Uphando lweMicroalgae Bio-stimulant kunye neSyngenta China

Kutshanje, i-Extracellular Metabolites ye-Heterotrophic Auxenochlorella protothecoides: Umthombo Omtsha we-Bio-Stimulants for Higher Plants ipapashwe kwi-intanethi kwijenali yeMarine Drugs yi-PROTOGA kunye ne-Syngenta China Crop Nutrition Team. Ibonisa ukuba ukusetyenziswa kwe-microalgae kwandiswa ukuya kwintsimi yezolimo, kuhlolwa amandla ayo e-bio-stimulants kwizityalo eziphezulu. Intsebenziswano phakathi kwe-PROTOGA kunye neqela lesondlo se-Syngenta China Crop ichonge kwaye yaqinisekisa ukuba kunokwenzeka i-metabolites engaphandle kwamanzi avela kumsila we-microalgae njenge-bio-fertilizer entsha, iphucula ixabiso lezoqoqosho, ubuhlobo bokusingqongileyo kunye nokuzinza kwenkqubo yonke yokuvelisa i-microalgae kwimizi-mveliso.

▲Umfanekiso 1. Isishwankathelo semizobo

Imveliso yezolimo yanamhlanje ixhomekeke kakhulu kwisichumiso seekhemikhali, kodwa ukusetyenziswa kakhulu kwesichumiso seekhemikhali kubangele ungcoliseko lokusingqongileyo kumhlaba, emanzini, emoyeni nakukhuseleko lokutya. Ulimo oluluhlaza lubandakanya okusingqongileyo okuluhlaza, iteknoloji eluhlaza kunye neemveliso eziluhlaza, ezikhuthaza ukuguqulwa kwezolimo lweekhemikhali ukuya kwezolimo oluhlala luxhomekeke kakhulu kwindlela yangaphakathi yebhayoloji kwaye kunciphisa ukusetyenziswa kwezichumiso zeekhemikhali kunye nezibulali zinambuzane.

IiMicroalgae zizinto eziphilayo ezincinci ezifumaneka kwiindawo zamanzi acocekileyo kunye neenkqubo zaselwandle ezikwaziyo ukuvelisa izinto ezininzi ezahlukeneyo eziphilayo ezifana neeproteni, ii-lipids, ii-carotenoids, iivithamini, kunye nee-polysaccharides. Kuye kwaxelwa ukuba iChlorella Vulgaris, iScenedesmus quadricauda, ​​iCyanobacteria, iChlamydomonas reinhardtii kunye nezinye ii-microalgae zingasetyenziswa njengeBio-stimulant kwi-beet, iitumato, i-alfalfa kunye nezinye iimveliso zezolimo ezinceda ukuphucula ukuhluma kwembewu, ukuqokelelana kwezinto ezisebenzayo kunye nokukhula kwezityalo.

Ukuze kusetyenziswe kwakhona amanzi asemva kwesityalo kunye nokunyusa ixabiso lezoqoqosho, ngokubambisana neSyngenta China Crop Nutrition Team, iPROTOGA ifunde ngemiphumo yeAuxenochlorella protothecoides tail water (EAp) ekukhuleni kwezityalo eziphezulu. Iziphumo zibonise ukuba i-EAp ikhuthaze kakhulu ukukhula kwezityalo ezahlukeneyo eziphakamileyo kwaye iphucule ukumelana noxinzelelo.

▲Umfanekiso 2. Impembelelo ye-EAp ye-EAp kwizityalo zemodeli

Sichonge saza sahlalutya ii-metabolites ezingaphandle kweseli kwi-EAp, saza safumanisa ukuba kukho iikhompawundi ezingaphezu kwama-84, kuquka ii-asidi ze-organic ezingama-50, iikhompawundi ze-phenolic ezingama-21, ii-oligosaccharides, ii-polysaccharides kunye nezinye izinto ezisebenzayo.

Olu phononongo lucinga ukuba indlela esebenza ngayo: 1) Ukukhululwa kwee-organic acids kunokukhuthaza ukunyibilika kwee-metal oxides emhlabeni, ngaloo ndlela kuphuculwe ukufumaneka kwezinto ezilandelelanayo ezifana nentsimbi, i-zinc kunye ne-copper; 2) Ii-phenolic compounds zinefuthe lokulwa neentsholongwane okanye i-antioxidant, zomeleza iindonga zeeseli, zithintele ukulahleka kwamanzi, okanye zisebenza njengee-molecules zokubonisa, kwaye zidlala indima ephambili ekwahlulweni kweeseli, ukulawulwa kweehomoni, umsebenzi we-photosynthetic, ukwenziwa kweminerali kwezondlo kunye nokuzala. 3) Ii-microalgae polysaccharides zinokunyusa umxholo we-ascorbic acid kunye nemisebenzi ye-NADPH synthase kunye ne-ascorbate peroxidase, ngaloo ndlela zichaphazela i-photosynthesis, ukwahlulwa kweeseli kunye nokunyamezela uxinzelelo lwezityalo.
