Kingdom Eubacteria

Description-Eubacteria are a group of tiny, single celled prokaryotic organisms, found in every habitat on earth. They recycle many of the nutrients found in the earth’s soil, and also play an important part in nitrogen fixation. Their sheer quantity forms a great deal of the world’s biomass. Eubacteria can negatively affect animals and plants, but the immunes systems of these organisms typically prevent them from doing harm.

Body Plan-Eubacteria are unicellular

Divergent Event-Eubacteria and archaebacteria, due to their structural similarities, defy many attempts to identify exactly when they diverged from each other and became distinct types of prokaryotes. Research into genetic sequencing suggests that the split occurred about 3 billion years ago, and that eubacteria diverged first from archaebacteria, which were their predecessors.

Metabolism -There are both autotrophic and heterotrophic Eubacteria. Some Eubacteria receive energy from the sun, while others engulf organic compounds in their environment. An example of autotrophic Eubacteria is Chloroflexi, while an example of heterotrophic Eubacteria is Bacillus.

Digestion-Eubacterial digestion is intracellular: Eubacteria engulf their nutrients and digest them within their cell membranes

Circulation-Eubacteria possess no circulatory system

Respiration-Eubacteria possess no respiratory system

Nervous System-Eubacteria possess no nervous system

Reproduction-Eubacterial reproduction is asexual reproduction. Most Eubacteria perform binary division to reproduce, splitting their nuclei into two.

Examples: Myxococcus xanthus, a predatory Eubacterium that swarms other bacteria to kill and digest them.

Lactobacillus, a type of Eubacteria which converts proteins found in milk into lactic acid, and lives benignly inside the human body.
