Microalgae Bio-stimulant Research neSyngenta China

Munguva pfupi yapfuura, Extracellular Metabolites yeHeterotrophic Auxenochlorella protothecoides: Nyowani Itsva yeBio-Stimulants yeZvirimwa Zvepamusoro yakaburitswa online mujenari Marine Drugs nePROTOGA uye Syngenta China Crop Nutrition Team.Zvinoratidza kuti mashandisirwo emicroalgae anowedzerwa kumunda wekurima, uchiongorora kugona kwayo kwebio-stimulants yezvidyarwa zvepamusoro.Kudyidzana pakati pePROTOGA neSyngenta China Chikwata chekudya chekudyara chakaona uye chakasimbisa kugona kweextracellular metabolites kubva mumvura yemuswe wemicroalgae sechinhu chitsva chebio-fertilizer, ichiwedzera kukosha kwehupfumi, hushamwari kwezvakatipoteredza uye kusimba kweyese indasitiri yekugadzira microalgae.

Kugadzirwa kwemazuva ano kwekurima kunoenderana nemakemikari fetiraiza kusvika pamwero mukuru, asi kushandiswa kwakanyanya kwemakemikari fetiraiza kwakakonzera kusvibiswa kwezvakatipoteredza muvhu, mvura, mhepo uye kuchengetedza chikafu.Kurima kwegirinhi kunosanganisira nharaunda yakasvibira, tekinoroji yegirinhi uye zvigadzirwa zvakasvibirira, izvo zvinosimudzira shanduko yekurima kwemakemikari kune ecology yekurima iyo inonyanya kutsamira pane biological mukati memaitiro uye inoderedza kushandiswa kwemakemikari fetiraiza nemishonga yekuuraya zvipembenene.

Microalgae zvipenyu zvidiki zvephotosynthetic zvinowanikwa mumvura yakachena uye marine masisitimu anokwanisa kugadzira akawanda akasiyana bioactive zvinhu zvakaita semapuroteni, lipids, carotenoids, mavhitamini, uye polysaccharides.Izvo zvakataurwa kuti Chlorella Vulgaris, Scenedesmus quadricauda, ​​Cyanobacteria, Chlamydomonas reinhardtii uye mamwe macroalgae anogona kushandiswa seBio-stimulant yebeet, tomato, alfafa uye zvimwe zvigadzirwa zvekurima zvinobatsira kuvandudza kumera kwembeu, kuunganidza kwezvinhu zvinoshanda uye kukura kwezvirimwa.

Kuti ushandise zvakare mvura yemuswe uye kuwedzera kukosha kwehupfumi, nekubatana neSyngenta China Crop Nutrition Team, PROTOGA yakadzidza mhedzisiro yeAuxenochlorella protothecoides tail water (EAP) pakukura kwezvirimwa zvepamusoro.Zvigumisiro zvakaratidza kuti Eap yakakurudzira zvikuru kukura kwemarudzi akasiyana-siyana emiti yepamusoro uye nekuvandudza kusagadzikana kwekunetseka.

▲ Mufananidzo 2. Eap Mhedzisiro yeEAP pamhando yemiti

Takaona uye takaongorora extracellular metabolites muEAP, uye takaona kuti pane zvinopfuura 84 makemikari, kusanganisira 50 organic acids, 21 phenolic compounds, oligosaccharides, polysaccharides nezvimwe zvinhu zvinoshanda.

Ichi chidzidzo chinofungidzira maitiro ayo anogona kuita: 1) Kuburitswa kweasidhi yeorganic kunogona kukurudzira kunyungudika kwesimbi okisidhi muvhu, nekudaro kunatsiridza kuwanikwa kwezvinhu zvekutevera zvakaita sesimbi, zinc uye mhangura;2) Phenolic compounds ine antibacterial kana antioxidant effect, inosimbisa masero emadziro, kudzivirira kurasikirwa kwemvura, kana kushanda sechiratidzo chemolekemu, uye inoita basa rinokosha mukuparadzanisa kwesero, kutonga kwehomoni, basa rephotosynthetic, mineralization yezvokudya uye kubereka.3) Microalgae polysaccharides inogona kuwedzera zvinyorwa zve ascorbic acid uye mabasa eNADPH synthase uye ascorbate peroxidase, nokudaro inokanganisa photosynthesis, kupatsanurwa kwesero uye abiotic stress kushivirira kwezvirimwa.
