Litaba
The libaktheria ke libopuoa tse phelang unicellular me ba joalo likokoana-hloko tsa prokaryotic. Sena se bolela hore semela sa eona sa lefutso, e leng molek'hule ea DNA e chitja habeli, se lokolohile ka cytoplasm, ha e koalloa ka har'a khubu.
Kaha li-microfossil le stromatolites (likoli tsa libaktheria tse tsoakiloeng le liminerale) li fumanoe litsing tse tsoang mehleng e fapaneng ea jioloji, esita le majoeng a khale ho feta Lilemo tse limilione tse likete tse 3,5, ho boleloa hore libaktheria li bile teng ho tloha mehleng ea khale haholo.
Haholo hoo ba bileng teng ka nako e telele ea nalane ea Lefatše moo ho neng ho se na mefuta e meng ea bophelo. Ebile, libaktheria li hlahisitse liketsahalo tsa bohlokoa haholo tsa ho iphetola ha lintho.

Mefuta ea libaktheria
Hangata kajeno e aroloa ka lihlopha tse peli tse kholo:
- Libaktheria: ba emeloa ke laola tikolohong ea tlhaho kajeno, ka boteng ba maemo a fapaneng a oksijene le metabolism tse fapaneng.
- Archaea: ho iphetola ha lintho emela a sehlopha se fetileng, ka metabolism tse ikamahantseng le maemo a feteletseng a tikoloho, joalo ka khaello ea oksijene (hopola hore, ho latela lithuto tse matla, ho ne ho se na oksijene polaneteng ho fihlela meroho, libololi tse kholo tsa oksijene li hlaha), kapa letsoai haholo kapa libaka tse nang le asiti e ngata le mocheso o phahameng.
E kholo katleho ea ho iphetola ha lintho baktheria e bakoa haholo ke ho li makatsa ha bona metabolic versatility. Ho ka boleloa hore mekhoa eohle e ka bang teng ea ho fumana taba le matla li teng li ajoa ka mefuta e fapaneng ea libaktheria.

Bohlokoa
The libaktheria Li na le bohlokoa ba tlhaho, hobane li teng lipotolohong tsa tlhaho tsa likarolo tsa bohlokoahali bophelong: naetrojene, khabone, phosphorus, sebabole, jj.

Litšobotsi
The libaktheria Li microscopic mme kantle ho lera le koalang cytoplasm ea tsona ho na le sebopeho se bitsoang lebota la sele. Ho feta moo kantle, libaktheria tse ling li theha sebopeho se kang jelly se bitsoang komiki.
Libaktheria li ikatisa ka ho aroha ka mokhoa o ts'oanelang 'me ka potlako haholo, ka hona li ngata haholo. Ka lebaka la metabolism ea bona e fapaneng haholo, ba ka atleha libakeng tse ngata tse kang:
