Lactococcus piscium strain DSM 6634

Lactococcus piscium strain DSM 6634 is a Gram-positive, non-motile cocci bacterium characterized by its chain arrangement. This strain is primarily associated with specific habitats, notably steak tartare and vacuum-packaged meats, suggesting a role in food-related environments. It possesses a single replicon, indicating a simple genomic structure. Lactococcus piscium is noteworthy for its lack of sporulation, which may influence its survival strategies in the microenvironments of its habitats. Additionally, this strain has been identified in association with the fish species Oncorhynchus mykiss, indicating a possible ecological relationship or host-specific interaction. The presence of flagella in Lactococcus piscium DSM 6634 has been noted, although the bacterium is described as non-motile. This may imply that while the genetic capacity for flagella exists, it does not contribute to mobility in this particular strain. The ecological role of Lactococcus piscium in the contexts of meat preservation and its interaction with specific hosts like Oncorhynchus mykiss highlights the importance of microbial communities in maintaining the quality and safety of food products. The strain's characteristics suggest potential applications in food microbiology, particularly in developing biopreservation strategies for meat products. Understanding these traits can provide insights into how Lactococcus piscium contributes to the complexity of microbial ecosystems in food and aquatic environments.
