Ucwaningo lwe-Microalgae Bio-stimulant With Syngenta China
Muva nje, i-Extracellular Metabolites ye-Heterotrophic Auxenochlorella protothecoides: Umthombo Omusha We-Bio-Stimulants Yezitshalo Eziphakeme ishicilelwe ku-inthanethi kujenali Izidakamizwa Zasolwandle yi-PROTOGA kanye ne-Syngenta China Crop Nutrition Team. Kubonisa ukuthi ukufakwa kwe-microalgae kunwetshwa emkhakheni wezolimo, kucwaningwa amandla ayo ezinto ezivuselela imvelo ezitshalweni eziphakeme. Ukusebenzisana phakathi kwe-PROTOGA nethimba le-Syngenta China Crop nutrition kuhlonze futhi kwaqinisekisa ukuthi kungenzeka yini ama-metabolites angaphandle kwamanzi aphuma emanzini omsila we-microalgae njengomanyolo omusha we-bio, okuthuthukisa ukubaluleka kwezomnotho, ubungane bemvelo kanye nokusimama kwayo yonke inqubo yokukhiqiza ulwelwe oluncane lwezimboni.
▲Umfanekiso 1. I-Graphical abstract
Ukukhiqizwa kwezolimo zanamuhla kuncike kumanyolo wamakhemikhali ngezinga elikhulu, kodwa ukusetshenziswa ngokweqile kukamanyolo wamakhemikhali kubangele ukungcoliswa kwemvelo enhlabathini, emanzini, emoyeni nasekuphepheni kokudla. Ukulima okuluhlaza kuhlanganisa imvelo eluhlaza, ubuchwepheshe obuluhlaza kanye nemikhiqizo eluhlaza, ekhuthaza ukuguqulwa kwezolimo zamakhemikhali zibe ezolimo zemvelo ezithembele kakhulu endleleni yangaphakathi yebhayoloji futhi kunciphisa ukusetshenziswa kukamanyolo wamakhemikhali nezibulala-zinambuzane.
Ama-Microalgae yizinto eziphilayo ezincane ze-photosynthetic ezitholakala emanzini ahlanzekile nezinhlelo zasolwandle ezikwazi ukukhiqiza izinto eziningi ezihlukahlukene ze-bioactive ezifana namaprotheni, ama-lipids, ama-carotenoid, amavithamini, nama-polysaccharides. Kuye kwabikwa ukuthi i-Chlorella Vulgaris, i-Scenedesmus quadricauda, i-Cyanobacteria, i-Chlamydomonas reinhardtii nezinye i-microalgae zingasetshenziswa njenge-Bio-stimulant ye-beet, utamatisi, i-alfalfa neminye imikhiqizo yezolimo esiza ukuthuthukisa ukuhluma kwembewu, ukuqoqwa kwezinto ezisebenzayo nokukhula kwezitshalo.
Ukuze kusetshenziswe kabusha amanzi omsila futhi kwandiswe inani lezomnotho, ngokubambisana ne-Syngenta China Crop Nutrition Team, i-PROTOGA yafunda imiphumela ye-Auxenochlorella protothecoides tail water (EAp) ekukhuleni kwezitshalo eziphakeme. Imiphumela ibonise ukuthi i-EAp ikhuthaze kakhulu ukukhula kwezitshalo eziphakeme ezihlukahlukene kanye nokumelana nokucindezeleka okuthuthukisiwe.
▲Umfanekiso 2. Umphumela we-EAp wezitshalo eziyimodeli
Sihlonze futhi sahlaziya ama-metabolite e-extracellular ku-EAp, futhi sathola ukuthi kunezinhlanganisela ezingaphezu kwe-84, okuhlanganisa ama-organic acid angama-50, ama-phenolic compounds angu-21, ama-oligosaccharides, ama-polysaccharides nezinye izinto ezisebenzayo.
Lolu cwaningo lucabanga ukuthi kungenzeka ukuthi lusebenza kanjani: 1) Ukukhululwa kwama-asidi e-organic kungakhuthaza ukuchithwa kwe-oxide yensimbi enhlabathini, ngaleyo ndlela kuthuthukise ukutholakala kwezakhi zokulandelela ezifana nensimbi, i-zinc nethusi; I-2) Ama-phenolic compounds anemiphumela yokulwa ne-antibacterial noma i-antioxidant, aqinise izindonga zamangqamuzana, avimbele ukulahlekelwa kwamanzi, noma asebenze njengama-molecule abonisa izimpawu, futhi adlale indima ebalulekile ekuhlukaniseni amangqamuzana, ukulawulwa kwe-hormone, umsebenzi we-photosynthetic, i-mineralization yezakhi kanye nokuzala. I-3) I-Microalgae polysaccharides ingakhuphula okuqukethwe kwe-ascorbic acid kanye nemisebenzi ye-NADPH synthase ne-ascorbate peroxidase, ngaleyo ndlela ithinte i-photosynthesis, ukuhlukaniswa kwamaseli kanye nokubekezelelana kokucindezeleka kwe-abiotic kwezitshalo.
