The Desulfobacteraceae form a family within the Deltaproteobacteria . Like all families of order desulfobacterales they are able sulfate to reduce ( sulfate-reducing bacteria ). The sulphate reduction generates energy, which is then converted into further metabolism. Hydrogen sulfide (H 2 S) is excreted as the end product . This is also referred to as sulfate respiration.
Way of life
Most types of sulfate-reducing bacteria are obligatorily anaerobic ; they can only live in the absence of oxygen. Such conditions prevail e.g. B. within the muddy bottoms of lakes or in submerged soils. Some (e.g. species of the genus Desulfobacterium ) are chemolithotrophic , they are able to feed exclusively on inorganic substances with hydrogen as an electron donor . They use carbon dioxide as a source of carbon . Some species only occur in seawater (e.g. Desulfobacterium ).
morphology
The cell shape is different for the various classes, there are filamentous (filamentous) forms (eg. In Desulfonema ) but also rod-shaped ( Desulfobakterium ) or coccoid cells are juxtaposed the package type, called sarcinse ( Desulfosarcina ). Some species have flagella (for example Desulfobacter ).
