Archaea
Archaea (Graece: ἀρχαῖα 'antiqua') grex microorganismorum sunt, quorum quisque solum unam cellulam habet. Hae cellulae nucleis et ullo organello membranis ligato carent. Archaea olim putata sunt inusitatus bacteriorum grex, archaebacteria nominatus, sed quod archaeis est propria historia evolutionaria et ea in sua biochemia ab aliis vitae formis multo differunt, nunc ut dominium separatum in systemate trium dominiorum describuntur, in quo phylogenetice distincti rami originis evolutionariae sunt archaea, bacteria, et eukarya. Archaea praeterea in quattuor phyla agnota dividuntur, sed multo plura phyla fortasse adsunt. Horum gregum, crenarchaeota et euryarchaeota adsiduissime investigantur. Classificatio iam est difficilis, quod plurima archaea in laboratorio numquam investigantur, solumque studio eorum acidorum nucleicorum in speciminibus ex circumiecto extractis inventa sunt. Quamquam archaea cum bacteriis olim ut prokaryotae (in Monerorum regno) in translaticia Linnaeana quinque regnorum taxinomia posita sunt, haec classificatio est obsoleta.[4]

Ante annum 1980, archaea et eubacteria sub taxon prokaryota subsummata sunt quod organismi in ambabus congeriebus nucleis carent. Distinctionem autem inter superregna discriminatione genetica facta est a Carolo Woese, doctore in Universitate Illinoesiensi. Archaea a bacteriis duobus modis differunt:
- in structura valli, peptidoglycanum non adest, et nullus sacculus mureinicus.
- in structura membranae lipidicae, quia archaeorum duplomembranae in hydrocarbonica isomerica consistunt, combinata per ether? combinationes.?
Multae archaeorum species extremos habitant, per exemplum aquam super 373 gradus K, et aquam salinitatis magnae, acidam vel alkaliam.
Archaea morphologia et physiologia habent diversas formas: sphaericas, longas, spirales, lobatas. Diameter est ab 0.1 µm usque ad 15 µm. Procreatio est per fissione duali? sive fragmentatione. Nutritio est chemolithoautotrophica vel organotrophica, aerobica, anaerobica facultativa, anaerobica obligata.

Archaea in pervariis habitationibus fiunt. Maior oecosystematum telluris pars nunc agnoscuntur, et fortasse sunt viginti centesimae cellularum microbialium in oceanis.[7]
