Description and Significance
Desulfobulbus propionicus is a sulfate-reducing, Gram-negative bacteria that does not produce spores. Its appearance is ellipsoidal and cells are roughly 1-1.3 by 1.8-2 micrometers in size. Currently there are three described strains: 1 rp 3 (designated as the type strain), 2 pr 4, and 3 pr 10. D. propionicus is described as non-motile, surrounded by pili, and lacks a flagellum. As it cannot actively propel itself, it must rely on gliding motility on solid surfaces.
Sulfate, sulfite, and thiosulfate all serve as electron acceptors, ultimately reducing to hydrogen disulfide.
The optimal pH range for D. propionicus is 7.1-7.5, but it can survive and grow between 6.0-8.6. As for temperature, it can survive between 10-43 degrees Celsius while the optimum temperature for growth is 39 degrees Celsius. These optimum conditions may vary among the other strains.
