- Scientific Context:
- Many commercially important antibiotics are derived from Streptomyces.
- The Streptomyces genome contains a high number of genes dedicated to the production of secondary metabolites.
- Taxonomic Reference: The word is capitalized () when referring to the formal genus name in biological taxonomy. The plural form is (often not capitalized in general text) when referring to multiple types or species within this group.
