Corynebacterium glutamicum strain ATCC 13869

Corynebacterium glutamicum strain ATCC 13869 is a Gram-positive, non-pathogenic bacterium characterized as a chemoorganotroph, meaning it derives energy from organic compounds. This strain exhibits a rod shape and is non-motile, lacking flagella despite the presence of a flagellar structure. It has a single replicon, indicating a streamlined genetic architecture. C. glutamicum is facultatively anaerobic, allowing it to thrive in both oxygen-rich and low-oxygen environments. It is classified as mesophilic, with an optimal growth temperature of 30°C, which reflects its adaptability to moderate environmental conditions. The strain does not undergo sporulation, which is a characteristic feature of some bacteria that allows them to survive extreme conditions. Instead, C. glutamicum maintains a free-living biotic relationship, indicating that it does not rely on a host organism for survival. The ecological significance of C. glutamicum lies in its role in various biotechnological applications, particularly in the fermentation industry. Due to its non-pathogenic nature and ability to metabolize organic substrates efficiently, it is often employed in the production of amino acids, such as L-glutamate and L-lysine. This bacterium’s metabolic versatility and safety profile make it a valuable organism in both laboratory and industrial settings. The comprehensive genome information, available under accession NZ_CP016335.1, further supports its application in microbial biotechnology, highlighting the importance of understanding its physiological traits for potential advancements in microbial utilization.
