| CELLULAR |
| Staining | Gram-negative |
| Morphology | Curved or occasionally straight rods, sometimes sigmoid or spirilloid, 0.5-1.5 by 2.5-10.0 um. The morphology is influenced by age and environment; descriptions refer to freshly grown cultures in anaerobic sulfate-enriched media.. |
| Motility | Motile by means of a single or lophotrichous polar flagella |
| Specialized structures | Endospores not formed. |

| Growth Parameters | Desulfovibrio |
| PHYSIOLOGICAL |
| Tropism | Chemoorganotrophic. Most
species oxidize organic compounds such as lactate
incompletely to acetate, which cannot be utilized
further. In a few cases acetate and other substrates are
oxidized completely to CO2. Strains of some species may show mixotrophic growth using H2 as the energy source and assimilating acetate + CO2, or yeast extract, as carbon sources. |
| Oxygen | Obligately anaerobic. Possess mainly a respiratory type of metabolism with sulfate or other sulfur compounds as the terminal electron acceptors, being reduced to H2S; however, the metabolism is sometimes fermentative. |
| pH | |
| Temperature | Optimum temperature, usually 25-35`C; upper limit normally 44`C; some strains can grow at temperatures at or below 0`C. A thermophilic species has been reported |
| Requirements | Media containing a reducing agent are required for growth. In a few cases a vitamin requirement has been reported. Some species and subspecies are moderately halophilic.. |
| Products | Carbohydrates are Rarely utilized. Gas is never formed from carbohydrates |
| Enzymes | Hydrogenase is usually present. Gelatin is not liquefied. Nitrates are sometimes reduced. Molecular nitrogen is sometimes fixed. |
| Unique features | . Cells contain c-type
cytochromes (c3) and usually b-type cytochromes. Many species contain desulfoviridin. Species generally show some degree of antigenic cross-reaction. |
