Vatsvagiri - vekuPurdue University neYunivhesiti yeWisconsin-Madison vachibatsirana nekutanga Pivot Bio - vakaratidza kuti kushandiswa kwemajene-edited microbes kwaigona sei kupa yakakwana nitrogen yezvirimwa sechibage pamwe nekudzikiswa kwemapaunzi makumi mana ekugadzira nitrogen fetereza panguva. kuwana mwero wakafanana wegoho regoho.
Nhoroondo, anodaro purofesa wesayenzi yezvakatipoteredza paMichigan State University Dr. Bruno Basso, nitrogen management yave yakaoma - nokuti ivhu-plant-atmosphere system yakanyatsopindirana. Uye zvino mafetereza enitrogen anotarisana nematambudziko akati wandei: maitiro ekuchengetedza zvakanakisa muvhu, kusatarisika kwemamiriro ekunze, uye kunyangwe matorerwo ekudya. Iyi tekinoroji nyowani inotsvaga kukurira matambudziko aya uye kuwedzera kugadzirwa uye kuchengetedza kwezvakatipoteredza.
Kubudirira chaiko kuri mukushandiswa kwe“diazotrophs,” mabhakitiriya chaiwo anogona kushandura nitrogen yemumhepo kuita ammonium. Iyi nzira, inozivikanwa sebiological nitrogen fixation (BNF), ndiyo yanga iri hombe yenitrogen kuzvirimwa kusati kwauya mafetireza ekugadzira. Diaotrophs, zvisinei, ane mafomu ekuzvarwa anosanganisira mazhinji e diazotrophs, anoderedza yavo nitrogen-kugadzirisa basa kana yakafumurwa kune yakakwira nitrogen kwenguva yakareba. Vatsvagiri vePivot Bio parizvino vakagadzira gene-edited diazotrophs inoramba ichiita BNF kunyangwe pamazinga enitrogen akakwira, ichikwirisa kuendeswa kwakananga kwenitrogen zvakananga kuzvirimwa.
Mukati metekinoroji iyi, Pivot Bio inopa PROVEN® 40, chigadzirwa chechizvarwa chechipiri chinoshandisa majene-edited microbes kunyatsogadzirisa nitrogen yemuchadenga kunyangwe muvhu rakagadzirwa. Miedzo mumarabhoritari uye muminda yakatsvaga nitrogen yemuchadenga kune chibage shizha chlorophyll uye yakaratidza kuti nitrogen iyi, chokwadi, yaipihwa kubva kumhepo nehutachiona. Ichi chitsva chine chirevo chakadzama sezvo zvidyarwa zviri pasi pePROVEN 40 zvaive nemazinga epamusoro enitrogen pakutanga mumwaka uye aida mashoma ekugadzira fetiraiza.
Muna 2017, Pivot Bio yakawedzera kushandiswa kwezvigadzirwa kweanopfuura mamirioni gumi nematatu maeka muUS mune izvi, zvichiratidza shanduko iri kukura kune zvakatipoteredza zvine hushamwari nitrogen mhinduro. Sekureva kwaDr. Basso, tekinoroji iyi inogona kuderedza kusvibiswa kwekurima zvakanyanya uye nekudaro haibatsiri varimi chete asi nharaunda nekuchengetedza chikafu chepasi rose.
