Streptomyces is the largest genus of Actinomycetota and the type genus of the family Streptomycetaceae. Over 500 species of Streptomyces bacteria have been described. As with the other Actinomycetota, streptomycetes are gram-positive, and have genomes with high GC content. Found predominantly in soil and decaying vegetation, most streptomycetes produce spores, and are noted for their distinct "earthy" odor that results from production of a volatile metabolite, geosmin.
Streptomyces griseus is a species of bacteria in the genus Streptomyces commonly found in soil. A few strains have been also reported from deep-sea sediments. It is a Gram-positive bacterium with high GC content. Along with most other streptomycetes, S. griseus strains are well known producers of antibiotics and other such commercially significant secondary metabolites. These strains are known to be producers of 32 different structural types of bioactive compounds. Streptomycin, the first antibiotic ever reported from a bacterium, comes from strains of S. griseus. Recently, the whole genome sequence of one of its strains had been completed.

Rhodococcus marinonascens is a bacterium species in the genus Rhodococcus. It is moderately halophilic and psychrotrophic, with type strain 3438W.
Streptomyces antibioticus is a gram-positive bacterium discovered in 1941 by Nobel-prize-winner Selman Waksman and H. Boyd Woodruff. Its name is derived from the Greek "strepto-" meaning "twisted", alluding to this genus' chain-like spore production, and "antibioticus", referring to this species' extensive antibiotic production. Upon its first characterization, it was noted that S. antibioticus produces a distinct soil odor.
Sphaerisporangium melleum is an actinomycete species of bacteria first isolated from sandy soil. It produces branching substrate mycelia and spherical spore vesicles on aerial hyphae that contain non-motile spores. They also contained diaminopimelic acid and the N-acetyl type of peptidoglycan. Its type strain is 3-28(8)T.
Sphaerisporangium rubeum is an actinomycete species of bacteria first isolated from sandy soil.

Its type strain is 3D-72(35)T.
Sphaerisporangium cinnabarinum is an actinomycete species of bacteria first isolated from sandy soil.
