The polyphosphate kinase gene from Pseudomonas aeruginosa was overexpressed in its native host, resulting in the accumulation of 100 times the polyphosphate seen with control strains. Degradation of this polyphosphate was induced by carbon starvation conditions, resulting in phosphate release into the medium. The mechanism of polyphosphate degradation is(More)
The microstructure, physical characteristics, corrosion behavior, and reactivity of zerovalent iron nanoparticles synthesized on a support (primarily a nonporous, hydrophobic polymer resin) were studied. The remediation of groundwater by zerovalent iron in in situ permeable reactive barriers relies on the redox reaction between metallic iron and a reducible(More)
The spectral and temporal dependence of b-delayed g rays in the range EX3:0 MeV from thermal–neutron-induced fission are shown to be characteristic signatures of 235 U and 239 Pu: For the interrogation of large seagoing cargo containers filled with hydrogenous materials, b-delayed g rays can offer an increase in sensitivity for the detection of these and(More)
The Satellite Climatology Programme SAT-KLIM of the German Meteorological Service (Deutscher Wetterdienst) was established to evaluate the future data of the EUMETSAT programme CM-SAF (Satellite Application Facility on Climate Monitoring). This means that SAT-KLIM will be one important end user of CM-SAF. Since CM-SAF will only provide future operational(More)
We study Deinococcus radiodurans, a nonpathogenic prokaryote able to withstand high doses of ionizing radiation, for bioremediation and biostabilization of heavy metals and actinides to limit the migration of these contaminants. Our goal is to develop a system for D. radiodurans to bioprecipitate actinides similar to that of a genetically engineered strain(More)
