Kurangiza "Ikintu Cyijimye"? Ivumburwa ryubwoko bushya bwa Methanogenic Archaea

Vuba aha, itsinda rya anaerobic rishya ryo guhanga udushya tw’ikigo cy’ubushakashatsi cya siyanse ya Biogas muri Minisiteri y’ubuhinzi n’ibikorwa by’icyaro (aha ni ukuvuga "Ikigo cy’ubumenyi cya Biogas"), ku bufatanye na kaminuza ya Wageningen mu Buholandi n’ibindi bigo, bavumbuye kandi bonyine kandi bahinga. ubwoko bushya bwa methanogenic archaea. Ibisubizo bijyanye byatangajwe muri Kamere.

Archaea ya Methanogenic nimwe mubuzima bwa kera cyane ku isi, bugaragara ku isi hashize imyaka miriyari 3.46. Archaea ya Methanogenic igira uruhare runini mubinyabuzima bisanzwe byisi. Kurugero, methaneque archaea itanga 70% byuka metani yisi yose. Methane ni gaze ya kabiri nini ya parike nyumaDioxyde de carbone, n'ingaruka zayo zo gushyushya zikubye inshuro 28 izoDioxyde de carbone, bingana na 20% byingaruka zisi yose. Byongeye kandi, archaea methanogenic igira uruhare mugikorwa cyo guhindura ibinyabuzima byo munsi y'ubutakamethanenaDioxyde de carbone, kandi ugire uruhare runini muri karubone yisi yose. Methanogenic archaea ishinzwe gutunganya 2% bya karubone kwisi buri mwaka.

Imyumvire gakondo nuko archaea methanogenic ari iyitwa phylum Euryarchaeota murwego rwa Archaea. Mu myaka yashize, hashingiwe ku bushakashatsi bw’ibanze, umuryango w’amasomo wasabye ko archaea itari Erythroarchaeota methanogenic ikwirakwizwa cyane muri kamere, bakavuga ko usibyekubyara metani, aba archaea bashya nabo bafite ubushobozi kubatari-methanemetabolism nko gukura kwa fermentation na okiside ya sulfure.

"Archaea Methanogenic ni ubwoko bwa mikorobe ikura itanga metani kugirango ibone ingufu, ariko niba nayo idafite-methaneubushobozi bwa metabolike nko gukura kwa fermentation hamwe na okiside ya sulfuru, uruhare rwa archaea ya methanogeneque mu kuzenguruka isi ku isi bizahinduka ", ibi bikaba byavuzwe na Cheng Lei, umwanditsi uhuye n’uru rupapuro akaba n'umuhanga mu bumenyi bw’itsinda rishya rya anaerobic rishya ry’ikigo cy’ibinyabuzima. kure, aba archaea bari mubintu "byijimye" kandi nta muco wabayeho, bityo iki gitekerezo nticyemejwe nubushakashatsi.

Ijambo "umwijima" bivuga ko abahanga babonye genome ya archaea hakoreshejwe ikoranabuhanga rikurikirana, ariko kuba hariho genes ntibisobanura ko bizagaragazwa, ni ukuvuga ko bidashoboka byanze bikunze gukorera ibidukikije. Kubwibyo, kugirango twemeze iki gitekerezo, birakenewe gutandukanya archaea, kubona umurongo umwe, ni ukuvuga umuco wera, hanyuma ugakora ubushakashatsi bwibikorwa bya physiologique kugirango tumenye imiterere ya gene.

Ku gitekerezo cya Dong Xiuzhu, umushakashatsi mu kigo cya Microbiology, Ishuri Rikuru ry’Ubumenyi ry’Ubushinwa, ubu bushakashatsi buvuga ko itsinda rya mbere rishya ryabayeho mu bwihindurize bwa methanogenic archaea itari iya gakondo, ryagura urugero rwa archeya methanogene. Byongeye kandi, ubu bwoko bwa archaea butanga metani mukugabanya ibintu bya methyl hamwe na hydrogène hamwe ninzira zabo za metabolike bikwirakwizwa cyane mubutaka bwisi butabura ogisijeni munsi yisi, byerekana ko bitanga umusanzu wingenzi kwisi yosemethaneimyuka ihumanya ikirere.
