Uchrashi

tahrir

Odamning ogʻiz boʻshligʻidan TM7x uchraydi va TM7x juda kichik kokk o‘lchamiga ega bo‘lib (200-300 nm ekanligini aniqladi), insoniyatga maʼlum boʻlgan mikroblarda ilgari kuzatilmagan oʻziga xos hayot tarziga ega boʻlgan[3]. Bu bakteriyalar turli xildagi tuzilishga ega boʻlib, epibiontikligi, jumladan Actinomyces odontolyticus shtammi (XH001), shu bilan birga parazitar fazaga ega boʻlishi bilan farqlanadi. Toʻliq genom ketma-ketligi juda kamaygan (705 kB)[4] va aminokislotalarning biosintetik qobiliyatining toʻliq yetishmasligini aniqlangan. 2014-yilda ogʻiz boʻshligʻidan TM7x aksenik hayot sikli haqida xabar berilgan[5].

Candidate Phylum TM6[6] bilan bir qatorda, 1994-yilda Germaniyadagi torf botqogʻining tuproq namunasini atrof-muhitni oʻrganishda olingan namunalar ketma-ketliklari sharafiga nomlangan boʻlib, bu yerda 262 PCR kuchaytirilgan 16S rDNK fragmentlari Torf, Mittlere Schicht uchun TM klonlari deb nomlangan plazmid vektoriga klonlangan. Torf, Mittlere Schicht (lit. torf, oʻrta qatlam)[7]. U bir nechta muhitda topilgan, masalan, botqoqliklardan[8][9], suv tozalash inshootlaridan[10], tropik oʻrmon tuprogʻidan[11], inson soʻlagidan[12], [13] gubkalar bilan bogʻliq holatlardan[14], suvaraklardan[15], oltin konlaridan[16], asetat bilan oʻzgartirilgan suvli qatlam choʻkindilaridan[17] va boshqa muhitlardan topilgan (bar termofil). Yaqinda TM7 rDNK va butun hujayralar inson terisiga 99,7% TM7 va 98,6% inson ogʻziga TM7a bilan oʻxshashlik bilan tuproqlarda aniqlandi[18], atrof-muhit joylarida metabolik faol TM7 izolatlari model organizmlar boʻlib xizmat qilishi mumkin. TM7 turlarining inson salomatligidagi rolini oʻrganilmoqda.

Xususiyatlari

tahrir

TM7 oʻziga xos FISH problari bioreaktor loyidan aniqlangan turlarini gram-musbat hujayra konvertlari va bir nechta morfotiplar mavjudligini aniqladi: qobiqli filament (koʻp), qisqa zanjirlarda uchraydigan tayoqchalari, qalin filament va kokklari; birinchisi Eikelboom 0041 turining sababi boʻlishi mumkin (faollashtirilgan shtammlarining koʻpayishi bilan bogʻliq muammolar)[19]. Bakteriyalar oilasining aksariyati gram-manfiy didermalar koʻrinishida boʻlib, faqat Bacillota, Actinomycetota va Chloroflexota monodermlari koʻp uchraydi[20]. Saccharibacteria guruhiga oid 50 dan ortiq turli xil filotiplar aniqlangan boʻlib[21] u nisbatan oddiy intradivizion 16S rDNK ketma-ketligi 17% ni tashkil qiladi, bu koʻrsatgich 13 dan 33% gacha[22] jsPhyloSVG[23][24] qurilgan TM7 ning interaktiv filogenetik daraxti GenBank ketma-ketliklariga va daraxt shoxlari orasidagi masofa matritsasi hisoblariga tez kirish imkoniyatini berishi oʻziga xos xususiyatidir.

Barqaror izotoplarni tekshirish tadqiqotlari ushbu turlarning baʼzi aʼzolari toluolni parchalashi mumkinligini aniqlaganlar[25][26].
