| Description | Eubacterium saphenum is a Gram-positive, rod-shaped microbe that thrives in a temperature range of mesophilic to thermophilic, preferring temperatures between 25°C to 55°C. It is a chemoheterotroph, utilizing organic compounds as its energy source and carbon source. E. saphenum produces energy through the process of fermentation, breaking down complex molecules into simpler compounds and releasing energy in the form of ATP. As a human gut commensal, E. saphenum can be found in the oral cavity, upper respiratory tract, and gastrointestinal tract of various mammalian species, including humans. In the gut, it plays a crucial role in the breakdown and release of dietary fiber, contributing to the synthesis of short-chain fatty acids, which are important energy sources for the host. E. saphenum is an obligate aerobe, requiring oxygen to survive and grow. It has a remarkable ability to tolerate high concentrations of oxygen, typical of microaerophiles. This characteristic allows it to thrive in environments where oxygen availability is limited, such as the human gut. In terms of its nutritional requirements, E. saphenum is capable of utilizing a wide range of organic compounds, including carbohydrates, proteins, and lipids. It has also been shown to play a role in the synthesis of vitamins, including vitamin K and folate, which are essential for human health. Eubacterium saphenum has been linked to various human diseases, including dental caries, periodontitis, and inflammatory bowel disease. However, its role in these processes is still being researched and debated. Despite this, E. saphenum remains an important member of the human microbiome, highlighting the complex and dynamic relationships between microorganisms and their hosts. |
