Taxonomy. Bacteria are members of the prokaryote group. In contrast to eukaryote cells, bacteria lack a cell nucleus and customarily have no organelles. The bacteria domain can be grouped into two major categories: (a) Eubacteria and (b) Cyanobacteria.here are approximately 50 million bacterial organisms in a single gram of typical surface soil. The worldwide bacterial biomass exceeds that of all plants and animals on Earth. However, the majority of bacteria have not yet been characterised.
Bacteria (plural of bacterium) are microscopic single-celled  organisms (prokaryotes) that reproduce by binary fission, i.e.  one cell splits into two, the two cells split i â¦ nto four, etc., etc.ne bacteria that is found in some â¦ foods is salmonella.  Other sources of bacteria are contaminated swimming pools or rivers  in which a person can swim in. These are called waterborne  diseases.
