 There is also evidence of "P. stutzeri" in wastewater treatment plants.ZoBell, AN10, NF13, MT-1, and HTA208 are the most significant strains isolated from marine environments and have been found in places such as water columns in the Pacific-ocean, polluted Mediterranean marine sediments, Galapagos rifts near hydrothermal vent at depths of 2500 meters, and Mariana trench samples at 11 000 meters.Several other "P. stutzeri" strains have even been found in other locations such as manure, pond water, straw and humus samples.
