All strains listed were isolated from water collected from Lake Matano, Indonesia, as described previously (38). The ability to use methylphosphonate (MPn) or 2-aminoethylphosphonate (2-AEP) was assessed by monitoring growth in NBRIP medium with MPn or 2-AEP supplied as the sole phosphorus source at a concentration of 0.2 mM. The 2-AEP results were originally reported in reference 38.
