Advanced Nano-Bio Technologies for Water and Soil Treatment

Abstract

New trends in bioremediation are reviewed with the major focus on applications of both synthetic and biological surfactants including high molecular weight bioemulsifiers. The use of eco-friendly biosurfactants is discussed including their applications for removal of heavy metals from soil in addition to traditional organic contaminants. Both success stories and limitations of biosurfactant applications are described on the basis of current literature. Another newly developed technology, the use of enzymes (free or immobilized) instead of/in combination with microorganisms is discussed with respect to removal of both organic contaminants and metals from soil along with addressing the key disadvantage of the enzyme application, which is its high cost. Application of genetically modified organisms, i.e., microorganisms and plants, for soil bioremediation is reviewed focusing on introduction into the environment as well as contained use in closed reactors. Finally, a brief review is provided on the current research and application of biopesticides as promising agents for prevention of soil contamination.
