Leucobacter are aerobic heterotrophs with rod shaped morphology 5. Several species within the genus are known to express resistance to chromium (Cr(VI)) 6 7 8 9, with a demonstrated ability for chromium reduction 6 7. Generally, Leucobacter show poor substrate utilisation with a limited ability to assimilate many carbohydrates and carbon sources. Nothing is known of their importance in activated sludge.
