Listeria monocytogenes 21

Listeria monocytogenes 21 is a Gram-positive, rod-shaped bacterium classified as a chemoorganotroph, indicating it derives energy from organic compounds. This organism exhibits a distinctive cell arrangement, often found in chains or as singles. It is a facultative anaerobe, which means it can grow in both aerobic and anaerobic environments, demonstrating versatility in its oxygen requirements. This species does not exhibit mobility, yet it possesses flagella, which may play a role in its life cycle under certain conditions. Listeria monocytogenes 21 thrives optimally at a temperature of 30°C, fitting within a mesophilic temperature range. It is notable for having three replicons, which may contribute to its genetic diversity and adaptability. In terms of its ecological role, Listeria monocytogenes 21 is free-living, suggesting it can survive independently in various environments. This trait, combined with its ability to utilize a range of organic substrates, facilitates its persistence in diverse habitats. The organism's adaptability to different oxygen levels and temperatures may also enhance its survival in fluctuating environmental conditions, potentially impacting food safety and public health. Understanding these characteristics is essential for managing the risks associated with Listeria monocytogenes 21 in food products and the environment. The accessions for this bacterium include FR733643.1, CP013288.1, and CP039751.1, which provide further genomic information for research and study.
