Litlhaloso tse ncha mabapi le hore na cyanobacteria e laola ho kenngoa ha zinki joang maoatleng a phahameng ScienceDaily

Marine cyanobacteria (blue-green algae) ke karolo e kholo ea potoloho ea khabone lefatšeng ka bophara 'me ke motheo oa lijo tse ngata tsa leoatleng tsa lefatše. Li hloka feela khanya ea letsatsi, carbon dioxide, le sehlopha sa lintho tsa motheo, ho kenyeletsoa litšepe, ho boloka bophelo. ha ho tsejoe hakaalo ka hore na cyanobacteria e sebelisa kapa e laola zinki joang, e leng ntho eo ka kakaretso e nkoang e le ea bohlokoa bophelong.
Sehlopha sa lipatlisiso sa lihlopha tse fapaneng tsa litho tse 'nè tse tsoang Univesithing ea Warwick se khethile marang-rang a taolo a sebetsang hantle haholo a laolang ho bokellana ha zinki maoatleng a phahameng a cyanobacteria Synechococcus.
Marang-rang ana a lumella Synechococcus hore e fetole maemo a eona a ka hare a zinki ka litaelo tse fetang tse peli tsa boholo 'me e itšetlehile ka protheine e laolang ea ho nka zinki (Zur), e utloang zinki le ho arabela ka tsela e nepahetseng.
Ka mokhoa o ikhethileng, protheine ea sensor ena e kenya baktheria metallothionein (protein e tlamang zinki) eo, hammoho le sistimi e sebetsang hantle ea ho e amohela, e ikarabellang bakeng sa bokhoni bo makatsang ba 'mele ba ho bokella zinki.
Moprofesa Claudia Blindauer, oa Lefapha la Khemistri ea Univesithi ea Warwick, o itse: “Liphetho tsa rōna li bontša hore zinki ke ntho ea bohlokoa bakeng sa cyanobacteria ea leoatleng.Bokhoni ba tsona ba ho boloka zinki bo ka ’na ba thusa ho ntlafatsa ho ntšoa ha phosphorus, e haellang haholo likarolong tse ngata tsa maoatle a lefatše.Ke macronutrient.Zinc e kanna ea hlokahala bakeng sa ho lokisa khabone hantle. ”
Ngaka Alevtina Mikhaylina oa Warwick School of Life Sciences o ile a hlalosa: “Likarolo tsena, tse e-s’o tlalehoe bakeng sa baktheria leha e le efe e ’ngoe, li ka tlatsetsa ho ateng ha tikoloho ea Synechococcus maoatleng a lefatše.Re tšepa hore liphetho tsa rona li tla khahla bafuputsi haholo., ho tloha ho litsebi tsa k’hemik’hale ea lintho tse phelang (haholo-holo litsebi tsa k’hemik’hale tsa tšepe le tsa bioinorganic), litsebi tsa thuto ea kaho le limolek’hule ho ea ho litsebi tsa thuto ea lintho tsa tlhaho, litsebi tsa lintho tse phelang le tikoloho ea tsona tse nyenyane le litsebi tsa maoatle.”
Ngaka Rachael Wilkinson ho tsoa Sekolong sa Bongaka sa Swansea University le Moprofesa Vilmos Fülöp oa Sekolo sa Life Sciences Univesithing ea Warwick ba ekelitse: "Joaloka karolo ea projeke e fapaneng, sebopeho sa protheine ea Zur se fana ka leseli mabapi le hore na e bapala karolo ea bohlokoa joang ho laola maoatle Zinc homeostasis ho cyanobacteria.
Ngaka James Coverdale, oa Univesithi ea Birmingham’s Institute of Clinical Sciences, o hlokometse: “Ka ho sebetsa tumellanong le khokahanyo ea microbiology, tlhahlobo, sebopeho le k’hemistri, sehlopha sa rōna sa lihlopha tse fapaneng se ntlafalitse kutloisiso ea rōna haholo ea kamoo k’hemik’hale ea inorganic e amang bophelo ba leoatle.””
Moprofesa Dave Scanlan oa Warwick School of Life Sciences o ile a phaella: “Leoatle ke ‘letšoafo’ le batlang le hlokomolohuoa la polanete ea rōna – phefumoloho e ’ngoe le e ’ngoe eo re e hemang ke oksijene e ’nileng ea hlaha tsamaisong ea maoatle, ha hoo e ka bang halofo ea Thepa ea carbon dioxide e le ka har’a biomass. e etsahalang Lefatsheng ka metsing a lewatle.Li-cyanobacteria tsa metsing ke libapali tse ka sehloohong "matšoafong" a Lefatše, 'me buka ena e ngotsoeng ka letsoho e senola karolo e ncha ea baeloji ea bona, bokhoni ba ho laola homeostasis ea zinki, e leng lintlha tse ba thusang ho finyella bokhoni bona ba bohlokoa ba mesebetsi ea lipolanete.
