Desulfobacca acetoxidans DSM 11109

Desulfobacca acetoxidans (strain ATCC 700848 / DSM 11109 / ASRB2) is an anaerobic, mesophilic, sulfate reducer, Gram-negative bacterium isolated from granular sludge of a laboratory-scale upflow anaerobic sludge bed reactor fed with acetate (as sole carbon and energy source) and sulfate. The bacterium is oval-shaped, 1.3 x 1.9-2.2 microns.The optimum growth with acetate occurs around 37 degrees Celsius in freshwater medium. Enzyme studies indicates that acetate is oxidized via the carbon monoxide dehydrogenase pathway. Growth is not supported by other organic acids, such as propionate, butyrate or lactate, alcohols such as ethanol or propanol, and hydrogen or formate. Sulfite and thiosulfate are also used as electron acceptors, but sulfur and nitrate are not reduced. Sulfate-reducing bacteria play an important role in the degradation of organic matter in anaerobic bioreactors treating sulfate-rich wastewaters, such as those from paper mills, tanneries or food oil industry.
