| Description | Eubacterium eligens is a gram-positive, rod-shaped bacterium that thrives in a temperature range of 25-37°C, classified as mesophiles. This bacterium is a chemoheterotroph, meaning it obtains its energy by breaking down organic compounds in the absence of light. Specifically, it utilizes fatty acids and other organic acids as its primary energy source. Eubacterium eligens produces energy through the process of fermentation, converting glucose into lactic acid. This microbe is widely distributed and can be found in various body sites, including the oral cavity, gastrointestinal tract, and female genital tract, of humans and other animals. Its ability to colonize these diverse environments is likely due to its adaptability and tolerance for varying pH levels and oxygen conditions. Eubacterium eligens is an obligate anaerobe, meaning it cannot survive in the presence of oxygen and instead thrives in environments with low or no oxygen levels. This characteristic is likely a result of its adaptations to compete with other microorganisms and thrive in environments where oxygen availability is limited. Eubacterium eligens has been associated with various human diseases, including periodontitis, dental caries, and infections of the female genital tract. In addition, its ability to degrade organic matter and produce volatile fatty acids makes it a key player in the gut microbiome, contributing to the proper functioning of the digestive system. Despite its pathogenic potential, Eubacterium eligens plays a crucial role in the ecosystem, breaking down complex organic matter and recycling nutrients. |
