Gemmobacter caeni strain DSM 21823

Gemmobacter caeni strain DSM 21823 is characterized as a Gram-negative, rod-shaped bacterium with a facultative aerobe/anaerobe oxygen requirement. This strain demonstrates mesophilic growth, with an optimal temperature of 32°C. It is notable for being non-motile and non-spore-forming, features that may influence its ecological interactions and survival strategies in various environments. The strain possesses a single replicon, indicating a simpler genetic organization compared to organisms with multiple replicons. This genetic structure may affect its adaptability and evolutionary processes. The absence of sporulation suggests that Gemmobacter caeni may rely on other mechanisms for survival under adverse conditions, potentially making it more susceptible to environmental stresses compared to spore-forming bacteria. In terms of ecological significance, the facultative lifestyle of Gemmobacter caeni allows it to thrive in diverse environments, whether in the presence or absence of oxygen. Such versatility may enable this bacterium to play a role in various biogeochemical cycles, particularly in sedimentary environments where oxygen levels fluctuate. Overall, the traits of Gemmobacter caeni strain DSM 21823 highlight its adaptability and potential ecological roles, particularly in anaerobic or low-oxygen habitats, where its metabolic capabilities could contribute to nutrient cycling and ecosystem dynamics.
