Noiʻi ʻo Microalgae Bio-stimulant Me Syngenta Kina

I kēia mau lā, ua paʻi ʻia ʻo Extracellular Metabolites of Heterotrophic Auxenochlorella protothecoides: A New Source of Bio-Stimulants for Higher Plants ma ka puke pai ʻO Marine Drugs e PROTOGA a me Syngenta China Crop Nutrition Team.Hōʻike ia i ka hoʻonui ʻia ʻana o nā noi microalgae i ka māla mahiʻai, e ʻimi ana i kona hiki i nā bio-stimulants no nā mea kanu kiʻekiʻe.ʻO ka hui pū ʻana ma waena o PROTOGA a me Syngenta China Crop meaʻai hui i ʻike a hōʻoia i ka hiki ke hiki i nā metabolites extracellular mai ka wai huelo microalgae ma ke ʻano he bio-fertilizer hou, e hoʻonui ana i ka waiwai waiwai, ka launa kaiāulu a me ka hoʻomau o ke kaʻina hana microalgae ʻoihana holoʻokoʻa.

ʻO ka hoʻoulu ʻana o ka mahiʻai o kēia wā e hilinaʻi nui ʻia i ka mea kanu kemika, akā ʻo ka hoʻohana nui ʻana i nā mea kanu kemika i hoʻohaumia i ke kaiapuni i ka lepo, ka wai, ka ea a me ka palekana o ka meaʻai.ʻO ka mahiʻai ʻōmaʻomaʻo e pili ana i ka ʻōmaʻomaʻo ʻōmaʻomaʻo, ʻenehana ʻōmaʻomaʻo a me nā huahana ʻōmaʻomaʻo, e hāpai ana i ka hoʻololi ʻana o ka mahiʻai kemika i ka mahiʻai ékological e hilinaʻi nui nei i ka mīkini kūloko kūlohelohe a hōʻemi i ka hoʻohana ʻana i nā mea kanu kemika a me nā pesticides.

ʻO Microalgae nā mea ola kiʻi kiʻi liʻiliʻi i loaʻa i loko o nā ʻōnaehana wai a me nā kai e hiki ke hana i nā mea bioactive like ʻole e like me nā protein, lipids, carotenoids, vitamina, a me polysaccharides.Ua hōʻike ʻia ʻo Chlorella Vulgaris, Scenedesmus quadricauda, ​​Cyanobacteria, Chlamydomonas reinhardtii a me nā microalgae ʻē aʻe hiki ke hoʻohana ʻia e like me Bio-stimulant no ka beet, tomato, alfalfa a me nā huahana mahiʻai ʻē aʻe e kōkua i ka hoʻomaikaʻi ʻana i ka germination hua, ka hoʻoulu ʻana o nā mea ikaika a me ka ulu ʻana o nā mea kanu.

I mea e hoʻohana hou ai i ka wai huelo a hoʻonui i ka waiwai waiwai, me ka hui pū me Syngenta China Crop Nutrition Team, ua aʻo ʻo PROTOGA i nā hopena o Auxenochlorella protothecoides tail water (EAp) i ka ulu ʻana o nā mea kanu kiʻekiʻe.Ua hōʻike ʻia nā hopena ua hoʻoikaika nui ʻo EAp i ka ulu ʻana o nā ʻano mea kanu kiʻekiʻe a hoʻomaikaʻi i ke kūpaʻa koʻikoʻi.

Ua ʻike a loiloi mākou i nā metabolites extracellular ma EAp, a ua ʻike ʻia he ʻoi aku ma mua o 84 mau pūhui, me 50 mau ʻakika organik, 21 pūhui phenolic, oligosaccharides, polysaccharides a me nā mea hana ʻē aʻe.

Ke manaʻo nei kēia haʻawina ʻo kāna hana hiki ke hana: 1) Hiki i ka hoʻokuʻu ʻana i nā ʻakika organik ke hoʻoikaika i ka hoʻoheheʻe ʻana o nā ʻokikene metala i loko o ka lepo, pēlā e hoʻomaikaʻi ai i ka loaʻa ʻana o nā mea e like me ka hao, ka zinc a me ke keleawe;2) Loaʻa i nā pūhui Phenolic nā hopena antibacterial a i ʻole antioxidant, e hoʻoikaika i nā paia o ke kelepona, e pale i ka nalowale o ka wai, a i ʻole ka hana ma ke ʻano he molekala hōʻailona, ​​​​a pāʻani i kahi kuleana nui i ka mahele cell, hoʻoponopono hormone, photosynthetic activity, mineralization nutrient and reproduction.3) Hiki i ka microalgae polysaccharides ke hoʻonui i ka ʻike o ka ascorbic acid a me nā hana o NADPH synthase a me ascorbate peroxidase, no laila e hoʻopili ai i ka photosynthesis, ka māhele cell a me ka hoʻomanawanui koʻikoʻi abiotic o nā mea kanu.
