Mufananidzo - Boran Kartal
Zvinotaridza kuti pane pekupedzisira mushonga uyo, kunze kwekushanda, unonyanya kunakidza. Zviri nezve utachiona kubva pakurongeka kweMethanosarcinales iyo yakawanikwa neboka revatsvagiri vanobva kuRadBoud University, kuNetherlands, uye Max Planck Institute for Marine Microbiology muBremen, Germany, avo vakagadzirira chidzidzo chakaburitswa mu rondedzero Proceedings yeNational Academy yeSainzi.
Kutsvaga kunonakidza kunogona kumiririra, pasina kukahadzika, pamberi nepashure mukurwira mhedzisiro inogona kuunza kudziya kwepasi.
Vatsvagiri vakatofungira kuti kune hutachiona hunogona kudya, kwete chete methane, asiwo ayini, asi kusvika zvino vanga vasati vaiwana. Neraki, ivo vawana arch iyo inoshandisa iron kushandura methane kuita kabhoni dhayokisaidhi. Nekudaro, iyo inoderedza huwandu hwesimbi hunowanikwa kune mamwe mabhakitiriya, nokudaro ichitangisa simba rinobuda iro rinokanganisa iyo iron-methane kutenderera nekubuda kwayo.
Uye sekunge izvi zvaive zvisina kukwana, idzi archaea dzinogona kushandura nitrate kuita ammonium, chinova chikafu chemamnox bacteria, ayo chinja ammonia kuita nitrogen… Pasina kushandisa oxygen! Izvi zvinonyanya kukosha pakurapa kwemvura yakasviba, sezvakaratidzwa naBoran Kartal, microbiologist kuMax Planck Institute, uyo akawedzera kuti:
Bioreactor ine anaerobic methane uye ammonium oxidizing microorganisms inogona kushandiswa panguva imwe chete kushandura ammonium, methane uye oxidized nitrogen mumvura yakasviba kuita nitrogen gasi uye kabhoni dhayokisaidhi, iyo ine yakanyanya kuderera kupisa kwepasi.
Archaea inogona kubatsira kwazvo mumvura yakasviba.
Kunyangwe ivo vaiziva nezve kuvapo kweaya masimbi-anoenderana nemethane oxidants, ivo vanga vasina kukwanisa kuzvitsaura. Nekudaro, ivo vakakwanisa kuvawana mune yavo yega sampuro yekuunganidza, uye ikozvino vanogona kushandiswa kudzora kudziya kwepasi
Unogona kuverenga chidzidzo pano (muChirungu).
