Growth Parameters

Desulfobacter

PHYSIOLOGICAL

Tropism	Chemoorgano- trophic, using acetate or other simple organic compounds as carbon sources and also as electron donors for anaerobic respiration; these compounds are completely oxidized to CO2.
Oxygen	Strictly anaerobic, having a respiratory type of metabolism with sulfate or other oxidized sulfur compounds serving as terminal electron acceptors and being reduced to H2S.
pH
Temperature	Optimum growth temperature, 28-32`C
Requirements	Media containing a reductant and vitamins are necessary for growth. Most strains require at least 0.5% NaCl and 0.1% MgCl 6H2O.

Enzymes
Unique features

ENVIRONMENTAL

Habitat	Occur in the anaerobic parts of brackish water and marine habitats; have also been enriched from freshwater mud by use of salt water media.
