Microwave Treatment Of Hazardous Wastes : Feasibility Studies-Mass Balances, Liu Liu
Microwave Treatment Of Hazardous Wastes : Feasibility Studies-Mass Balances, Liu Liu
Theses
This laboratory has been developing processes for the remediation of soils contaminated with hazardous wastes using microwave treatment. The initial stage was to define situations in which microwave treatment could potentially have unique advantages, and to define the relevant physical chemical mechanisms. That having been accomplished, at the present stage, feasibility studies are being carried to determine whether or not on-site field testing is justified. To that end, mass balances on the processes are needed. In this study mass balance studies were carried out on the microwave assisted steam distillation of volatile organic chemicals (VOCs) and semi-volatile organics (SVOCs), respectively, …
Recalcitrance Of Polychlorinated Biphenyls To Biodegradation By Phanerochaete Chrysosporium In Soil, Thierry B. Poncet
Recalcitrance Of Polychlorinated Biphenyls To Biodegradation By Phanerochaete Chrysosporium In Soil, Thierry B. Poncet
Theses
The white rot fungus Phanerochaete chrysosporium has been shown in the past to effectively degrade a number of chlorinated aromatic compounds. Previous investigators (Eaton, D. C., "Mineralization of Polychlorinated Biphenyls by Phanerochaete chrysosporium, a Lignolytic Fungus", Enz. Microb. Technol., 7, 194-196 (1985); Bumpus, J. A., Tien, M., Wright, D., and Aust, S. D., "Oxidation of Persistent Environmental Pollutants by White Rot Fungus", Science, 228, 1434-1436 (1985)) have also claimed that this fungus is capable of mineralizing polychlorinated biphenyls (PCBs) in submerged cultures under stationary conditions. Therefore, the objective of this work was to study the biodegradation activity of the fungus …
