| Description | Eubacterium siraeum is a Gram-positive, rod-shaped microbe that thrives in a temperature range of 20-40°C, classified as mesophilic. As a heterotroph, it obtains its energy from the breakdown of organic compounds, rather than via photosynthesis or chemosynthesis. This microbe is able to produce energy through a process of fermentation, where it breaks down complex molecules to derive energy. Eubacterium siraeum is widely distributed and can be found in various body sites across different species, including the human gut, skin, and oral cavity. Its ability to colonize diverse niches is likely due to its tolerance for varying environments and its capacity to adapt to different nutrient availability. The microbe shows an obligate anaerobic preference, meaning it is unable to survive in the presence of oxygen. Instead, it thrives in environments with low oxygen levels or absent oxygen. This adaptation is likely an evolutionary response to the anaerobic conditions found in certain body sites, such as the gastrointestinal tract. Eubacterium siraeum's uniqueness lies in its ability to utilize a wide range of carbon sources, including carbohydrates, proteins, and lipids. This metabolic versatility allows it to thrive in environments with varying nutrient availability. Additionally, its ability to produce various metabolic byproducts, such as short-chain fatty acids, contributes to its importance in maintaining the balance of the gut microbiota. One of the key roles Eubacterium siraeum plays in human health is its involvement in the degradation of complex nutrients, allowing for the absorption of essential nutrients. Its presence in the gut also helps maintain a healthy gut-brain axis, with studies suggesting a link between alterations in the gut microbiota and various neurological disorders. Furthermore, research has implicated Eubacterium siraeum in the development of certain human diseases, such as periodontitis and inflammatory bowel disease. Despite being a relatively understudied microbe, Eubacterium siraeum's importance in human health and disease underscores the need for further research into its biology and ecology. |
