Energetic metabolism of Chromobacterium violaceum

Genet Mol Res. 2004 Mar 31;3(1):162-6.

Abstract

Chromobacterium violaceum is a free-living microorganism, normally exposed to diverse environmental conditions; it has a versatile energy-generating metabolism. This bacterium is capable of exploiting a wide range of energy resources by using appropriate oxidases and reductases. This allows C. violaceum to live in both aerobic and anaerobic conditions. In aerobic conditions, C. violaceum is able to grow in a minimal medium with simple sugars, such as glucose, fructose, galactose, and ribose; both Embden-Meyerhoff, tricarboxylic acid and glyoxylate cycles are used. The respiratory chain supplies energy, as well as substrates for other metabolic pathways. Under anaerobic conditions, C. violaceum metabolizes glucose, producing acetic and formic acid, but not lactic acid or ethanol. C. violaceum is also able to use amino acids and lipids as an energy supply.
