Microalgae Bio-stimulant Suesuega ma Syngenta Saina
Talu ai nei, Extracellular Metabolites of Heterotrophic Auxenochlorella protothecoides: A New Source of Bio-Stimulants for Higher Plants na lomia i luga o le initaneti i le api talaaga Marine Drugs e PROTOGA ma Syngenta China Crop Nutrition Team.O lo'o fa'ailoa mai ai o lo'o fa'alauteleina le fa'aogaina ole microalgae ile fa'ato'aga, su'esu'e lona gafatia o meaola fa'aola mo laau maualuluga.O le galulue faʻatasi i le va o le PROTOGA ma le Syngenta China Crop nutrition team ua faʻamaonia ma faʻamaonia le faʻaogaina o metabolites extracellular mai microalgae siʻusiʻu vai e avea o se bio-fertilizer fou, faʻaleleia le tau o le tamaoaiga, faʻafeiloaʻi o le siosiomaga ma le faʻaauauina o le gaosiga o microalgae gaosiga uma.
▲Ata 1. Tala fa'atusa
O le gaosiga o fa'ato'aga fa'aonaponei e fa'alagolago lava i le fa'ama'i vaila'au i se tulaga tele, ae o le fa'aogaina tele o vaila'au vaila'au na mafua ai le fa'aleagaina o le si'osi'omaga i le palapala, vai, ea ma le saogalemu o mea'ai.Fa'ato'aga lanu meamata e aofia ai le si'osi'omaga lanu meamata, tekinolosi lanu meamata ma oloa lanu meamata, lea e fa'aolaina ai le suiga o fa'ato'aga vaila'au i fa'ato'aga si'osi'omaga lea e fa'alagolago tele i le fa'aogaina o meaola i totonu ma fa'aitiitia le fa'aogaina o vaila'au fa'ama'i ma vailaau fa'asaina.
O microalgae o ni mea fa'aola fa'atosina laiti o lo'o maua i vai fou ma gataifale e mafai ona gaosia le tele o mea ola fa'aola e pei o polotini, lipids, carotenoids, vitamini, ma polysaccharides.Ua lipotia mai o Chlorella Vulgaris, Scenedesmus quadricauda, Cyanobacteria, Chlamydomonas reinhardtii ma isi microalgae e mafai ona faʻaaogaina e avea ma Bio-stimulant mo beet, tamato, alfalfa ma isi mea faʻatoʻaga e fesoasoani e faʻaleleia le germination fatu, faʻaputuina o mea aoga ma le tuputupu ae o laau.
Ina ia mafai ona toe faʻaaogaina le vai o le siʻusiʻu ma faʻateleina le tau o le tamaoaiga, i le galulue faʻatasi ai ma le Syngenta China Crop Nutrition Team, na suʻesuʻeina e le PROTOGA aafiaga o le Auxenochlorella protothecoides tail water (EAp) i luga o le tuputupu aʻe o laau maualuluga.O fa'ai'uga na fa'aalia ai o le EAp na matua fa'atupuina le tuputupu a'e o ituaiga eseese o la'au maualuluga ma fa'aleleia atili ai le fa'alavelave.
▲Ata 2. EAp Aafiaga o le EAp i laau fa'ata'ita'i
Na matou faailoaina ma suʻesuʻeina metabolites extracellular i le EAp, ma maua ai e sili atu nai lo le 84 mea faʻapipiʻi, e aofia ai le 50 organic acids, 21 phenolic compounds, oligosaccharides, polysaccharides ma isi mea aoga.
O lenei suʻesuʻega e faʻapea o lona faʻaogaina o gaioiga: 1) O le tuʻuina atu o meaola faʻalaʻau e mafai ona faʻalauteleina le faʻamavaeina o uʻamea uʻamea i le palapala, ma faʻaleleia atili ai le maua o elemene e pei o le uʻamea, zinc ma le kopa;2) Phenolic compounds ei ai aʻafiaga antibacterial poʻo antioxidant, faʻamalosia puipui puipui, puipuia le gau o le vai, poʻo le galue e pei o mole mole faʻailoga, ma faia se sao taua i le vaeluaga o le cell, faʻatonutonuina o hormone, gaioiga photosynthetic, mineralization nutrient ma le toe gaosia.3) Microalgae polysaccharides e mafai ona faʻateleina mea o loʻo i totonu o le ascorbic acid ma gaioiga a le NADPH synthase ma le ascorbate peroxidase, ma faʻapea ona aʻafia ai le photosynthesis, cell division ma le faʻapalepale faʻamaʻi abiotic o laau.
