Bioremediation of Contaminated Soils

Bioremediation techniques: towards an ecosystem approach to remediation in the Great Basin; experimental investigations on in-situ bioremediation of an aquifer contaminated with ammonium; remediation of hexavalent chromium by biosorption; bioregeneration of contaminated absorbents containing hazardous wastes; efficiency of cyperus corymbosus, typha angustifolia, phragmites, australis, and eleocharis dulcis in constructed wetlands for chromium treatment of electroplating industrial wastewater; microbiological peculiarities of cattle waste transformation into food additions; the increase of pea cells sensitivity to chemical compounds during chromatin activation periods; modification of biological process of treatment - real way to improve effluent. Bioremediation of hydrocarbon contaminated materials: biodegradation of PCBs in aqueous and soil systems; biosurfactant production by indigenous soil microbes degrading BEPH and lubricating oil; potential of plant-microbial interactions for in-situ bioremediation of hydrocarbon-contaminated soils; concurrent fuel and chlorinated solvent remediation -bioslurping free product and monitored natural attenuation of the soluble plume; biodegradation of crude oil in cold climate conditions - summary of the methods used to study biodegradability; additives affecting the microbial degradation of petroleum hydrocarbons; intrinsic biodegradation of benzene in contaminated groundwater - a case study illustrating the application of numerical modelling. Soil-specific bioremediation techniques: bioaugmentation for soil bioremediation; degradation of aromatic xenobiotics in soil by enzyme systems of microorganisms and plants; removal of heavy oil sludge contamination by composing; bioremediation of TNT-contaminated soil; in-situ remediation of contaminated soils by bioelectrokinetic remediation and other competitive technologies; aerobic biodegradation kinetics and soil gas transport in the unsaturated zone.
