 While most "Pseudomonas" strains that have been isolated from marine environments are eventually transferred to another genus after classification, "P. stutzeri" is one of the few strains that has not.This strain meets the requirements of being able to tolerate NaCl and it is found in water columns in the Pacific Ocean and sediments in the Mediterranean.These marine strains have many ecological roles including naphthalene degradation, sulfur oxidation, and most importantly denitrification and diazotrophy (nitrogen fixation).
