Background Desulfobacterium autotrophicum (strain ATCC 43914 / DSM 3382 / HRM2) is a anaerobic sulfate-reducing bacterium isolated from a marine sediment in the Mediterranean sea near Venice, Italy. D. autotrophicum plays an important role in the ecology of marine sediments. It is involved in the anaerobic mineralization of organic matter coming from the water column. The metabolic versatility of D. autotrophicum is reflected in the presence of genes for the degradation of a variety of organic compounds including long-chain fatty acids and for the Wood-Ljungdahl pathway, which enables the organism to completely oxidize acetyl-CoA to CO2 but also to grow chemolithoautotrophically. D. autotrophicum is capable of growing litho-autotrophically with H2, CO2 and sulfate, but also by coupling sulfate reduction with the oxidation of fatty acids. CO2 fixation proceeds via the acetyl-CoA/CO-dehydrogenase pathway. This organism can transform tetra to dichlormethane.The presence of more than 250 proteins of the sensory/regulatory protein families should enable D. autotrophicum to efficiently adapt to changing environmental conditions.
