Uphando lweMicroalgae Bio-stimulant kunye neSyngenta China

Kungekudala, i-Metabolites ye-Extracellular ye-Heterotrophic Auxenochlorella protothecoides: Umthombo omtsha we-Bio-Stimulants kwiZityalo eziPhakamileyo zapapashwa kwi-intanethi kwi-intanethi ye-Marine Drugs yi-PROTOGA kunye ne-Syngenta China Crop Nutrition Team. Ibonisa ukuba ukufakwa kwe-microalgae kwandiswe kwintsimi yezolimo, kuphononongwa amandla ayo ezinto ezivuselela indalo kwizityalo eziphezulu. Intsebenziswano phakathi kwe-PROTOGA kunye ne-Syngenta China Iqela lesondlo sezityalo liye lachonga kwaye laqinisekisa ukuba nokwenzeka kwee-metabolites ze-extracellular kumanzi omsila we-microalgae njenge-bio-fertilizer entsha, ephucula ixabiso lezoqoqosho, ubuhlobo bendalo kunye nokuzinza kwayo yonke inkqubo yokuvelisa i-microalgae yezoshishino.

▲Umzobo 1. I-Graphical abstract

Imveliso yezolimo yanamhlanje ixhomekeke kwisichumiso sekhemikhali kakhulu, kodwa ukusetyenziswa ngokugqithisileyo kwesichumisi sekhemikhali kubangele ungcoliseko lokusingqongileyo emhlabeni, emanzini, emoyeni nakukhuseleko lokutya . Ulimo oluhlaza lubandakanya indalo eluhlaza, iteknoloji eluhlaza kunye neemveliso eziluhlaza, ezikhuthaza ukuguqulwa kwezolimo zemichiza kulimo lwendalo oluxhomekeke kwi-biological mechanism yangaphakathi kunye nokunciphisa ukusetyenziswa kwezichumisi zekhemikhali kunye nezibulala-zinambuzane.

I-Microalgae zizidalwa ezincinci ze-photosynthetic ezifumaneka kumanzi acocekileyo kunye neenkqubo zaselwandle ezikwazi ukuvelisa izinto ezininzi ezahlukeneyo ze-bioactive ezifana neeprotheni, i-lipids, i-carotenoids, iivithamini kunye ne-polysaccharides. Kuye kwaxelwa ukuba iChlorella Vulgaris, iScenedesmus quadricauda, ​​iCyanobacteria, iChlamydomonas reinhardtii kunye nezinye i-microalgae zingasetyenziswa njenge-Bio-stimulant ye-beet, i-tomato, i-alfalfa kunye nezinye iimveliso zezolimo ezinceda ukuphucula imbewu, ukuqokelela izinto ezisebenzayo kunye nokukhula kwezityalo.

Ukuze kusetyenziswe kwakhona amanzi omsila kunye nokwandisa ixabiso lezoqoqosho, ngokubambisana ne-Syngenta China Crop Nutrition Team, i-PROTOGA yafunda imiphumo ye-Auxenochlorella protothecoides amanzi omsila (EAP) ekukhuleni kwezityalo eziphezulu. Iziphumo zibonise ukuba i-EAp ikhuthaze kakhulu ukukhula kwezityalo ezahlukeneyo eziphezulu kunye nokuphucula ukuxhathisa uxinzelelo.

▲Umfanekiso 2. Impembelelo yeEAp kwimodeli yezityalo

Sichonge kwaye sihlalutye i-metabolites ye-extracellular kwi-EAp, kwaye safumanisa ukuba kukho ngaphezu kwe-84 i-compounds, kuquka i-50 ye-organic acids, i-21 phenolic compounds, i-oligosaccharides, i-polysaccharides kunye nezinye izinto ezisebenzayo.

Olu pho nonongo lubonisa indlela enokwenzeka ngayo yokusebenza: 1) Ukukhutshwa kwe-acids ye-organic kunokukhuthaza ukuchithwa kwee-oxide zetsimbi emhlabeni, ngaloo ndlela kuphuculwe ukufumaneka kwezinto zokulandelela ezifana nentsimbi, i-zinc kunye nobhedu; I-2) Iingqungquthela ze-Phenolic zineempembelelo ze-antibacterial okanye i-antioxidant, zomeleza iindonga zeseli, zikhusela ukulahleka kwamanzi, okanye zisebenze njengeemolekyuli zokubonisa, kwaye zidlala indima ephambili kwi-cell division, ukulawulwa kwe-hormone, umsebenzi we-photosynthetic, i-mineralization yezondlo kunye nokuzala. I-3) I-Microalgae polysaccharides inokunyusa umxholo we-ascorbic acid kunye nemisebenzi ye-NADPH synthase kunye ne-ascorbate peroxidase, ngaloo ndlela ichaphazela i-photosynthesis, i-cell division kunye ne-abiotic stress tolerance of plant.
