 In 1998, Metcalf and Wolfe enriched for and isolated a "P. stutzeri" strain WM88 that could oxidize reduced phosphorus compounds, such as phosphite and hypophosphite, to phosphate.To enrich for a hypophosphite-utilizing organism, a 0.4% glucose-MOPS medium containing 0.5 mM hypophosphite was used as the sole phosphorus source with inoculum from a variety of soil and water environments.Specifically, strain WM88 can use phosphite as its sole phosphorus source when grown in succinate-MOPS medium.
