Content: In the environment, various species (e.g. Mycoplasmas and Actinomycetes) have been shown to form endospores. While many of the species are parasitic and capable of causing diseases in animals, some of the species (e.g. Actinomycetes) are beneficial in that they produce medically relevant compounds such as antibiotics . 3D medical animation still showing Staphylococcus Bacteria by www.scientificanimations.com / CC BY-SA (https://creativecommons.org/licenses/by-sa/4.0)
Major Characteristics of Eubacteria
Metabolism
Because of the diversity of species classified under the domain Eubacteria and the fact that they are found in a wide range of habitats, they have been shown to display a higher diversity in their energetic sources and metabolic pathways when compared to eukaryotes. In the absence of organic matter, many species (described as chemoautotrophic eubacteria) have been shown to obtain their energy through the oxidization of mineral compounds. A good example of this is bacteria species that oxidize nitrates or methane. In the process, they also play an important role in converting various material into useable compounds. Using such compounds as ammonia, nitrifying bacteria produce nitrates that are used by plants to make proteins and amino acids etc. Some of the main nutritional modes of different species in the domain Eubacteria include: · Autotrophic - Produce their own food through photosynthetic processes
· Heterotrophic - Obtain nutrients from their environment (because they are unable to synthesize their own food)
· Strictly or facultatively aerobic - Survive in the presence of oxygen (strict aerobes) or can switch to anaerobic respiration in the absence of oxygen ( facultative anaerobes)
· Strictly or facultatively anaerobic - Survive in the absence of oxygen (strict anaerobes) or can survive with or without oxygen (facultative anaerobes)
For Eubacteria, diversity in the modes of metabolism is also due to the wide variety of chemical compounds that serve as substrates as well as the ability to produce energy in different environmental conditions. Whereas various photosynthetic forms require oxygen for photosynthesis, others can depend on fermentation processes for energy and only grow well in the absence of oxygen.
