Pedomicrobium americanum sp. nov. and Pedomicrobium australicum sp. nov. from Aquatic Habitats, Pedomicrobium gen. emend., and Pedomicrobium ferrugineum sp. emend. †

Five new strains of budding bacteria of the genus Pedomicrobium were isolated from freshwater habitats. These strains formed two groups, both of which fitted the description of the genus Pedomicrobium, but their characteristics did not match the description of any existing species. Pedomicrobium americanum is proposed for strains IFAM G-1381 (= ATCC 43612), IFAM BA-868 (= ATCC 43613), and IFAM BA-869 (= ATCC 43615), with strain IFAM G-1381 as the type strain. Strains IFAM ST-1306 (= ATCC 43611) and IFAM WD-1355 (= 43614) are named Pedomicrobium australicum, with strain IFAM ST-1306 as the type strain. The descriptions of the genus Pedomicrobium and of the type species Pedomicrobium ferrugineum are emended.
