Chromobacterium violaceum
''Chromobacterium violaceum'' is a Gram-negative, facultative anaerobic, non-sporing coccobacillus.It is motile with the help of a single flagellum which is located at the pole of the coccobacillus. Usually there are one or two more lateral flagella too. It is part of the normal flora of water and soil of tropical and sub-tropical regions of the world. It produces a natural antibiotic called violacein, which may be useful for the treatment of colon and other cancers. It grows readily on nutrient agar, producing distinctive smooth low convex colonies with a dark violet metallic sheen (due to violacein production). Some strains of the bacteria which do not produce this pigment have also been reported. It has the ability to break down tarballs.
==Biochemistry==
''C. violaceum'' ferments glucose, trehalose, ''N''-acetylglucosamine and gluconate but not L-arabinose, D-galactose, or D-maltose.It is positive for catalase and oxidase reactions.〔 Bacterial isolates in many cases can show high level resistance to a range of antibiotics.
