Microbial degradation of hydrocarbon contaminated soil is often limited by lack of oxygen and poor bioavailability of contaminants. The authors present an approach to solve these problems by treating the soil in a rotary drum reactor with grinding beads. Studies involving the moisture content of the soil, the rotational speed, and mixing time indicate that this method is useful in the treatment of such soils.
