Caldanaerobacter subterraneus strain DSM 13054

Caldanaerobacter subterraneus strain DSM 13054 is a thermophilic, anaerobic bacterium classified as a chemoheterotroph, indicating that it derives energy from organic compounds while not relying on light or inorganic substrates. This strain is non-motile, lacking the capacity for movement, despite possessing flagella, which may play a role in its interaction with the environment rather than in mobility. The strain is characterized by a single replicon, which is typical for many bacterial species and suggests a streamlined genetic organization. Notably, Caldanaerobacter subterraneus is nonsporulating, indicating that it does not form spores as a means of survival under adverse conditions, which can be a common trait among certain anaerobic microorganisms. The habitat of Caldanaerobacter subterraneus is classified as multiple, suggesting that this bacterium can thrive in various anaerobic environments, likely including those rich in organic materials, such as sediments in lakes or the intestines of animals. The ecological role of Caldanaerobacter subterraneus may involve contributing to the breakdown of complex organic matter in anaerobic environments, thus playing a significant part in nutrient cycling within its habitats. Understanding the specific interactions and contributions of this strain in its ecological niche could provide insights into the dynamics of anaerobic microbial communities and their overall impact on biogeochemical processes.
