In the present study, canola was successfully grown in soil containing concentrations of several metals ranging between 100 and 2000 mg/kg of soil. Different parts of the growing biomass, viz.
shoot, flower, and root, were collected to determine the concentration of metals in each part. As canola biomass can hyperaccumulate many metal contaminants, its enzymatic hydrolysis has two
advantages: the great reduction of metal contamination in soils, and the products that can be derived from the harvested biomass. The large volumes of canola biomass grown annually yield abundant lignocellulose residues. This is a major low-cost source of sugars that can be converted into valuable products such as ethanol by hydrolysis and/or fermentation [6,7].
