Modern Soil Remediation Strategies Including Enhancement of Microbial PAH Degradation Biological treatment of PAH has been demonstrated to be a feasible and common remediation technology which has been successfully applied to the clean‐up of contaminated soils provided that the permeability of the soil is high enough to water and oxygen. Clay‐containing soils as well as poor solubility and low bioavailability of contaminants such as PAH limit the biodegradation of these substances. Because bioavailability of the contaminants is of great importance for successful bioremediation, modern soil remediation strategies include physical‐mechanical steps, the use of surfactants or other solvating agents, chemical or enzymatic oxidation, and the use of thermophilic bacteria. 相似文献

Chances and Limits of Microencapsulation in Progressive Food Industry Microencapsulation has gained importance in food technology especially in coevolution with the developments in functional food and dietary supplements. The aim of microencapsulation is to protect the core material from harsh conditions, so that it keeps its nutritional value. Although microencapsulation is in an early state of development, it seems to be necessary to evaluate the chances and risks of this technology. Because of the effects which can be reached by using the microencapsulation process there seems to be a great potential for the developments of new products or products with an added value. This contribution reviews the chances of microencapsulation in the food industry and tries to present and evaluate the limits of this new technology. 相似文献

Applications of Magnetic Resonance for Investigating Water‐, Temperature‐ and Poredistributions in Food Process Engineering Various methods of nuclear magnetic resonance (NMR) and their application for determinig water‐ and temperature distributions as well as self diffusion coefficients during food processing operations are presented. Starting from the physical basics of the magnetic resonance, various NMR applications are shown, which may contribute to a more comprehensive understanding of the food processes: Presented examples are the determination of water distributions during the rehydration of dried samples, of temperature distributions during a microwave heating process and of self diffusion coefficients during microwave vacuum drying. These observation time dependent self diffusion coefficients may be used to receive further information about the internal tissue structure, like tortuosity and pore radii. 相似文献
