These organisms differ from the eubacteria in the strucutre of their cell membrane and cell wall.Three Main Phyla In the Archaebacteria Kingdom. 1  These organims are anerobic methane producers that produce nearly 2 trillion kg of methane gas annually.hese organisms are able to adapt to extreme enviormental conditions.
