ABSTRACT

The effectiveness of bioremediation of hazardous compounds is mainly influenced by the degradability and the toxicity of the compounds present. Bioremediation has been used to treat soils and aquifers contaminated by hydrocarbons, phenols, cyanides, and chlorinated solvents. Site enhancement includes modifying site-specific physical and chemical conditions for effective bioremediation. In order for bioremediation to function efficiently, it is essential to understand the various environmental conditions capable of modifying the density, distribution, and overall biochemical potential of the soil microbial ecosystem. Effective modeling of biological systems is needed for research in several areas including bioremediation. The rate of contaminant degradation during in situ bioremediation is directly influenced by the availability of nutrients to the microbes in the soil mass. The engineers develop the systems that combine the substrate and nutrients, the media, and the microorganisms. Applications of biological treatment in treating relatively easily degradable compounds have demonstrated the effectiveness of bioremediation technology.
