Abaphandi-abasuka kwiDyunivesithi yasePurdue kunye neDyunivesithi yaseWisconsin-Madison ngentsebenziswano nePivot Bio eqalayo- babonise indlela ukusetyenziswa kwee-microbes ezihlelwe ngofuzo kunokubonelela ngobonelelo lwenitrogen olwaneleyo lwezityalo ezinjengombona ngokuncipha okunokwenzeka kweeponti ezingama-40 zokusetyenziswa kwesichumiso senitrogen ngelixa. ukufikelela kwinqanaba elifanayo lesivuno sesityalo.
Ngokomlando, uthi uprofesa wesayensi yendalo kwiYunivesithi yaseMichigan State uDkt. Bruno Basso, ulawulo lwe-nitrogen luye lwaba nzima - kuba inkqubo yomhlaba-yesityalo-i-atmosphere inxulumene kakhulu. Kwaye ngoku izichumisi zenitrogen zijongene nemingeni emininzi: indlela yokugcina umhlaba, ukungaqiniseki kwemozulu, kunye nokuba izondlo zifunxwa njani. Le teknoloji intsha ifuna ukoyisa ezi ngxaki kwaye yandise imveliso kunye nokuzinza kokusingqongileyo.
Impumelelo yokwenyani isekusetyenzisweni kwee-“diazotrophs,” iibhaktiriya ezikhethekileyo ezinokuguqula ngokwendalo initrogen esemoyeni ibe yiammonium. Le nkqubo, eyaziwa ngokuba yi-biological nitrogen fixation (BNF), ibiyeyona nto ingumthombo wenitrogen kwizityalo ngaphambi kokufika kwezichumisi zokwenziwa. I-diaotrophs, nangona kunjalo, iifom zazo zendalo ziquka uninzi lwe-diazotrophs, zinciphisa umsebenzi wazo wokulungisa i-nitrogen ukuba zibonakaliswe kumazinga aphezulu e-nitrogen ixesha elide. Abaphandi bePivot Bio baye benza ngoku ii-diazotrophs ezihlelwe ngofuzo eziqhubeka nokwenza i-BNF nakumanqanaba aphezulu e-nitrogen, ukwandisa ukuhanjiswa ngokuthe ngqo kwe-nitrogen ngqo kwizityalo.
Embindini wale teknoloji, i-Pivot Bio inikezela iPROVEN® 40, imveliso yesizukulwana sesibini esebenzisa i-microbes ehlelwe ngofuzo ukulungisa ngokufanelekileyo i-nitrogen ye-atmospheric nakwimihlaba echunyiswe ngokwenziwa. Iimvavanyo zombini kwiilebhu kunye nezicwangciso zentsimi zilandelelanisa i-nitrogen ye-atmospheric ukuya kwi-corn leaf chlorophyll kwaye yangqina ukuba le nitrogen, ngokwenene, ibonelelwe ukusuka emoyeni yi-microbes. Olu tshintsho lunentsingiselo enzulu njengoko izityalo eziphantsi kwe-PROVEN 40 zinemigangatho ephezulu yenitrogen ekuqaleni kwixesha lonyaka kwaye zidinga isichumiso esincinci sokwenziwa.
Ngo-2017, i-Pivot Bio yandisa ukusetyenziswa kweemveliso ngaphezu kwe-13 yezigidi zeehektare e-US kulo mba, ebonisa utshintsho olukhulayo kwizisombululo ze-nitrogen ezihambelana nokusingqongileyo. Ngokutsho kukaGqr. Basso, obu bugcisa bunokunciphisa kakhulu ungcoliseko lwezolimo kwaye ngoko ke aluncedi kuphela amafama kodwa i-ecosystem kunye nokhuseleko lokutya lwehlabathi.
