Lolu cwaningo lusekelwa uhlelo lukaMongameli lweRussia Science Foundation (RNF) futhi lushicilelwe kumagazini weSayensi yemibiko yeSayensi. I-Diatoms algae, noma ama-diatoms - i-algae eyodwa, ihlala cishe kuyo yonke indawo - ivela enhlabathini naseqhweni kuya kuma-reservoirs amasha. Isici sabo esihlukile uhlobo lwe- "Shell" oluvela eSilica Dioxide, esimweni esifana nensipho noma ibhokisi lesicathulo - i-sash eyodwa incane kancane futhi ingena okwesibili.
Iphethini elincanyana ku- "Shell" liyisici esibalulekile sokuthola i-kinship phakathi kwezinhlobo ezahlukene ze-algae. Manje phakathi kwama-diatoms kukhona izinhlobo eziyizinkulungwane ezingama-20-25, ezakha ikota yalo lonke udaba lwe-organic emhlabeni. Ama-systestics abo avuselelwa njalo ngenxa yokuvela kwezindlela ezintsha, ezithuthukile kakhulu zokuhlaziywa kwe-microscopy kanye ne-molecular.
I- "Hantzschia luhlobo lwe-diatom algae, abamele abakhona ezindaweni ezahlukahlukene. Sifunde le sakhiwo kanye nezibopho zenhlabathi ezingama-25 zenhlabathi ye-diatom algae, ezifundweni zangaphambilini ezingabangelwa uhlobo lwe-hantzschia amphioxys. Izifundo zezakhi zofuzo ezinemininingwane ezinemininingwane nezinkokhelo zikhombisile ukuthi lezo zinhlobo eziyisikhombisa ezihlukile ze-hantzschia, kufaka phakathi i-brand entsha yesayensi, "kusho ukhetho lwesayensi emihlanu yesayensi, inhloko yephrojekthi yeSibonelelo se-RNF, umcwaningi oholayo, isikhungo sesitshalo I-Physiology ebizwa nge-K. A. Timiryazev (IFS) RAS.
Emsebenzini wabo, ososayensi baphenya ama-algae anikezwe inhlabathi nasehlathini lasehlathini ezingxenyeni ezahlukene ze-Eurasia, kanye namasiko amaningana ukusuka e-Geta University Collection (Belgium). Amasampula ahlukaniswe yaba yizinhlobo ze- "Shell" nephethini kulo, kanye nokuqhathanisa ukulandelana kwe-DNA - ukuba anembe kakhudlwana, izinhlobo ezimbili ze-ribosomal kanye ne-chloropsts eyodwa.
Ukutadisha izembozo ezisetshenziselwe ama-microscopy asetshenziswa ngogesi. Ngenxa yalokho, kutholwe izinhlobo ezintsha ezinhlanu, kufaka phakathi okuhlukile okumbalwa kule ndawo. Ngasikhathi sinye, phambilini bekukholelwa ukuthi kusukela kuGenus Hantzschia enhlabathini ye-Eurasia kuphela izinhlobonhlobo zezilwane - ama-cosmopolitans, okungukuthi, lezo ezivame kuwo wonke umhlaba.
Lolu cwaningo lungabizwa ngokuthi luthakazelisa hhayi kuphela ngombono wethiyori. I-Diatoms algae ihlanganisa izinto eziningi eziwusizo - ngokwesibonelo, i-Omega-3. Leli yiqembu lama-acid angenasisekelo alungile, agcina izinga elijwayelekile le-cholesterol egazini futhi yingxenye ephoqelekile yokudla okulinganiselayo.
"Inani le-diatom algae ukuthi likhula ngokushesha futhi lingaqongelela izinto eziwusizo ngisho nokuntuleka kwamandla ku-Medium. Izingqinamba ezintsha ze-algae zingaba yinhloko yokuthola izindlela ezithuthukisiwe zokukhiqiza zezinto ezibalulekile kumuthi, kanye nokulima nokudoba. Iqoqo elenziweyo le-Hantzschia, lihlukaniswe nendawo ekude nasendaweni ehlukile - liku-Ecosystems, lizosiza kulokhu, "lizophetha u-Evgeny Maltseli.
