Desulfuromonas acetoxidans is a species of bacteria. It is strictly anaerobic, rod-shaped, laterally flagellated and Gram-negative . It is unable to ferment organic substances; it obtains energy for growth by anaerobic sulfur respiration .
This process can be carried out by both sulfate reducing bacteria and sulfur reducing bacteria. Although they thrive in the same habitats, sulfur reducing bacteria are incapable of sulfate reduction. Bacteria like Desulfuromonas acetoxidans are able to reduce sulfur at the cost of acetate. Some iron reducing bacteria reduce sulfur to generate ATP.

What can be gathered from this information is that AprBA of Desulfobacca acetoxidans is closely related to the AprBA sequences of green sulfur bacteria and the AprBA of Desulfomonile tiedjei resembles the gram-positive type. Both genomes of these families contain single copies of the dissimilatory adenylyl sulfate reductase (AprBA) linked to ...
Desulfurella acetivorans is a thermophilic acetate-oxidizing sulfur-reducing eubacterium. It ... activation in Desulfurella acetivorans and Desulfuromonas acetoxidans".
Most of the sulfur oxidizers are autotrophs that can use reduced sulfur species as electron donors for CO 2 fixation. The microbial oxidation of sulfur is an important link in the biogeochemical cycling of sulfur in environments hosting both abundant reduced sulfur species and low concentrations of oxygen, such as marine sediments, oxygen ...
Desulfotomaculum is a genus of Gram-positive, obligately anaerobic soil bacteria. A type of sulfate-reducing bacteria, Desulfotomaculum can cause food spoilage in poorly processed canned foods.
A 2016 study of the genomes of a set of bacteria and archaea suggested that the last universal common ancestor (LUCA) of all cells was using an ancient Wood–Ljungdahl pathway in a hydrothermal setting, [11] but more recent work challenges this conclusion as they argued that the previous study had "undersampled protein families, resulting in incomplete phylogenetic trees which do not reflect ...
