Description and significance
Streptomyces lividans is a gram-positive, filamentous, soil bacterium. With its high G-C content, this species is known for its genomic plasticity (1). Responsible for the breakdown of organic soil material, Streptomyces are non-pathogenic bacteria that live in colonies. Because of their natural habitat, along with the non-pathogenic character of the species in the genus, S. lividans is used as hosts for the synthesis and secretion of homologous and heterologous proteins (3). Bacteria belonging to the genus Streptomyces have mycelial growth, undergoing a complex biochemical and morphological change before forming exospore chains (2). The Streptomyces lividans has been extensively studied in laboratories for possible therapeutic uses because of its abundance in multi-drug resistant genes. The Streptomyces genus is responsible for producing a majority of the antibiotics, some immunosuppressants, and anti-tumor agents used today (9).
Genome structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Does it have any plasmids? Are they important to the organism's lifestyle?
Cell structure and metabolism
Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.
Ecology
Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.
Pathology
How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
Application to Biotechnology
Does this organism produce any useful compounds or enzymes? What are they and how are they used?
