Streptomyces

Streptomyces is a genus of Gram-positive bacteria that belongs to the phylum Actinobacteria. It is the largest genus of Actinobacteria, with over 500 species worldwide. Streptomyces is renowned for its ability to produce a wide range of secondary metabolites, including many antibiotics, antifungals, and antiparasitics.

Characteristics

Streptomyces are aerobic, spore-forming bacteria that are found in soil and decaying vegetation. They are characterized by a complex secondary metabolism and produce over two-thirds of the clinically useful antibiotics of natural origin.

Metabolism

Streptomyces are capable of metabolizing a wide range of organic compounds. They are known for their ability to produce a variety of secondary metabolites, including antibiotics, antifungals, antiparasitics, and other bioactive compounds.

Antibiotic production

Streptomyces is the largest antibiotic-producing genus, with over 500 species producing potent antibiotics. The antibiotics produced by Streptomyces include streptomycin, neomycin, and chloramphenicol.

Genomics

The genomes of several Streptomyces species have been sequenced, providing valuable insights into their complex secondary metabolism and their ability to adapt to diverse environments.
