General Information: Country: USA; Environment: Sludge, Fresh water; Isolation: Industrial sludge contaminated; Temp: Mesophile; Temp: 30C. Pseudonocardia members are abundant in diverse environments, and are known to degrade a variety of pollutants. These bacteria are also important in biocatalysis applications and in the production of antibiotics. Pseudonocardia dioxanivorans was first isolated from 1,4-dioxane containing sludge. This organism is able to grow using 1,4-dioxane, a toxic compound used as an industrial solvent, as the sole carbon source.
