Babban Bacterium Mai Ganuwa ga Idon Tsirara Da Aka Samu A Mangroves na Faransa

A wani bincike mai ban mamaki, masana kimiyya sun gano kwayar cutar da ta fi girma sau 5,000 fiye da yadda ake iya gani da ido. Kwayar halitta, Thiomargarita magnifica, tana bayyana azaman siraran fararen filaments masu aunawa kusan 1 cm tsayi. Olivier Gros, farfesa a fannin nazarin halittu na ruwa a Jami'ar des Antilles da ke Guadeloupe, ne ya gano shi a shekara ta 2009. Gros yana gudanar da bincike kan tsarin mangrove na ruwa lokacin da ya yi tuntuɓe kan wata babbar ƙwayar cuta a Guadeloupe, Faransa. An hange shi a saman ruɓaɓɓen ganyen mangrove a yankin.

Bayan haduwar, an yi nazarin kwayoyin cutar a cikin dakunan gwaje-gwaje kuma an gudanar da binciken da ba a gani ba tsawon shekaru don kammala cewa prokaryote ne na sulfur-oxidising.

"Lokacin da na gan su, na yi tunani, 'Bakon'. A farkon, ina tsammanin wani abu ne mai ban sha'awa, wasu fararen filaments waɗanda ke buƙatar haɗawa da wani abu a cikin laka kamar ganye, " ya ce Kiba.

Silvina Gonzalez-Rizzo, mataimakiyar farfesa a fannin ilimin halittu a Jami'ar des Antilles kuma marubucin farko na sabon binciken. wallafa a cikin Kimiyya, kuma ya yi jerin abubuwan 16S rRNA don gano kwayoyin halitta.

A cikin sabon binciken, ƙungiyar masu bincike daga JGI da Berkeley Lab, LRC, da Université des Antilles a Guadeloupe da sauransu, sun bayyana babbar kwayar cutar da kuma ba da haske game da siffofin kwayoyin halitta.

Gonzalez-Rizzo ta ce da farko, ta yi tunanin kwayoyin halitta eukaryotes ne domin sun yi girma da yawa kuma suna da filament masu yawa. “Mun gane cewa sun kasance na musamman domin ya yi kama da tantanin halitta guda ɗaya. Gaskiyar cewa su 'macro' microbe ne mai ban sha'awa!" Gonzalez-Rizzo ya kara da cewa bayan gano kwayoyin cutar.

A cewar Jean-Marie Volland, masana kimiyya kuma marubucin binciken, yayin da yawancin kwayoyin cutar DNA ke yawo cikin walwala a cikin cytoplasm, kwayoyin da aka gano ya sa su kasance cikin tsari. "Babban abin mamaki na aikin shine fahimtar cewa waɗannan kwafin kwayoyin halitta da aka yada a cikin dukkanin tantanin halitta suna cikin ainihin tsarin da ke da membrane," in ji shi. An gano cewa kwayoyin cutar sun fi kwayoyin halitta sau uku fiye da yadda aka sani.
