| Description | Desulfovibrio desulfuricans is a microorganism that thrives in a variety of environments, exhibiting a range of characteristics that enable its survival and success. It belongs to the temperature preference category of psychrophiles, tolerating temperatures between 0°C and 20°C. This microbe is a chemotroph, relying on chemical energy sources rather than light, and more specifically, it is a chemoheterotroph, as it derives its energy from the oxidation of organic compounds. Desulfovibrio desulfuricans is capable of producing energy through anaerobic respiration, using a variety of methods including sulfate reduction, iron oxidation, and sulfur reduction. The bacterium stains Gram-negative, indicating the presence of an outer membrane and a thin peptidoglycan layer. Its shape is typically bacterium-like, with a rod-like or vibrio morphology. It can be found in various body sites, including the human gut, soil, and aquatic environments. Desulfovibrio desulfuricans is an obligate anaerobe, requiring the absence of oxygen to survive, and is sensitive to even low levels of oxygen. Desulfovibrio desulfuricans has adapted to its environment through a range of strategies. Its ability to tolerate low temperatures and anaerobic conditions makes it a key player in ecosystems where these conditions prevail. Furthermore, its capacity for sulfate reduction plays a crucial role in the global sulfur cycle, alongside its role in the degradation of organic matter in anaerobic environments. This microbe's unique characteristics have also led to its use in biotechnological applications, such as the treatment of industrial waste and the production of biofuels. |
