Growth Parameters | Desulfomicrobium |
PHYSIOLOGICAL |
Tropism | Chemoorganotrophic, |
Oxygen | Strictly anaerobic, having both a respiratory and a fermentative type of metabolism. Hydrogen gas, lactate or malate is oxidized as the electron donor |
pH | optimum pH 6.6 7.5 |
Temperature | Optimum temperature, 25-40 oC |
Requirements | all species can grow on simple defined media but growth is stimulated by the addition of yeast extract. |
Products | organic substrates are incompletely oxidized to acetate, ethanol is not used |
Enzymes | |
Unique features | desulfoviridin is absent, sulfate, sulfite and thiosulfate are reduced to hydrogen sulfide. Sulfur may be reduced. |
