Biotechnology may provide an efficient and environmentally friendly route to the management of industrial wastes. Microbes in particular, owing to their ability to proliferate in most ecological niches, can be engineered for the immobilization of metal pollutants. The utilization of chromium in steel production, wood preservation, leather tanning, paints and pigments has led to a sharp increase of this metal in the environment where it occurs primarily in trivalent or hexavalent forms. In trace amounts chromium is considered an essential nutrient for numerous organisms; in elevated concentrations it is toxic and mutagenic. This study investigated the interaction of Chromium (III) on the soil bacterium Pseudomonas fluorescens. 17 refs., 3 figs.
