Denitrovibrio acetiphilus DSM 12809

Denitrovibrio acetiphilus (strain DSM 12809 / N2460) is an obligatory anaerobic, dissimilatory nitrate-reducing Gram-negative bacterium isolated from an oil reservoir modeling column under nitrate enrichment in Norway. The cells are vibrio shaped and motile by a bipolar flagellum. D. acetiphilus grows well on acetate with nitrate as electron acceptor, producing ammonia. The presence of a 2-oxoglutarate dehydrogenase activity indicates that acetate is oxidized via the citric acid cycle. It grows at temperatures between 4 and 40 degrees Celsius and at a pH between 6.5 and 8.6. The optimum temperature is 35-37 degrees Celsius and no growth is obtained at 45 degrees Celsius. NaCl is not required for growth and D.acetiphilus grows well in medium containing up to 6% NaCl. (adapted from PMID: 10939668). (EBI Integr8)
