Faecalibacterium cf. prausnitzii KLE1255

Faecalibacterium cf. prausnitzii KLE1255 is a Gram-positive, rod-shaped, non-motile bacterium that falls under the category of chemoheterotrophs, utilizing organic compounds as an energy source. This species is anaerobic, thriving in environments devoid of oxygen, which is typical for many members of the gut microbiota. Faecalibacterium cf. prausnitzii KLE1255 is mesophilic, with an optimal growth temperature of 37°C, although it can survive within a broader temperature range. The bacterium is characterized by having a single replicon and does not form spores, which may influence its survival strategies in various habitats. The presence of flagella suggests potential for movement, although the non-motile nature indicates that it does not utilize this feature for locomotion. Faecalibacterium cf. prausnitzii KLE1255 has been recognized for its ecological significance in the human gut microbiome, where it may play a role in maintaining gut health and modulating immune responses. Its ability to thrive in anaerobic conditions and its non-sporulating nature suggest that it is well-adapted to the stable environment of the gastrointestinal tract, where it can contribute to the fermentation of dietary fibers and production of beneficial short-chain fatty acids. This ecological role underscores the importance of maintaining a balanced gut microbiota for overall health.
