Content: Whereas some of the species in this group are capable of photosynthesis (photosynthetic Eubacteria), a majority are chemoheterotrophs and thus obtain nutrients from their surroundings. Being Gram-positive bacteria, these species retain the primary color (Crystal violet dye) during Gram staining and thus appear violet in color when viewed under the microscope. This is because they contain a thick peptidoglycan layer compared to Gram-negative species. They vary in morphology from cocci species that are spherical in shape (e.g. Staphylococcus) to rod-like species (bacilli) such as Listeria . Depending on the specie, Gram-positive bacteria can be found in different types of aquatic (marine and freshwater) and terrestrial environments. 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.
