Microbe Identification
Microbe nameBacillus cereus
NCBI Taxonomy ID1396
DescriptionEubacterium limosum is a Gram-positive, rod-shaped microbe that thrives in mesophilic temperatures, categorizing it as a chemoheterotroph, and can be found in various body sites, including the gut, oral cavity, and skin, across different species. As an obligate anaerobe, Eubacterium limosum requires the absence of oxygen to survive and grow, which is reflected in its inability to produce superoxide dismutase, an enzyme that protects against oxidative stress. The Gram-positive characteristic is due to the presence of a thick peptidoglycan layer in its cell wall, which retains the crystal violet stain during the Gram staining procedure. Its rod shape is typical of many bacteria, allowing for efficient movement and nutrient uptake. As a chemoheterotroph, Eubacterium limosum relies on organic compounds for energy and carbon, breaking down complex molecules into simpler ones for sustenance. The presence of Eubacterium limosum in different body sites suggests its ability to adapt to various environments and host-microbe interactions. In the human gut, for example, Eubacterium limosum plays a role in the degradation of complex polysaccharides, contributing to the production of short-chain fatty acids. Eubacterium limosum has been implicated in the production of butyrate, a short-chain fatty acid with anti-inflammatory properties, which may have potential applications in the development of therapeutic strategies for inflammatory bowel diseases.
