Actinomycetes are microorganisms native to the sea and can be found on the surface of seawater, the seabed, in sediments, coral reefs, and in soil. Actinomycetes are prokaryotic, like bacteria, but possess mycelium and are classified as microbes with the potential to produce secondary metabolites. Actinomycetes form symbiotic relationships with sponges on the outside of the body (extracellular exosymbiosis), inside the sponge (extracellular endosymbiosis), in the cytoplasm (intracellular symbiosis), and in the cell nucleus (intranuclear symbiosis). Actinomycetes are capable of producing bioactive compounds from antibiotics (70%), fungi (20%), and bacteria (10%). This type of microbe has been widely used in the pharmaceutical, animal feed, fisheries, and other industries. Commercial products that utilize actinomycete secondary metabolites include tetracycline, erythromycin, vancomycin, and streptomycin.
