It belong in Eubacteria
Eubacteria are unicellular, heterotrophic prokaryotic cells and are ubiquitous (can be found everywhere). The cells of Eubacteria lack a true nucleus and some organelles such as mitochondrions or chloroplasts. They possess a rigid cell wall that is composed of peptidoglycan and a cell membrane that is made up of a phospholipid bilayer. Eubacteria usually reproduce asexually through the process of binary fission.
