Description and Significance
Carnobacterium are rod-shaped lactic acid bacteria. They thrive in Identifying Carnobacterium is easiest using 16S-23S rDNA ISRs that gives species specific primers that are helpful in distinguishing all eight of the Carnobacterium species. A. The presence of Carnobacterium can be found in seawater as well as dairy, fish, & meat products. They can also be found in polar regions and cold environments. Carnobacterium include the psycrophilic anaerobic species C. maltaromaticum, C. divergens & C. pleistocenium. Certain species have preservative qualities of meat products. Some are also attributed to meat spoilage. C. pleistocenium has been found in a permafrost tunnel in Fox, Alaska. The ice dates back to the Pleistocene Epoch (1.8 Ma to 11,000 years ago).
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces. C. divergens & C. maltaromaticum have properties that make them preservative-like. Several strains of C. maltaromaticum have been FDA approved to be used as a preservative in processed, ready to eat meat products.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
