The Actinomycetota (or Actinobacteria) are a diverse phylum of Gram-positive bacteria with high GC content. [4] They can be terrestrial or aquatic. [5] They are of great importance to land flora because of their contributions to soil systems. In soil they help to decompose the organic matter of dead organisms so the molecules can be taken up ...
Actinomyces is a genus of the Actinomycetia class of bacteria.They all are Gram-positive and facultatively anaerobic, growing best under anaerobic conditions. [2] Actinomyces species may form endospores, and while individual bacteria are rod-shaped, Actinomyces colonies form fungus-like branched networks of hyphae. [3]
Actinomycetales are generally gram-positive and anaerobic and have mycelia in a filamentous and branching growth pattern. Some actinomycetes can form rod- or coccoid-shaped forms, while others can form spores on aerial hyphae. Actinomycetales bacteria can be infected by bacteriophages, which are called actinophages. Actinomycetales can range ...
Frankia is a gram-positive Bacteria that is found on the roots of plants. The fact that Frankia is gram-positive means that the bacteria is made up of thick cell walls made out of protein called peptidologlycan. This helps with the resistance of the heavy metals that may be in the degraded soil.
The Coriobacteriia are a class of Gram-positive bacteria within the Actinomycetota phylum. [ 3 ] [ 4 ] Species within this group are non sporulating , strict or facultative anaerobes that are capable of thriving in a diverse set of ecological niches.
Scotobacteria (non-photosynthetic, now the Proteobacteria and other gram-negative nonphotosynthetic phyla) Firmacutes [sic] (gram-positive, subsequently corrected to Firmicutes [43]) several orders such as Bacillales and Actinomycetales (now in the phylum Actinobacteria) Mollicutes (gram variable, e.g. Mycoplasma)
Mycobacterium is a genus of over 190 species in the phylum Actinomycetota, assigned its own family, Mycobacteriaceae.This genus includes pathogens known to cause serious diseases in mammals, including tuberculosis (M. tuberculosis) and leprosy in humans.
