Nghọta ọhụrụ banyere ka cyanobacteria si ahazi oriri zinc na oke osimiri ScienceDaily

Mmiri cyanobacteria (acha anụnụ anụnụ-green algae) bụ isi ihe na-enye aka na gburugburu ụwa carbon okirikiri na n'okpuru ọtụtụ n'ime ụwa nri webs. Ha chọrọ ìhè anyanwụ, carbon dioxide, na a set nke isi ihe, gụnyere ọla, na-akwado ndụ. Otú ọ dị, A maghị nke ọma ma na otú cyanobacteria si eji ma ọ bụ na-achịkwa zinc, ihe a na-ewerekarị dị ka ihe dị mkpa na ndụ.
Otu nyocha nke interdisciplinary nke ndị otu anọ sitere na Mahadum Warwick achọpụtala otu netwọk nchịkwa na-arụ ọrụ nke ọma nke na-achịkwa mkpokọta zinc n'oké osimiri cyanobacteria Synechococcus.
Netwọk a na-enye Synechococcus ohere ịgbanwe ọkwa zinc dị n'ime ya site n'ihe karịrị iwu abụọ nke ịdị ukwuu ma dabere na protein protein na-ewelite zinc (Zur), nke na-ahụta zinc wee zaghachi ya.
N'ụzọ pụrụ iche, protein sensọ a na-eme ka nje bacteria metallothionein rụọ ọrụ (protein na-ejikọta zinc) nke, yana usoro nnabata nke ọma, na-ahụ maka ikike pụrụ iche nke akụkụ ahụ nwere ịkwakọba zinc.
Prọfesọ Claudia Blindauer, bụ́ onye na Ngalaba Na-ahụ Maka Chemistry na Mahadum Warwick, kwuru, sị: “Nsonaazụ anyị na-egosi na zinc bụ ihe dị mkpa maka cyanobacteria mmiri.Ikike ha ịchekwa zinc nwere ike inye aka kwalite mwepụ nke phosphorus, nke dị ụkọ n'ọtụtụ akụkụ nke oke osimiri ụwa.A macronutrient.Enwere ike ịchọ Zinc maka ndozi carbon nke ọma."
Dr Alevtina Mikhaylina sitere na Warwick School of Life Sciences kwuru, sị: “Ihe ndị a, bụ́ nke a na-akọbeghị maka nje bacteria ọ bụla ọzọ, pụrụ iso mee ka Synechococcus kesa gburugburu ebe obibi n'oké osimiri zuru ụwa ọnụ.Anyị na-atụ anya na nchoputa anyị ga-amasị ndị nyocha., site n’aka ndị ọkà mmụta ihe ndị dị ndụ (karịsịa trace metal and bioinorganic chemists), ndị ọkà mmụta ihe n’usoro na ihe ndị dị ndụ ruo na ndị ọkà n’ihe banyere ihe ndị dị ndụ, ndị na-ahụ maka ihe ndị dị ndụ n’ihe banyere ihe ndị dị ndụ na ihe ndị dị n’oké osimiri.”
Dr Rachael Wilkinson sitere na ụlọ akwụkwọ ahụike Mahadum Swansea na Prọfesọ Vilmos Fülöp sitere na School of Life Sciences na Mahadum Warwick gbakwụnyere, sị: “Dịka akụkụ nke ọrụ mmekọrịta, nhazi nke protein Zur na-enye nghọta n'usoro n'usoro o si arụ ọrụ ya bụ isi na ya. na-achịkwa oke osimiri Zinc homeostasis na cyanobacteria."
Dọkịta James Coverdale, nke Mahadum Birmingham’s Institute of Clinical Sciences, kwuru, sị: “N’ịrụ ọrụ n’ihe banyere microbiology, analysis, structure and biochemistry, otu anyị na-arụkọ ọrụ ọnụ emewo ka nghọta anyị nke ọma banyere otú kemịkalụ inorganic si emetụta ndụ mmiri.””
Prọfesọ Dave Scanlan nke Warwick School of Life Sciences gbakwụnyere, sị: “Oké osimiri bụ 'akpa ume' nke ụwa anyị a na-eleghara anya - ume ọ bụla anyị na-eku bụ oxygen sitere n'usoro oké osimiri, ebe ihe dị ka ọkara bụ nhazi nke carbon dioxide na biomass. na-eme n'ụwa na mmiri mmiri.cyanobacteria mmiri bụ isi egwuregwu na "akpa ume" ụwa, ihe odide a na-ekpughe akụkụ ọhụrụ nke usoro ihe ọmụmụ ha, ikike ịhazi zinc homeostasis nke ọma, nke atụmatụ na-enyere ha aka iru ike ndị a dị egwu nke ọrụ mbara ala.
