 One specific strain of "P. stutzeri", strain RCH2, is currently being studied as a potential tool for the bioremediation of soil and water supplies since it has shown an ability to reduce hexavalent chromium concentrations in areas where this pollutant is high.Several other "P. stutzeri" strains, such as strain A15, have demonstrated an ability to reduce atmospheric nitrogen so they are being explored as agents to help increase plant growth.These strains are specifically being studied for use in rice plants because they have been shown to naturally infect and inhabit the roots of these plants.
