Phylum Proteobacteria, Class Epsilonproteobacteria, Order Campylobacterales, Family Campylobacteraceae, Genus Sulfurospirillum,
Sulfurospirillum arcachonense Finster, Liesack and Tindall 1997.
Gram-negative, curved cells 0.3 x 1-2.5 μm. Nonsporeforming. Motile by polar flagella.
Colonies in deep agar are white, round, and filamentous when grown on S. Colonies
are lens-shaped and yellowish-brown when grown with oxygen or fumarate.
Temperature range is 8-30 ºC with optimal growth at 26 ºC. Grows with 0.6-4% NaCl
and at least 0.1% MgCl2 * 6H2O is required. The pH range is 6.1 to 8.2; optimum, 7.0
to 7.4. Can grow with 1% glycerol.
Microaerobic growth occurs with up to 15% oxygen when agitated.
Formate, acetate, proprionate, succinate, alanine, fumarate, alpha-ketoglutarate,
lactate, citrate, malate, and yeast extract are oxidized with oxygen.
Isolated from oxidized surface sediment in an intertidal mud flat near Archachon, France.

Positive results for catalase, oxidase,urease and fermentation of fumarate.
Negative results for fermentation of malate and pyruvate.
