Desulfohalobium retbaense DSM 5692

Names Desulfohalobium retbaense DSM 5692
Accession numbers NC_013223, NC_013224
Background Desulfohalobium retbaense (strain DSM 5692) is an anaerobic, moderately halophilic sulfate-reducing Gram-negative bacterium isolated from sediment of the pink hypersaline Lake Retba in Senegal, Africa. This organism incompletely oxidizes ethanol, pyruvate, and lactate to acetate and CO(2). Sulfate, sulfite, thiosulfate, and elemental sulfur are used as electron acceptors and reduced to H2S. Growth occurs at pH values ranging from 5.5 to 8.0, with an optimum pH between 6.5-7.0. The optimum temperature for growth is between 37 to 4O degrees Celsius, and 45 degrees Celsius is the upper temperature limit for growth. NaCl and MgCl(2), are required for growth, with an optimum NaCl concentration near 10%. (Adaptated from: (EBI Integr8)
