Background

Actinomycetes is a nontaxonomic term for a group of common soil microorganisms sometimes called "thread or ray bacteria." Actinomycetes are a versatile group of Gram-positive, rod shaped and spore forming bacteria widely distributed in the terrestrial and aquatic environments [6]. The specialty of the actinomycetes is that they have a mycelial appearance unlike most bacteria. Since the cultivation and maintenance of actinobacteria are not that easy as in the case of other bacteria, they are rather underexplored. Actinomycetes are prokaryotic organisms that are classified as bacteria, but are unique enough to be discussed as an individual group.

Actinomycetes play an key role in the break down of various organic materials in soil as well as their ability to produce a range of bioactive molecules, including antibiotics and various kinds of enzymes.

Another significance of these bacteria is that from the rhizosphere, they suppress the growth of pathogens.
