Background Desulfovibrio aespoeensis (strain ATCC 700646 / DSM 10631 / Aspo-2) is a halotolerant, sulfate-reducing Gram-negative bacterium isolated from granitic groundwater sampled at a depth of 600 m at Aspo hard rock laboratory, Sweden. The cells are vibrioid (0.5 pm in diameter and 1.7-2.5 pm long) and occur singly. They are motile and contain desulfoviridin. In the presence of sulfate, lactate is utilized as the sole electron donor and carbon source, but it is incompletely oxidized to acetate. D. aespoeensis grows lithoheterotrophically on H2, and acetate (as the carbon source). The electron acceptors include sulfate, thiosulfate and sulfur, but not nitrate and iron(III) hydroxide. NaCl is not required for growth, but up to 30 g/l is tolerated, and optimum growth occurs in the presence of 7 g/l. The temperature range for growth is between 4-35 degrees Celsius, with an optimum at 25-30 degrees Celsius. The optimum pH for growth is 7.5. D. aespoeensis differed from all other Desulfovibrio species (except D. longus) by its inability to utilize ethanol. (Adapted from PMID: 9542102). (EBI Integr8)
