| Description | Desulfovibrio magneticus is a Gram-negative, spiral-shaped microbe that thrives in mesophilic temperatures, categorized as a Chemoheterotroph, and can be found in various body sites, including the gastrointestinal tract, oral cavity, and skin, across different species. As an Obligate Anaerobe, it requires the absence of oxygen to survive and grows optimally in environments with low redox potentials. The Gram-negative cell wall of Desulfovibrio magneticus is composed of a thin peptidoglycan layer and an outer membrane containing lipopolysaccharides, which provides protection against environmental stresses. Its spiral shape allows for efficient motility and navigation through dense environments. The mesophilic temperature preference of this microbe enables it to thrive in temperatures ranging from 20-40°C, making it well-suited for growth in various ecological niches. As a Chemoheterotroph, Desulfovibrio magneticus relies on the degradation of organic compounds to obtain energy, using sulfate as a terminal electron acceptor. This process involves the reduction of sulfate to hydrogen sulfide, which is a key characteristic of this microbe. The ability of Desulfovibrio magneticus to inhabit different body sites across various species highlights its adaptability and versatility. Desulfovibrio magneticus has been found to produce magnetosomes, which are membrane-bound organelles containing magnetite crystals, allowing the microbe to orient itself along magnetic fields. This unique feature enables the microbe to navigate through sedimentary environments and locate optimal growth conditions, making it a fascinating subject for further research in the fields of microbiology and geobiology. |
