Actinomycetota

Actinomycetota is a phylum of the domain Bacteria, and represents one of the largest bacterial phyla. It is composed of Gram-positive bacteria that are characterized by a high G+C content. They are known for their ability to produce a wide range of bioactive compounds, including antibiotics.

Characteristics

Members of the Actinomycetota phylum are generally Gram-positive, although some can stain Gram-negative. They are characterized by a high G+C content in their DNA, typically above 55%. Many species form branching filaments, similar to the mycelium of fungi, and can form complex structures such as spores and fruiting bodies.

Ecology

Actinomycetota are found in a wide range of habitats, including soil, water, and the human body. They play important roles in the decomposition of organic materials, contributing to the carbon cycle and soil fertility. Some species are pathogenic to humans and other animals.

Economic importance

Many species of Actinomycetota are of economic importance due to their ability to produce bioactive compounds. These include antibiotics, such as streptomycin and tetracycline, as well as other drugs and biotechnologically useful enzymes.

Classification

The phylum Actinomycetota is divided into several classes, including Actinobacteria, Acidimicrobiia, Coriobacteriia, and Rubrobacteria. These are further divided into orders, families, genera, and species.
