwero lalikulu la nayitrogeni ku mbewu kusanabwere feteleza wopangira. Ma Diaotrophs, omwe mitundu yawo yachilengedwe imakhala ndi ma diazotrophs ambiri, amachepetsa ntchito yawo yokonza nayitrogeni ngati akumana ndi nayitrogeni wambiri kwa nthawi yayitali. Ofufuza a Pivot Bio tsopano apanga ma diazotrophs osinthidwa ndi jini omwe akupitilizabe kuchita BNF ngakhale pamlingo wapamwamba wa nayitrogeni, kukulitsa kuperekedwa kwa nayitrogeni mwachindunji ku mbewu.
Pakatikati pa ukadaulo uwu, Pivot Bio imapereka PROVEN® 40, chinthu cham'badwo wachiwiri chogwiritsa ntchito majeremusi osinthidwa ndi majini kukonza bwino nayitrogeni wa mumlengalenga ngakhale mu dothi lopangidwa ndi feteleza. Mayesero onse m'ma lab ndi m'minda adatsata nayitrogeni wam'mlengalenga kupita ku masamba a chimanga a chlorophyll ndipo adatsimikizira kuti nayitrogeniyu amaperekedwa kuchokera mumlengalenga ndi tizilombo tating'onoting'ono. Zatsopanozi zili ndi tanthauzo lozama chifukwa mbewu zomwe zili pansi pa PROVEN 40 zinali ndi nayitrogeni wochulukirapo m'nyengoyi ndipo zimafunikira feteleza wopangidwa pang'ono.
Mu 2017, Pivot Bio adakulitsa kugwiritsidwa ntchito kwa zinthu kwa maekala opitilira 13 miliyoni ku US motere, kuwonetsa kusintha komwe kukukulirakulira kwa njira zothanirana ndi chilengedwe. Malinga ndi Dr. Basso, ukadaulo uwu ukhoza kuchepetsa kuwonongeka kwaulimi ndipo motero umathandiza osati alimi okha komanso zachilengedwe komanso chitetezo cha chakudya padziko lonse lapansi.
