Kafukufuku wa Microalgae Bio-stimulant ndi Syngenta China

Posachedwapa, Extracellular Metabolites of Heterotrophic Auxenochlorella protothecoides: A New Source of Bio-Stimulants for Higher Plants idasindikizidwa pa intaneti mu magazini ya Marine Drugs ndi PROTOGA ndi Syngenta China Crop Nutrition Team. Izi zikusonyeza kuti kugwiritsa ntchito microalgae kumakulitsidwa kumunda waulimi, kufufuza kuthekera kwake kwa bio-stimulants ku zomera zapamwamba. Mgwirizano pakati pa PROTOGA ndi Syngenta China Crop nutrition team wazindikira ndikutsimikizira kuthekera kwa metabolites yakunja kuchokera m'madzi am'mbuyo a microalgae ngati feteleza watsopano wa bio, kukulitsa phindu lazachuma, kusamala chilengedwe komanso kukhazikika kwa njira yonse yopanga microalgae yamafakitale.

Kupanga ulimi wamakono kumadalira feteleza wa mankhwala kwambiri, koma kugwiritsa ntchito kwambiri feteleza wa mankhwala kunayambitsa kuipitsa chilengedwe m'nthaka, m'madzi, m'mlengalenga ndi m'zakudya. Ulimi wobiriwira umaphatikizapo chilengedwe chobiriwira, ukadaulo wobiriwira ndi zinthu zobiriwira, zomwe zimalimbikitsa kusintha kwa ulimi wa mankhwala kukhala ulimi wachilengedwe womwe umadalira kwambiri njira zamkati mwa zamoyo ndipo umachepetsa kugwiritsa ntchito feteleza wa mankhwala ndi mankhwala ophera tizilombo.

Ma microalgae ndi tizilombo tating'onoting'ono tomwe timapezeka m'madzi abwino komanso m'madzi a m'nyanja zomwe zimatha kupanga zinthu zosiyanasiyana zogwira ntchito monga mapuloteni, mafuta, ma carotenoids, mavitamini, ndi ma polysaccharides. Zanenedwa kuti Chlorella Vulgaris, Scenedesmus quadricauda, ​​Cyanobacteria, Chlamydomonas reinhardtii ndi ma microalgae ena angagwiritsidwe ntchito ngati Bio-stimulant ya beet, phwetekere, alfalfa ndi zinthu zina zaulimi zomwe zimathandiza kukulitsa kumera kwa mbewu, kusonkhanitsa zinthu zogwira ntchito komanso kukula kwa zomera.

Pofuna kugwiritsanso ntchito madzi akumbuyo ndikuwonjezera phindu lazachuma, mogwirizana ndi Syngenta China Crop Nutrition Team, PROTOGA idaphunzira za zotsatira za Auxenochlorella protothecoides tail water (EAp) pakukula kwa zomera zapamwamba. Zotsatira zake zidawonetsa kuti EAp idathandizira kwambiri kukula kwa zomera zosiyanasiyana zapamwamba komanso kupirira kupsinjika.

Tinapeza ndikuwunika ma metabolites akunja kwa thupi mu EAp, ndipo tinapeza kuti panali mankhwala opitilira 84, kuphatikizapo ma organic acid 50, mankhwala 21 a phenolic, oligosaccharides, polysaccharides ndi zinthu zina zogwira ntchito.

Kafukufukuyu akuganiza kuti njira yake yogwirira ntchito ndi iyi: 1) Kutulutsidwa kwa ma organic acid kungathandize kusungunuka kwa ma oxide achitsulo m'nthaka, motero kukulitsa kupezeka kwa zinthu zochepa monga chitsulo, zinc ndi mkuwa; 2) Mankhwala a phenolic ali ndi mphamvu zotsutsana ndi mabakiteriya kapena ma antioxidant, amalimbitsa makoma a maselo, amaletsa kutayika kwa madzi, kapena amagwira ntchito ngati mamolekyu odziwitsa, ndipo amachita gawo lofunika kwambiri pakugawikana kwa maselo, kuwongolera mahomoni, kuchita photosynthesis, mineralization ya michere ndi kuberekana. 3) Ma polysaccharides a microalgae amatha kuwonjezera kuchuluka kwa ascorbic acid ndi ntchito za NADPH synthase ndi ascorbate peroxidase, motero zimakhudza photosynthesis, kugawikana kwa maselo ndi kulekerera kwa abiotic stress kwa zomera.
