Description and significance
Describe the appearance, habitat, etc. of the organism, and why it is important enough to have its genome sequenced. Describe how and where it was isolated. Include a picture or two (with sources) if you can find them.
A gram-negative rod shape bacterium that produces violet pigment - hence the name violaceum - when grown in tryptic soy broth (Chen et al, 2002).
Usually found in tropical and subtropical regions with temperature around 20°C-37°C as its optimal temperature; and growth would be inhibited with temperature near or below 4°C (chen et al, 2002).
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.
Chromobacteria do not usually cause diseases in humans, the first C. violaceum infection reported was in 1927 from Malaysia, and approximately 150 cases reported worldwide, such as Asia, USA, Australia, and Africa (Martinez & Mattar, 2007).
Application to Biotechnology
Does this organism produce any useful compounds or enzymes? What are they and how are they used?
