Agar is a unique substance in that it contains much of the content of seaweed. When choosing the natural environment for such bacteria, it was clear that a piece of seaweed would be most logical place to start looking. The conditions for such bacteria are selective in the sense that not all bacteria possess the metabolic capability of decomposing agar. It is a known fact that bacterial species share a natural environment. A broad environment such as soil makes it quite difficult to isolate a specific species with simple Nutrient Agar streaking methods.
Plates creates a selective environment for their growth.
Considering that this bacterium will not use glucose as its carbon source, but will use uric acid, the conditions can be replicated and its isolation achievable. Many bacteria are unable to use uric acid as its food source. This again, creates the desirable selective environment for its isolation. As the name implies, these bacteria are capable of thriving in conditions where the salt content is unbearable for other species. In choosing to use both Mediterranean Sea Salt and a Fish Sauce, both of which are highly hypersaline in composition.
