Question

Nitrifying Bacteria vs. Archaebacteria vs. Eubacteria?

Answer 1

Nitrifying bacteria

any of a small group of aerobic bacteria (family Nitrobacteraceae) that use inorganic chemicals as an energy source. They are microorganisms that are important in the nitrogen cycle as converters of soil ammonia to nitrates, compounds usable by plants. The nitrification process requires the mediation of two distinct groups: bacteria that convert ammonia to nitrites (Nitrosomonas, Nitrosospira, Nitrosococcus, and Nitrosolobus) and bacteria that convert nitrites (toxic to plants) to nitrates (Nitrobacter, Nitrospina, and Nitrococcus).

Archaebacteria are the oldest living organisms on earth. They are prokaryotes and unicellular. Archaebacteria are found in very harsh conditions (such as at the bottom of the sea or in volcanic vents). This is thought to be because the early Earth’s atmosphere was filled with poisonous gases and was very hot – nothing could survive, except the archaebacteria. These slowly gave way to modern organisms when the Earth’s conditions settled down and oxygen was introduced to the atmosphere.

Archaebacteria are difficult to classify because they have similarities to both normal bacteria and the larger eukaryotes. In structure, they are like unicellular prokaryotes, but the genetic transcription and translation underlying their creation is similar to that of the more complex eukaryotes

The eubacteria are more complex, and common, than the archaebacteria. It is the eubacteria that most people are talking about when they say bacteria, because they live in more neutral conditions. They can be found everywhere around us – in our bodies, our food, etc. There are four phyla of bacteria, some of which are divided into subgroups.

Unlike the Archaea, the Eubacteria have been known and studied for more than 150 years.

Eubacteria differ from the Archaea in the form and structure of their ribosomes, the type and linkage of their lipids, the structure of their cell covering, and the type of RNA polymerase .
