 While the bacterium has been shown to grow on solid media (such as gelatin and agar), liquid media (such as nitrate or nitrite-free media), and even potatoes, it shows optimal growth on peptone or yeast agar.When in aerobic environments, "P. stutzeri" can even grow on more complex media such as lysogeny and Reasoner's 2A (R2A) broths, with the latter of the two being significantly useful in selecting for specific microbes due to its lack of abundant nutrients.Each of the assorted media produce their own slight variations in the phenotypes of the "P. stutzeri" colonies that result from growth.
