Lacticaseibacillus casei 21/1

Lacticaseibacillus casei 21/1 is a mesophilic, Gram-positive bacterium characterized by its rod-shaped morphology and the arrangement of cells in chains. This organism is classified as a facultative anaerobe, indicating its ability to thrive in both the presence and absence of oxygen. It does not exhibit mobility, as it lacks flagella, and it has a single membrane surrounding its cell structure. The optimal growth temperature for Lacticaseibacillus casei 21/1 is 30°C, which falls within its mesophilic temperature range. The bacterium is free-living, suggesting that it does not rely on a host for survival and can occupy specialized habitats. The presence of a single replicon indicates a streamlined genetic organization, which may contribute to its adaptability in various environments. The accession number for this strain is AFYK00000000.1, which provides a reference for genomic studies and further research into its characteristics. From an ecological perspective, Lacticaseibacillus casei 21/1 plays a role in its specialized habitats, potentially contributing to the fermentation processes common in various ecosystems. Its ability to survive in fluctuating oxygen levels and specific temperature ranges may enable it to be a significant player in microbial communities, influencing nutrient cycling and interactions with other microorganisms.
